[0001] TECHNICAL FIELD The present application relates to the technical field of mechanical and electrical control.

[0002] A quiet cabin reduces exhaust gas concentrations in the cabin through ventilation during use, preventing user discomfort caused by excessively high exhaust gas concentrations. Ventilation is typically achieved using a ventilation device with a blower, but the operation of the blower generates noise, which interferes with the user experience and impacts the cabin.

[0003] In the prior art, the noise generated by the fan is controlled by adjusting the fan rotation speed.

[0004] It should be noted that the above description of the technical background is only intended to make the technical solutions of the present application clear, complete, and easy to understand for those skilled in the art, and these solutions are not considered to be known to those skilled in the art just because they are described in the background section of the present application.

[0005] The inventors of the present application have discovered that in a space such as a silent cabin, the impact of noise generated by the ventilation device on the user varies depending on the distance between the user and the ventilation device, and therefore, for the user, the problem to be solved is how to accurately control noise at the user's desired location (for example, the user's ears).

[0018] Embodiments of the First Aspect An embodiment of the present application provides a method for controlling noise in a space.

[0019] 1 is a schematic diagram of a method for controlling noise in a space according to an embodiment of the present application, which includes: an operation 101 of identifying a designated location relative to a user; and an operation 102 of controlling an operating state of a ventilation device for the space based on the designated location within the space, so as to control noise at the designated location.

[0020] According to the embodiment of the present application, the operating state of the ventilation device can be controlled based on the user's designated position in the space, thereby accurately controlling noise at the designated position, thereby tailoring noise control to the user's needs and improving the user experience.

[0021] In the present application, the space is provided with a ventilation device for gas exchange between the space and the outside. The ventilation device may have a blower, and for example, the ventilation device may be a ventilation fan, a fresh air facility, or the like. Furthermore, the space may further include a static pressure adjustment device capable of adjusting the static pressure within the space. For example, the static pressure adjustment device may be a device such as a ventilation valve, a window, or a door. The static pressure adjustment device has a passage for gas exchange between the inside and outside of the space, and can adjust the static pressure within the space by changing the area of ​​the passage, thereby controlling the ventilation efficiency.

[0022] 2 is a schematic diagram of a space in which a ventilation device is provided. As shown in FIG. 2, the space 200 may be the interior space of the silent cabin 20. However, the present application is not limited thereto, and the space 200 may be the interior space of another facility, object, or building. In one example, the volume of the space 200 is about 3 m ３ and 3 m ３ Greater than 3m ３ is smaller than

[0023] The silent cabin 20 is also called a silent room, soundproof room / cabin, or concentration room, and the soundproofing performance of the cabin itself prevents external sounds from being transmitted to the interior space, keeping the interior space quiet and ensuring that the user in the cabin can concentrate on creating, studying, resting, or relaxing.

[0024] Ventilation devices 201A, 201B, 201C, and 201D are attached to the silent cabin 20 (i.e., the boundaries of the space 200). The ventilation devices can be used to introduce outside air into the space 200 or to exhaust gases from within the space 200. For example, the ventilation devices 201A and 201B located above the space 200 are used to introduce outside air into the space 200, and the ventilation devices 201C and 201D located below the space 200 are used to exhaust gases from the space 200. Furthermore, the silent cabin 20 may be provided with a static pressure adjustment device 204. The positions of the ventilation device and the static pressure adjustment device are not limited thereto and can be adjusted as needed.

[0025] 2, the number of ventilation devices 201A, 201B, 201C, and 201D is four, but is not limited to this and the number of ventilation devices may be one or more, for example, one, two, three, or more. In FIG. 2, the number of static pressure adjustment devices 204 is one, but is not limited to this and the number of static pressure adjustment devices 204 may be two, three, or more. Furthermore, the silent cabin 20 does not necessarily have to be provided with a static pressure adjustment device 204.

[0026] In this application, the ventilation devices 201A, 201B, 201C, and 201D and the static pressure adjustment device 204 are used to ventilate the space 200, and therefore the space 200 is said to have the ventilation devices 201A, 201B, 201C, and 201D and the static pressure adjustment device 204.

[0027] In the present application, as shown in FIG. 2 , a first air quality sensor 21 may be provided inside the space 200, and a second air quality sensor 22 may be provided outside the space 200. This allows the first air quality sensor 21 to acquire the air quality inside the space 200, and the second air quality sensor 22 to acquire the air quality outside the space 200. Furthermore, the second air quality sensor 22 may not be provided outside the space 200, and the air quality outside the space 200 may be acquired from weather information or the like. The air quality detected by the first air quality sensor 21 and / or the second air quality sensor 22 may be, for example, the amount of carbon dioxide (CO ) in the air. ２ The information includes concentration information of total volatile organic compounds (TVOCs) or other substances in the air, temperature information, humidity information, and the like.

[0028] In operation 101 of the present application, the designated position includes the user's auditory position within the space, where the user's auditory position includes at least one of the user's ear position within the space, the sound pickup position of the user's hearing aid device within the space, and a pre-defined position within the space.

[0029] In the present application, the designated location can be identified by at least one of the following methods:

[0030] The designated position is identified based on the results of image recognition, for example, by having a camera in space 200 take a picture of the user, the position of the user's ears can be recognized based on the image; the designated position is identified based on the detection results of a posture sensor, for example, by using a posture sensor to determine whether the user is standing or sitting, and further determining the position of the user's ears according to the user's posture, that is, the ear positions when standing and when sitting are set in advance, and the ear positions are obtained according to the user's posture; the designated position is a predetermined position, and for example, the predetermined position may include a position at a predetermined height from a table surface in the space, or a position at a predetermined height from a seat in the space, or a position at a predetermined height from the ground in the space, or a position below the top of the space at a predetermined distance from the top.

[0031] Furthermore, if the hearing position is the sound pickup position of the user's hearing aid device in space, the position sensor may also communicate with the hearing aid device to obtain the spatial position of the hearing aid device as the user's hearing position.

[0032] In operation 102 of the present application, controlling the operating state of the ventilation device may include controlling the rotation speed of a blower of the ventilation device.

[0033] In some embodiments, when the number of ventilation devices is two or more, each ventilation device is located at a different position in space 200. In operation 102, controlling the operation state of the ventilation devices includes controlling the rotation speeds of the fans of each ventilation device in accordance with an adjustment target based on a relationship between a combination of fan rotation speeds of each ventilation device and noise, where the combination of fan rotation speeds of each ventilation device corresponds to a ventilation volume. Alternatively, in operation 102, controlling the operation state of the ventilation devices may include controlling the rotation speeds of the fans of each ventilation device in accordance with an adjustment target based on a relationship between a ventilation volume and noise corresponding to the combination of fan rotation speeds of each ventilation device.

[0034] Here, the combinations of the rotation speeds of the blowers of each ventilation device are, for example, as follows: Combination 1, in which the rotation speeds of ventilation devices 201A, 201B, 201C, and 201D are all 1600 revolutions per minute (rpm); Combination 2, in which the rotation speeds of ventilation devices 201A and 201B are both 1200 rpm, and the rotation speeds of 201C and 201D are both 1600 rpm; Combination 3, in which the rotation speeds of ventilation devices 201A and 201C are both 1200 rpm, and the rotation speeds of 201B and 201D are both 1600 rpm; ... Each combination can achieve a corresponding ventilation volume for the space and generate a corresponding amount of noise at the specified position. Different specified positions result in different sets of combinations; for example, for one specified position in space, the set of combinations may be {combination 1, combination 2, combination 3, ...}, and for another specified position in space, the set of combinations may be {combination 1', combination 2', combination 3', ...}.

[0035] In the present application, the adjustment target includes a target ventilation rate or a target noise rate.

[0036] In at least some examples, when the adjustment target is the target ventilation, a combination that satisfies the target ventilation requirement and minimizes noise is identified, and the rotation speed of the blower of each of the ventilation devices is controlled based on the identified combination, where satisfying the target ventilation requirement means, for example, that the ventilation rate of the ventilation device is equal to or greater than the target ventilation rate when the rotation speed of the combination is adopted.

[0037] In at least another example, when the adjustment target is the target noise level, the combination that satisfies the target noise level requirement and maximizes the ventilation volume is identified, and the rotation speed of the fan of each of the ventilation devices is controlled based on the identified combination. Here, satisfying the target noise level requirement means, for example, that when the rotation speed of the combination is adopted, the noise volume generated by the ventilation device at the specified position is equal to or less than the target noise level requirement.

[0038] In this application, if the fans of each ventilation device are continuously adjustable fans, in operation 102, a combination of rotation speeds of each fan corresponding to the adjustment target can be selected.

[0039] In the present application, when the blowers of each ventilation device are non-continuously adjustable blowers, the preset combination of the rotation speeds of the blowers may be discrete rotation speeds. If the preset combination of the rotation speeds of the blowers does not correspond to the adjustment target, the combination of the rotation speeds of the blowers is identified based on preset priorities. For example, when the priority of ventilation volume is higher than the priority of noise volume, a combination of the preset combinations of the rotation speeds of the blowers with a ventilation volume greater than the target ventilation volume may be first selected, and the combination of the initially selected combinations with the smallest noise volume may be identified. Alternatively, when the priority of noise volume is higher than the priority of ventilation volume, a combination of the preset combinations of the rotation speeds of the blowers with a noise volume less than the target noise volume may be first selected, and the combination of the initially selected combinations with the largest ventilation volume may be identified. Furthermore, the combination of the rotation speeds may be set by the user.

[0040] In the present application, the target ventilation rate may be determined based on the air quality within the space (e.g., within space 200) and outside the space, for example, the air quality may be determined based on the amount of carbon dioxide (CO ２ The target noise level may be determined based on a predetermined standard (e.g., a national standard for noise).

[0041] In the present application, the target ventilation rate and / or the target noise rate may be set according to a user. For example, the adjustment target may be determined based on at least one of the noise tolerance and the air quality tolerance of the user in the space 200.

[0042] In some examples, identifying the adjustment target based on the user's noise tolerance or air quality tolerance includes: identifying the adjustment target as a target ventilation rate if the user's noise tolerance is higher than the air quality tolerance; and identifying the adjustment target as a target noise level if the user's air quality tolerance is higher than the noise tolerance.

[0043] Specifically, noise tolerance and air quality tolerance can be expressed by a numerical value, and a larger or smaller numerical value can indicate higher tolerance.

[0044] Further, in operation 102, if only one of the user's noise tolerance and air quality tolerance is obtained, an adjustment target is identified based on the obtained noise tolerance or air quality tolerance.

[0045] As shown in FIG. 1 , the method for controlling noise in the space may further include: an operation 103 of acquiring personal information of a user; and an operation 104 of acquiring corresponding noise tolerance and air quality tolerance based on the acquired personal information of the user.

[0046] For example, the user's personal information can be obtained by performing facial recognition on the user or by reading the user's card or two-dimensional code using a recognition device, and the user's noise tolerance and air quality tolerance can be searched for in a database based on the personal information.

[0047] As shown in FIG. 1 , the method for controlling noise in the space may further include operation 105 of identifying or storing, based on the designated location, a relationship between a combination of fan rotation speeds of each of the ventilation devices and the noise level at the designated location, or identifying or storing, based on the designated location, a relationship between a ventilation volume corresponding to a combination of fan rotation speeds of each of the ventilation devices and the noise level at the designated location.

[0048] As the designated location changes, a relationship between the combination of RPMs of the blower of the ventilation device (or the ventilation volume corresponding to the combination of RPMs) and the noise volume at the designated location can be identified or stored through operation 105. This allows a three-way correspondence relationship to be formed between the designated location, the combination of RPMs of the blower of the ventilation device (or the ventilation volume corresponding to the combination of RPMs), and the noise volume at the designated location.

[0049] In some embodiments, the correspondence may be pre-identified and stored so that it can be invoked in operation 102, or in other embodiments, a formula for the correspondence may be pre-fitted or a neural network model for the correspondence may be pre-trained and the formula or neural network model may be stored, so that in operation 102 the stored formula or neural network model can be invoked to control the operating state of the ventilator.

[0050] In some examples, a space (e.g., space 200) is divided into multiple sub-spaces (e.g., each sub-space may have the same or different volume and may have the same or different shape), and for each sub-space, a relationship can be maintained between a pre-measured combination of fan speeds of each ventilation device (or the ventilation volume corresponding to that combination of speeds) and the noise volume of that sub-space.

[0051] In operation 105, based on the designated position identified in operation 101, the relationship between the combination of rotation speeds of the fans of each ventilation device and the noise level at the designated position can be identified using the relationship between the noise level at the subspace to which the designated position belongs and the combination of rotation speeds of the fans of each ventilation device (or the ventilation rates corresponding to the combination of rotation speeds) of the fans of the ventilation devices corresponding to subspace A. For example, if designated position a belongs to subspace A (i.e., designated position a is located within subspace A), relationship A1 between the noise level at the designated position and the combination of rotation speeds of the fans of each ventilation device corresponding to subspace A (or the ventilation rates corresponding to the combination of rotation speeds) may be defined as relationship a1 between the noise level at the designated position and the combination of rotation speeds of the fans of each ventilation device corresponding to designated position a (or the ventilation rates corresponding to the combination of rotation speeds).

[0052] As shown in FIG. 1, the method for controlling noise in the space further includes an operation 106 of controlling a passage area of ​​a static pressure adjusting device for gas exchange into and out of the space based on the designated location within the space.

[0053] As a result, when a static pressure adjustment device is present in the space, by combining the area of ​​the gas exchange passage with the rotation speed of the blower of each ventilation device, it is possible to more accurately control the amount of noise in the space in addition to controlling the static pressure adjustment device, and furthermore, it is possible to achieve both control of ventilation volume and control of noise volume.

[0054] The method for controlling noise in a space of the present application will be further described below based on several examples.

[0055] <Example 1> In Example 1, the fans of the ventilation devices 201A, 201B, 201C, and 201D are all infinitely adjustable fans.

[0056] For example, a space such as the space 200 shown in FIG. 2 (for example, a space with a volume of about 3 m ３In the ventilation devices 201A, 201B, 201C, and 201D, the pressure difference between the inside and outside of the space (i.e., the absolute air pressure inside the space minus the absolute air pressure outside the space) can be changed by adjusting the rotation speed of the blower of any one of the ventilation devices 201A, 201B, 201C, and 201D. For example, if the rotation speeds of the blowers of the ventilation devices 201A, 201B, and 201C are kept constant and only the rotation speed of the ventilation device 201D is adjusted, the pressure change rule shown in Table 1 below will be obtained.

[0057]

[0058] Adjusting the rotation speed of the fan in the ventilation device also changes the noise level, and if the noise level increases, it will have a serious impact on the work efficiency of the user in the space.

[0059] Currently, the common method is to adjust the speed or power of a single fan to reduce the ventilation rate and achieve low noise levels. However, this results in a low ventilation rate and a high CO2 content in the space. ２ The concentration of gases such as CO increases rapidly. ２ The environment also affects the user's work efficiency and ultimately their health. How to balance the relationship between noise level and ventilation volume has become a difficult issue in the industry.

[0060] Although the same ventilation volume may be achieved by combining different fan speeds, the noise level differs depending on the combination. Therefore, in this application, by calculating the target ventilation volume, it is possible to identify the combination of fan speeds that will minimize the noise level at the specified position. By controlling the fan speeds of each ventilation device, the required ventilation volume within the space and the required noise level at the specified position can both be achieved.

[0061] 3 is a schematic diagram of a method for controlling noise in a space according to Example 1. As shown in FIG. 3, the method for controlling noise in a space according to Example 1 includes: ２ The CO 2 concentration is collected by, for example, a first air quality sensor 21 and a second air quality sensor 22 inside and outside the space. ２The method includes an operation 301 of acquiring concentration data; an operation 302 of calculating a target ventilation volume, for example, calculating the target ventilation volume based on a conventional technology method; an operation 303 of searching for a corresponding combination from preset combinations of fan rotation speeds of each ventilation device based on the target ventilation volume, for example, searching a database for a combination of fan rotation speeds that matches the target ventilation volume; an operation 304 of acquiring a combination that produces the lowest noise from the combinations searched in operation 303; and an operation 305 of adjusting the rotation speed of the fan of the corresponding ventilation device based on the combination obtained in operation 304.

[0062] The above operations 301 to 305 can be performed in cycles.

[0063] Here, the preset combination of the rotation speeds of the fans of each ventilation device in operation 303 may be data obtained by conducting a large amount of tests based on the structural state of the preset space, and for example, the preset combination can be obtained by the following method.

[0064] The rotation speed of the fan of one ventilation device is adjusted, and the fans of the remaining ventilation devices all maintain a constant rotation speed. The air volume and noise volume within the rotation speed adjustment range of the fans of the ventilation devices are actually tested and measured, and the data is recorded in a database. For example, the following set is obtained:

[0065] Set (i) of combinations of rotation speeds: The rotation speeds of the fans of the ventilation devices 201B, 201C, and 201D are kept constant at 1600 rpm, the rotation speed of the fan of the ventilation device 201A is adjusted, and the ventilation volume and the corresponding noise volume (for example, the corresponding noise volume refers to the noise volume detected at a certain specified position) during the process of change in the rotation speed of the fan of the ventilation device 201A are recorded to obtain a plurality of combinations of rotation speeds, and the plurality of combinations of rotation speeds may be defined as the same set, for example, set (i) of combinations of rotation speeds; Set (ii) of rotation speed combinations: The rotation speed of the fan of ventilation device 201B is kept constant at 1200 rpm, the rotation speeds of the fans of ventilation devices 201C and 201D are kept constant at 1600 rpm, the rotation speed of the fan of ventilation device 201A is adjusted, and the ventilation volume and the corresponding noise level (for example, the corresponding noise level refers to the noise level detected at a specified position) are recorded during the process of changing the rotation speed of the fan of ventilation device 201A to obtain multiple rotation speed combinations, and the multiple rotation speed combinations may be defined as the same set, for example, set (ii) of rotation speed combinations; Set (iii) of rotation speed combinations: ... The rotation speeds of the fans of ventilation devices 201A, 201B, 201C, and 201D can all be adjusted individually (for example, by adjusting the rotation speed using a pulse width modulation method or a voltage adjustment method), thereby forming a large number of sets of rotation speed combinations, and each set includes multiple rotation speed combinations. Here, only a set of combinations of two types of rotation speeds will be described.

[0066] In the present application, the relationship between ventilation volume and noise volume obtained by testing different combinations of rotation speeds can be plotted as a graph, with ventilation volume on the horizontal axis and noise volume on the vertical axis. Figure 4 is a schematic diagram showing the relationship between ventilation volume and noise volume obtained by testing different combinations of rotation speeds. In Figure 4, curve 401 corresponds to set (i) of combinations of rotation speeds, and curve 402 corresponds to set (ii) of combinations of rotation speeds.

[0067] For example, the target ventilation volume is 120 m ３ / h, as can be seen from FIG. 4, the noise value (53 dBA) of the curve 402 is smaller, and therefore, the ventilation volume is 120 m / s in the set (ii) of the combination of the rotational speeds. ３ / h, and then the rotation speeds of the fans of the ventilation devices 201A, 201B, 201C, and 201D in the selected rotation speed combination are searched from the database.

[0068] Note that the set of rotation speed combinations (i), the set of rotation speed combinations (ii), the set of rotation speed combinations (iii), etc. described in Example 1 are all sets of rotation speed combinations targeted at the same position within space 200. In other words, tests can be performed on different positions within space 200 to obtain rotation speed combinations or sets of rotation speed combinations corresponding to each of the different positions. Here, different positions within space 200 may be represented by the distance between the position and a different ventilation device, or may be represented by the relative positional relationship between the position and another reference position within the space (e.g., the top or bottom of the space). When operation 303 is executed, a rotation speed combination that satisfies the conditions is searched for from the preset combinations of the fan speeds of each ventilation device that correspond to the specified position, based on the specified position identified in operation 101.

[0069] Furthermore, in a modification of the first embodiment, multiple combinations of rotation speeds in the database may be processed so as to retain one or several combinations with low noise for the same ventilation volume. In this way, the amount of data stored for the same ventilation volume can be reduced, and at the time of use, the multiple combinations can be selected based on user information or other information, thereby increasing the speed of control.

[0070] <Example 2> Example 2 differs from Example 1 in that in Example 2, the fans of ventilation devices 201A, 201B, 201C, and 201D are all non-infinitely adjustable fans, for example, fans having fixed operation stages.

[0071] In the second embodiment, noise in the space 200 can be controlled in a manner similar to that shown in FIG.

[0072] Here, the preset combination of the rotation speeds of the fans of each ventilation device in operation 303 may be data obtained by conducting a large amount of tests based on the structural state of the preset space, and for example, the preset combination can be obtained by the following method.

[0073] The rotation speed of the fan of one ventilation device is adjusted (for example, the stage of the fan is adjusted), and the fans of the remaining ventilation devices are all maintained at a constant rotation speed. The air volume and noise volume within the rotation speed adjustment range of the fans of the ventilation devices are actually tested and measured, and the data is recorded in a database, and for example, the following set is obtained:

[0074] Set (i) of rotation speed combinations: The rotation speeds of the fans of the ventilation devices 201B, 201C, and 201D are kept constant at 1600 rpm, and the stage of the fan of the ventilation device 201A is adjusted to adjust the rotation speed of the fan, and the ventilation volume and the corresponding noise volume during the change of the stage of the fan of the ventilation device 201A are recorded to obtain a plurality of rotation speed combinations (i.e., stage combinations), and the plurality of rotation speed combinations may be defined as a single set, for example, set (i) of rotation speed combinations; Set of rotation speed combinations (ii): The rotation speed of the fan of ventilation device 201B is kept constant at 1200 rpm, the rotation speeds of the fans of ventilation devices 201C and 201D are kept constant at 1600 rpm, the stage of the fan of ventilation device 201A is adjusted to adjust the rotation speed of the fan, and the ventilation volume and corresponding noise level (for example, the corresponding noise level refers to the noise level detected at a specified position) during the process of changing the stage of the fan of ventilation device 201A are recorded to obtain multiple rotation speed combinations (i.e., stage combinations), and the multiple rotation speed combinations may be defined as the same set, for example, set of rotation speed combinations (ii); Set of rotation speed combinations (iii): The rotation speeds (e.g., stages) of the fans of ventilation devices 201A, 201B, 201C, and 201D can be adjusted individually to form a set of multiple rotation speed combinations, and each set includes multiple rotation speed combinations. Here, only a set of combinations of two types of rotation speeds will be described.

[0075] In this application, the relationship between ventilation volume and noise volume obtained by testing different combinations of rotation speeds (i.e., combinations of stages) can be plotted as a graph, with ventilation volume on the horizontal axis and noise volume on the vertical axis. Figure 5 shows a schematic diagram of the relationship between ventilation volume and noise volume obtained by testing different combinations of rotation speeds.

[0076] Because the fan of the ventilation system of Example 2 is a non-infinitely adjustable fan, the relationship between ventilation volume and noise volume obtained by testing different combinations of rotation speeds is expressed as discrete points on a graph. In Figure 5, point 501 corresponds to set (i) of rotation speed combinations of Example 2, and point 502 corresponds to set (ii) of rotation speed combinations of Example 2.

[0077] For example, the target ventilation volume is 120 m ３ / h, and if there is no point corresponding to the target ventilation rate among points 501 and 502 in FIG. 5, the target ventilation rate can be adjusted. For example, the target ventilation rate can be set within a certain range (for example, 120 to 130 m ３ / h) to find the combination of rotation speeds (i.e., the combination of stages) that produces the lowest noise within the range of the adjusted target ventilation volume, and then search the database for the rotation speeds (i.e., the stages) of the fans of the ventilation devices 201A, 201B, 201C, and 201D for that combination of rotation speeds.

[0078] Furthermore, the same contents of the second embodiment as those of the first embodiment can be referred to, and will not be described again here.

[0079] In some examples of Example 2 and Example 1, the designated position within the space may be the position of the user's ear, and the designated position may be represented by the distance between the user's ear and each ventilation device, for example. Here, when the user's posture or position within the space moves, the distance between the user's ear and each ventilation device may change, and therefore the designated position also changes.

[0080] 6 is a schematic diagram in which the position of a user's ear is designated as a designated position within a space. As shown in FIG. 6 , the designated position is the position of ear 601 of user 600 within space 200 inside silent cabin 20. The distance between ear 601 and each of blowers A, B, C, and D can be detected using image recognition or other methods. Here, blower A may correspond to ventilation device 201A in FIG. 2 , blower B may correspond to ventilation device 201B in FIG. 2 , and blower C may correspond to ventilation device 201D in FIG. 2 .

[0081] For example, the distance between the ear 601 and the fan A is La, the distance between the ear 601 and the fan B is Lb, the distance between the ear 601 and the fan C is Lc, and the distance between the ear 601 and the fan D is Ld.

[0082] Note that the position of the fan D in Fig. 6 is different from the position of any of the ventilation devices in Fig. 2, but the description of each ventilation device in Fig. 2 can be applied to the fan D in Fig. 6. Furthermore, the number and positions of the fans in Fig. 6 are merely an example, and the present application is not limited thereto.

[0083] In at least one example, the distance between the user's ear and each ventilation device (e.g., La, Lb, Lc, Ld) may be stored to represent a designated position within the space, and for example, the three elements of the distance between the user's ear and each ventilation device, the combination of rotation speeds of the ventilation device's fans (or the ventilation volume corresponding to the combination of rotation speeds), and the noise volume at the designated position may be stored in correspondence with each other to reflect the correspondence between the designated position, the combination of rotation speeds of the ventilation device's fans (or the ventilation volume corresponding to the combination of rotation speeds), and the noise volume at the designated position.

[0084] In Example 3, the area of ​​the passage for gas exchange between the inside and outside of the space of the static pressure adjusting device 204 can be controlled based on a designated position within the space. In Example 3, the number of ventilation devices included in the space 200 may be one or more.

[0085] In Example 3, new combinations may be formed by adding the area of ​​the gas exchange passage to the combinations of the rotation speeds of the blowers of each ventilation device in Example 1 or Example 2. For example, by storing in advance in a database combinations of the rotation speeds of the blowers of each ventilation device and the area of ​​the gas exchange passage, as well as data such as the ventilation volume and noise volume corresponding to each combination, it is possible to select a combination that minimizes the noise volume from the target ventilation volume, and to adjust the rotation speed of the blower and the area of ​​the gas exchange passage of each ventilation device based on the combination. Here, the method of adjusting the area of ​​the gas exchange passage may be, for example, adjusting the opening angle of a door or window, or adjusting the opening area or opening / closing angle of a valve.

[0086] In the third embodiment, in addition to the control of the static pressure adjusting device, it is possible to more accurately control the noise level in the space, and it is also possible to control both the ventilation volume and the noise level. Furthermore, the description of the designated position in Figure 6 also applies to the third embodiment.

[0087] In the above-described first, second, and third embodiments, the adjustment target is a target ventilation volume. In the case where the adjustment target is a target noise volume, the above description can be referred to.
