Ventilation is usually carried out by using a ventilation device with a fan. However, when the fan operates, it will generate noise, causing interference to users inside the cabin and affecting the user experience.

[0030] Embodiment of the first aspect

[0031] An embodiment of the present application provides a method for controlling spatial noise.

[0032] Figure 1 is a schematic diagram of the method for controlling spatial noise according to an embodiment of the present application. As Figure 1 shown, the method for controlling spatial noise includes:

[0033] Operation 101, determining a specified position related to the user;

[0034] Operation 102, based on the specified position within the space, controlling the operating state of the ventilation device in the space to control the noise at the specified position.

[0035] According to an embodiment of the present application, by controlling the operating state of the ventilation device based on the specified position related to the user within the space, the noise at the specified position can be accurately controlled, making the noise control match the user's needs and enhancing the user experience.

[0036] In the present application, the space is provided with a ventilation device, which enables gas exchange between the space and the outside. The ventilation device may have a fan. For example, the ventilation device may be a ventilation fan, a fresh air device, etc. In addition, the space may also have a static pressure regulating device, which can regulate the static pressure within the space. For example, the static pressure regulating device may be a ventilation valve, a window, a door, etc. The static pressure regulating device has a channel for gas exchange between the inside and outside of the space. By changing the area of this channel, the static pressure within the space can be regulated, thereby controlling the ventilation efficiency.

[0037] Figure 2 is a schematic diagram of a space provided with a ventilation device. As Figure 2 shown, the space 200 may be the internal space of the soundproof cabin 20. In addition, the present application is not limited thereto, and the space 200 may also be the internal space of other facilities, objects or buildings, etc. In one example, the volume of the space 200 is about 3 m 3 , greater than 3 m 3 , or less than 3 m 3 .

[0038] The soundproof cabin 20 is also known as a soundproof chamber, a soundproof room / cabin, a concentration room, etc. It blocks external sounds from entering the internal space through the soundproof performance of the cabin body, keeping the internal space quiet to ensure that users inside the cabin can focus on creation, study, or relaxation.

[0039] Ventilation devices 201A, 201B, 201C, and 201D are installed at the boundary of the soundproof cabin 20 (i.e., the space 200). Among them, the ventilation devices can be used to introduce external gas into the space 200 or extract the gas inside the space 200. For example, the ventilation devices 201A and 201B located above the space 200 are used to introduce external gas into the space 200, and the ventilation devices 201C and 201D located below the space 200 are used to extract the gas inside the space 200. In addition, the soundproof cabin 20 can also be provided with a static pressure regulating device 204. The positions of the ventilation devices and the static pressure regulating device are not limited to this and can be adjusted as needed.

[0040] In Figure 2 In, the number of the ventilation devices 201A, 201B, 201C, and 201D is 4, but it is not limited to this. The number of the ventilation devices can be more than 1, for example, 1, 2, 3, or more. In Figure 2 In, the number of the static pressure regulating device 204 is 1, but it is not limited to this. The number of the static pressure regulating device 204 can be 2, 3, or more. In addition, the soundproof cabin 20 can also not be provided with the static pressure regulating device 204.

[0041] In this application, the ventilation devices 201A, 201B, 201C, and 201D and the static pressure regulating device 204 are used to ventilate the space 200. Therefore, it is said that the space 200 is provided with the ventilation devices 201A, 201B, 201C, and 201D and the static pressure regulating device 204.

[0042] In this application, as Figure 2 shown, a first air quality sensor 21 can be provided inside the space 200, and a second air quality sensor 22 can be provided outside the space 200. Thus, the air quality inside the space 200 can be obtained through the first air quality sensor 21, and the air quality outside the space 200 can be obtained through the second air quality sensor 22. In addition, the second air quality sensor 22 may not be provided outside the space 200, but the air quality outside the space 200 can be obtained through meteorological information, etc. The air quality detected by the first air quality sensor 21 and / or the second air quality sensor 22 refers to, for example, the concentration information of carbon dioxide (CO2) in the air, the concentration information of total volatile organic compounds (TVOC), or the concentration information of other substances in the air, temperature information, humidity information, etc.

[0043] In operation 101 of the present application, the designated position includes: the auditory position of the user within the space. Wherein, the auditory position of the user includes at least one of the following positions: the ear position of the user within the space; the sound collection position of the hearing aid device of the user within the space; a preset position within the space.

[0044] In the present application, the designated position can be determined by at least one of the following methods:

[0045] Determine the designated position through the result of image recognition. For example, a camera within space 200 captures the user, so that the ear position of the user can be recognized according to the picture;

[0046] Determine the designated position through the detection result of the attitude sensor. For example, judge whether the user's posture is standing or sitting through the attitude sensor, and then judge the position of the user's ears according to the user's posture, that is, preset the ear positions in the standing posture and the sitting posture, and match the user's posture to obtain the ear position;

[0047] The designated position is a preset position. For example, the preset position can include a position at a preset height from the desktop within the space, or a position at a preset height from the seat within the space, or a position at a preset height from the ground within the space, or a position at a preset distance from the top of the space below the top of the space, etc.

[0048] In addition, when the auditory position is the sound collection position of the hearing aid device of the user within the space, the spatial position of the hearing aid device can also be obtained by communicating with the hearing aid device through the position sensor and used as the auditory position of the user.

[0049] In operation 102 of the present application, controlling the operating state of the ventilation device can include: controlling the rotation speed of the fan of the ventilation device.

[0050] In some embodiments, when the number of ventilation devices is more than 2, each ventilation device is located at a different position in space 200. In operation 102, controlling the operating state of the ventilation device includes: based on the relationship between the rotation speed combination of the fans of each ventilation device and the noise, controlling the rotation speed of the fans of each ventilation device according to the adjustment target. Wherein, the rotation speed combination of the fans of each ventilation device corresponds to the ventilation volume. Or, in operation 102, controlling the operating state of the ventilation device can also include: based on the relationship between the ventilation volume corresponding to the rotation speed combination of the fans of each ventilation device and the noise, controlling the rotation speed of the fans of each ventilation device according to the adjustment target.

[0051] Among them, the rotation speed combination of the fans of each ventilation device is, for example:

[0052] Combination 1, the rotation speeds of ventilation devices 201A, 201B, 201C, and 201D are all 1600 revolutions per minute (rpm);

[0053] For Combination 2, the rotational speeds of the ventilation devices 201A and 201B are both 1200 rpm, and the rotational speeds of 201C and 201D are both 1600 rpm;

[0054] For Combination 3, the rotational speeds of the ventilation devices 201A and 201C are both 1200 rpm, and the rotational speeds of 201B and 201D are both 1600 rpm;

[0055] ……

[0056] Each combination can achieve a corresponding ventilation volume for the space and generate a corresponding noise volume at the specified position. For different specified positions, the set of combinations is also different. For example, for a certain specified position within the space, the set of combinations can be {Combination 1, Combination 2, Combination 3, ……}, and for another specified position within the space, the set of combinations can be {Combination 1’, Combination 2’, Combination 3’, ……}.

[0057] In this application, the adjustment targets include: the target ventilation volume or the target noise volume.

[0058] In at least some examples, when the adjustment target is the target ventilation volume, determine the combination that meets the target ventilation volume requirement and has the minimum noise, and control the rotational speeds of the fans of the respective ventilation devices based on the determined combination. Here, meeting the target ventilation volume requirement means that, for example, when the rotational speeds of the combination are adopted, the ventilation volume of the ventilation device is greater than or equal to the target ventilation volume.

[0059] In at least some other examples, when the adjustment target is the target noise, determine the combination that meets the target noise volume requirement and has the maximum ventilation volume, and control the rotational speeds of the fans of the respective ventilation devices based on the determined combination. Here, meeting the target noise volume requirement means that, for example, when the rotational speeds of the combination are adopted, the noise volume generated by the ventilation device at the specified position is less than or equal to the target noise requirement.

[0060] In this application, when the fans of the respective ventilation devices are stepless adjustment fans, the rotational speed combinations of the respective fans corresponding to the adjustment target can be selected in operation 102.

[0061] In the present application, when the fans of each ventilation device are non-steplessly adjustable fans, the preset combinations of the rotational speeds of the fans can be discrete rotational speeds. If the preset combinations of the rotational speeds of the fans do not correspond to the adjustment target, then the combinations of the rotational speeds of the fans are determined according to the preset priorities. For example, when the priority of the ventilation volume is higher than the priority of the noise volume, combinations with a ventilation volume greater than the target ventilation volume can be initially selected from the preset combinations of the rotational speeds of the fans, and the combination with the smallest noise volume among the initially selected multiple combinations is used as the determined combination. For another example, when the priority of the noise volume is higher than the priority of the ventilation volume, combinations with a noise less than the target noise volume can be initially selected from the preset combinations of the rotational speeds of the fans, and the combination with the largest ventilation volume among the initially selected multiple combinations is used as the determined combination. In addition, the combinations of the rotational speeds can also be set by the user.

[0062] In the present application, the target ventilation volume can be determined according to the air quality inside (e.g., inside space 200) and outside the space. For example, the air quality can be the concentration information of carbon dioxide (CO2) in the air, the concentration information of total volatile organic compounds (TVOC), or the concentration information of other substances in the air, temperature information, humidity information, etc. In addition, the target noise volume can be determined according to a predetermined standard (e.g., national standards related to noise, etc.).

[0063] In the present application, at least one of the target ventilation volume and the target noise volume can be set by the user. For example, the adjustment target can be determined according to at least one of the noise tolerance and the air quality tolerance of the user inside space 200.

[0064] In some examples, determining the adjustment target according to the noise tolerance or the air quality tolerance of the user includes:

[0065] When the noise tolerance of the user is higher than the air quality tolerance, the adjustment target is determined to be the target ventilation volume;

[0066] When the air quality tolerance of the user is higher than the noise tolerance, the adjustment target is determined to be the target noise volume.

[0067] Specifically, the noise tolerance and the air quality tolerance can be represented by numerical values. The larger or smaller the numerical value, the higher the tolerance can be represented.

[0068] In addition, if only one of the noise tolerance and the air quality tolerance of the user is obtained in operation 102, then the adjustment target is determined according to the obtained noise tolerance or air quality tolerance.

[0069] As Figure 1 shown, the method for controlling the space noise can further include:

[0070] Operation 103: Obtain the identity information of the user; and

[0071] Operation 104: According to the obtained identity information of the user, obtain the corresponding noise tolerance and air quality tolerance.

[0072] For example, face recognition can be performed on the user or the user's card or QR code can be read through an identification device, so as to obtain the identity information of the user, and based on this identity information, the noise tolerance and air quality tolerance of the user can be retrieved from the database.

[0073] As Figure 1 shown, the method for controlling the space noise may further include:

[0074] Operation 105: Based on the specified position, determine or store the relationship between the rotational speed combination of the fans of each ventilation device and the noise amount at the specified position; or, based on the specified position, determine or store the relationship between the ventilation volume corresponding to the rotational speed combination of the fans of each ventilation device and the noise amount at the specified position.

[0075] Through Operation 105, as the specified position changes, the relationship between the rotational speed combination of the fans of the ventilation device (or the ventilation volume corresponding to the rotational speed combination) and the noise amount at the specified position can be determined or stored. Thus, a corresponding relationship among the specified position, the rotational speed combination of the fans of the ventilation device (or the ventilation volume corresponding to the rotational speed combination), and the noise amount at the specified position can be formed.

[0076] In some embodiments, the corresponding relationship can be determined and stored in advance for Operation 102 to call; or, in other embodiments, a calculation formula related to the corresponding relationship can be pre-fitted or a neural network model related to the corresponding relationship can be pre-trained, and the calculation formula or the neural network model can be stored. Thus, Operation 102 can call the stored calculation formula or the neural network model to control the operating state of the ventilation device.

[0077] In some embodiments, the space (e.g., Space 200) is divided into multiple sub-spaces (e.g., the volume and shape of each sub-space can be the same or different). For each sub-space, a relationship between the rotational speed combination of the fans of each ventilation device (or the ventilation volume corresponding to the rotational speed combination) and the noise amount in the sub-space, which is pre-determined, can be maintained.

[0078] In operation 105, based on the specified position determined in operation 101, the relationship between the rotational speed combination of the fans of each ventilation device in the subspace to which the specified position belongs (or the ventilation volume corresponding to the rotational speed combination) and the noise level in the subspace can be used to determine the relationship between the rotational speed combination of the fans of each ventilation device and the noise level at the specified position. For example, if the specified position a belongs to subspace A (i.e., the specified position a is within subspace A), the relationship A1 between the rotational speed combination of the fans of each ventilation device corresponding to subspace A (or the ventilation volume corresponding to the rotational speed combination) and the noise level at the specified position can be used as the relationship a1 between the rotational speed combination of the fans of each ventilation device corresponding to the specified position a (or the ventilation volume corresponding to the rotational speed combination) and the noise level at the specified position.

[0079] As Figure 1 shown, the method for controlling the noise in the space further includes:

[0080] Operation 106: Based on the specified position in the space, control the area of the channel for gas exchange between the inside and outside of the space of the static pressure regulating device.

[0081] Thus, when the space is equipped with a static pressure regulating device, the area of the gas exchange channel is combined with the rotational speed of the fans of each ventilation device. In this way, it is possible to further accurately control the noise level in the space by combining the control of the static pressure regulating device. In addition, the control of the ventilation volume and the noise level can be taken into account.

[0082] Next, several embodiments will be combined to further illustrate the method for controlling the noise in the space of the present application.

[0083] Embodiment 1

[0084] In Embodiment 1, the fans of the ventilation devices 201A, 201B, 201C, and 201D are all stepless adjustable fans.

[0085] In a space such as Figure 2 the space 200 shown (for example, with a volume of about 3 m 3 or less), by adjusting the rotational speed of any one of the fans of 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 value inside the space minus the absolute air pressure value outside the space) can be changed. For example, when the fans of the ventilation devices 201A, 201B, and 201C maintain a constant rotational speed and only the rotational speed of the ventilation device 201D is adjusted, there is a pressure change law as shown in Table 1 below.

[0086] Table 1

[0087]

[0088] Adjusting the rotational speed of the fan in the ventilation device also brings about a change in the noise level. A high noise level will seriously affect the working efficiency of users in the space.

[0089] The current common practice is to adjust the rotational speed or power of a single fan to reduce the ventilation volume so as to achieve low noise. However, this will result in a low ventilation volume, and the concentration of gases such as CO2 in the space will increase sharply. A high-concentration CO2 environment will also affect the working efficiency of users and even their health. How to balance the relationship between the noise level and the ventilation volume has become a difficult problem in the industry.

[0090] Under the same ventilation volume, there can be different combinations of fan rotational speeds, but the noise levels in these combinations are different. Therefore, in this application, the target ventilation volume can be calculated to determine the combination of fan rotational speeds with the lowest noise level at a specified position. Thus, the rotational speeds of the fans in each ventilation device are controlled, taking into account both the ventilation volume requirement in the space and the noise level requirement at the specified position.

[0091] Figure 3 It is a schematic diagram of the method for controlling the space noise in Embodiment 1. As Figure 3 shown, the method for controlling the space noise in Embodiment 1 includes:

[0092] Operation 301: Collect the CO2 concentrations inside and outside the space. For example, obtain the CO2 concentration data inside and outside the space through the first air quality sensor 21 and the second air quality sensor 22 inside and outside the space;

[0093] Operation 302: Calculate the target ventilation volume. For example, calculate the target ventilation volume according to the prior art method;

[0094] Operation 303: Based on the target ventilation volume, find the corresponding combination among the preset rotational speed combinations of the fans in each ventilation device. For example, find the rotational speed combination of the fan that meets the target ventilation volume in the database;

[0095] Operation 304: Obtain the combination with the lowest noise from the combinations found in Operation 303;

[0096] Operation 305: Adjust the rotational speed of the fan of the corresponding ventilation device according to the combination obtained in Operation 304.

[0097] The above Operations 301 to 305 can be performed cyclically.

[0098] Among them, the preset rotational speed combinations of the fans in each ventilation device involved in Operation 303 can be data obtained through a large number of tests based on the predetermined structural state of the space. For example, the preset combination can be obtained through the following method:

[0099] Adjust the rotational speed of the fan of one ventilation device, while keeping the rotational speeds of the fans of the remaining ventilation devices constant. Conduct actual tests and measurements on the air volume and noise volume within the speed regulation range of the fan of this ventilation device, and record the data in the database. For example:

[0100] Set ① of rotational speed combinations: The rotational speeds of the fans of ventilation devices 201B, 201C, and 201D are kept constant at 1600 rpm. Adjust the rotational speed of the fan of ventilation device 201A, and record the air volume and the corresponding noise volume during the change of the rotational speed of the fan of ventilation device 201A (for example, the corresponding noise volume refers to the noise volume detected at a certain specified position). Thus, multiple rotational speed combinations are obtained, and these multiple rotational speed combinations can be defined as the same set. For example, set ① of rotational speed combinations;

[0101] Set ② of rotational speed combinations: The rotational speed of the fan of ventilation device 201B is kept constant at 1200 rpm, the rotational speeds of the fans of ventilation devices 201C and 201D are kept constant at 1600 rpm. Adjust the rotational speed of the fan of ventilation device 201A, and record the air volume and the corresponding noise volume during the change of the rotational speed of the fan of ventilation device 201A (for example, the corresponding noise volume refers to the noise volume detected at a certain specified position). Thus, multiple rotational speed combinations are obtained, and these multiple rotational speed combinations can be defined as the same set. For example, set ② of rotational speed combinations;

[0102] Set ③ of rotational speed combinations: …

[0103] The rotational speeds of the fans of ventilation devices 201A, 201B, 201C, and 201D can all be independently adjusted (for example, adjust the rotational speed by means of pulse width modulation, or adjust the rotational speed by adjusting the voltage), so as to form a large number of sets of rotational speed combinations, and each set contains multiple rotational speed combinations. Here, only two sets of rotational speed combinations are listed for illustration.

[0104] In this application, taking the air volume as the horizontal axis and the noise volume as the vertical axis, the relationship between the air volume and the noise volume measured under different rotational speed combinations can be plotted in a chart, as Figure 4 shown in the schematic diagram of the relationship between the air volume and the noise volume measured under different rotational speed combinations. In Figure 4 , curve 401 corresponds to set ① of rotational speed combinations, and curve 402 corresponds to set ② of rotational speed combinations.

[0105] For example, if the target air volume is 120 m 3 / h, it can be seen from Figure 4 that the noise value (53 dBA) of curve 402 is smaller. Thus, select the rotational speed combination in set ② of rotational speed combinations with an air volume of 120 m 3The rotation speed combinations corresponding to / h. Further, the rotation speeds of the respective fans of the ventilation devices 201A, 201B, 201C, and 201D at this rotation speed combination are queried from the database.

[0106] It should be noted that the set ① of rotation speed combinations, the set ② of rotation speed combinations, the set ③ of rotation speed combinations, etc. described in Embodiment 1 are all sets of rotation speed combinations for the same position within the space 200. That is to say, for different positions within the space 200, tests can be carried out separately to obtain the rotation speed combinations or sets of rotation speed combinations corresponding to the respective different positions. Among them, the different positions within the space 200 can be represented by the distance between this position and different ventilation devices, or by the relative position relationship between this position and other reference positions within the space (for example, the top or bottom of this space, etc.). When performing operation 303, according to the specified position determined in operation 101, a rotation speed combination that meets the conditions is searched for among the preset rotation speed combinations of the fans of each ventilation device corresponding to this specified position.

[0107] In addition, in the variant of Embodiment 1, multiple rotation speed combinations in the database can also be processed so that, under the same ventilation volume, 1 or several combinations with lower noise are retained. In this way, for the same ventilation volume, the amount of data saved can be reduced, and when in use, selection can be made from these multiple combinations based on user information or other information, and in this way, the control speed can be increased.

[0109] The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the fans of the ventilation devices 201A, 201B, 201C, and 201D are all non-steplessly adjustable fans, for example, fans with fixed operating gears.

[0110] In Embodiment 2, the same method as the method Figure 3 shown can be used to control the noise within the space 200.

[0111] Among them, the preset rotation speed combinations of the fans of each ventilation device involved in operation 303 can be data obtained through a large number of tests based on the predetermined structural state of the space. For example, the preset combination can be obtained through the following method:

[0112] Adjust the rotation speed of the fan of 1 ventilation device (for example, adjust the gear of the fan), and the fans of the remaining ventilation devices all maintain a constant rotation speed. The air volume and noise volume within the speed regulation range of the fan of this ventilation device are actually measured and tested, and the data is recorded in the database. For example:

[0113] Set ① of rotational speed combinations: The rotational speeds of the fans of the ventilation devices 201B, 201C, and 201D are constant at 1600 rpm. Adjust the gear of the fan of the ventilation device 201A to adjust the rotational speed of the fan, and record the ventilation volume and the corresponding noise volume during the change process of the gear of the fan of the ventilation device 201A. Thus, a plurality of rotational speed combinations (i.e., gear combinations) are obtained, and these plurality of rotational speed combinations can be defined as the same set, for example, set ① of rotational speed combinations;

[0114] Set ② of rotational speed combinations: The rotational speed of the fan of the ventilation device 201B is constant at 1200 rpm, and the rotational speeds of the fans of the ventilation devices 201C and 201D are constant at 1600 rpm. Adjust the gear of the fan of the ventilation device 201A to adjust the rotational speed of the fan, and record 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 change process of the gear of the fan of the ventilation device 201A. Thus, a plurality of rotational speed combinations (i.e., gear combinations) are obtained, and these plurality of rotational speed combinations can be defined as the same set, for example, set ② of rotational speed combinations;

[0115] Set ③ of rotational speed combinations: …

[0116] The rotational speeds (e.g., gears) of the fans of the ventilation devices 201A, 201B, 201C, and 201D can all be independently adjusted to form a large number of sets of rotational speed combinations, and each set contains a plurality of rotational speed combinations. Here, only two sets of rotational speed combinations are listed for illustration.

[0117] In this application, taking the ventilation volume as the horizontal axis and the noise volume as the vertical axis, the relationship between the ventilation volume and the noise volume measured under different rotational speed combinations (i.e., gear combinations) can be plotted in a graph, as Figure 5 shown in the schematic diagram of the relationship between the ventilation volume and the noise volume measured under different rotational speed combinations.

[0118] Since the fans of the ventilation devices in Embodiment 2 are non-steplessly adjustable fans, the relationship between the ventilation volume and the noise volume measured under different rotational speed combinations is shown as discrete points in the graph. In Figure 5 it, point 501 corresponds to set ① of rotational speed combinations in Embodiment 2, and point 502 corresponds to set ② of rotational speed combinations in Embodiment 2.

[0119] For example, if the target ventilation volume is 120 m 3 / h, Figure 5 among points 501 and 502, there is no point corresponding to this target ventilation volume. In this case, the target ventilation volume can be adjusted, for example, to make the target ventilation volume fluctuate within a certain range (e.g., 120 - 130 m 3 / h), find the rotational speed combination (i.e., gear combination) with the lowest noise within the adjusted target ventilation volume range. Furthermore, query from the database the rotational speed (i.e., gear) of each fan of the ventilation devices 201A, 201B, 201C, and 201D at this rotational speed combination.

[0120] In addition, for the same content as in Embodiment 1 in Embodiment 2, reference can be made to Embodiment 1 and will not be repeated here.

[0121] It should be noted that in some examples of Embodiment 2 and Embodiment 1, the designated position in this space can be the ear position of the user. For example, the distance between the user's ear and each ventilation device can be used to represent this designated position. Among them, when the posture or position of the user in the space changes, the distance between the user's ear and each ventilation device may change, and thus this designated position also changes.

[0122] Figure 6 is a schematic diagram taking the ear position of the user as the designated position in the space. As Figure 6 shown, in the space 200 inside the soundproof cabin 20, the position where the ear 601 of the user 600 is located is the designated position. Through image recognition or other means, etc., the distances between the ear 601 and each of the fan A, fan B, fan C, and fan D can be detected. Among them, fan A can correspond to Figure 2 the ventilation device 201A, fan B can correspond to Figure 2 the ventilation device 201B, and fan C can correspond to Figure 2 the ventilation device 201D.

[0123] For example, the distance between the ear 601 and fan A is La, the distance between the ear 601 and fan B is Lb, the distance between the ear 601 and fan C is Lc, and the distance between the ear 601 and fan D is Ld.

[0124] It should be noted that Figure 6 the position of fan D in Figure 2 is different from the positions of each ventilation device in Figure 2 . However, the descriptions of each ventilation device in Figure 6 can all be applied to fan D in Figure 6 . In addition, the schematic illustration of the number and position of the fans in

[0125] In at least one example, the distances between the user's ear and each ventilation device (e.g., La, Lb, Lc, Ld) can be stored to represent a specified position in the space. For example, the distances between the user's ear and each ventilation device, the combination of the rotational speeds of the fans of the ventilation devices (or the ventilation volume corresponding to this rotational speed combination), and the noise level at this specified position can be stored correspondingly, thereby reflecting the corresponding relationship among the specified position, the combination of the rotational speeds of the fans of the ventilation devices (or the ventilation volume corresponding to this rotational speed combination), and the noise level at this specified position.

[0126] Embodiment 3

[0127] In Embodiment 3, based on the specified position in the space, the area of the channel for gas exchange between the inside and outside of the space of the static pressure regulating device 204 can be controlled. In Embodiment 3, the number of ventilation devices in the space 200 can be one or more than one.

[0128] In Embodiment 3, the area of the gas exchange channel can be increased in the combination of the rotational speeds of the fans of each ventilation device in Embodiment 1 or Embodiment 2 to form a new combination. For example, the combinations of the rotational speeds of the fans of each ventilation device and the area of the gas exchange channel, as well as data such as the ventilation volume and noise level corresponding to each combination, are pre-stored in the database. Thus, through the target ventilation volume, the combination with the lowest noise level can be selected, and based on this combination, the rotational speeds of the fans of each ventilation device and the area of the gas exchange channel can be adjusted. Among them, the method for adjusting the area of the gas exchange channel can be, for example: adjusting the opening angle of the door or window, adjusting the opening area or opening and closing angle of the valve, etc.

[0129] In Embodiment 3, in combination with the control of the static pressure regulating device, accurate control of the noise level in the space can be further achieved. In addition, the control of the ventilation volume and the noise level can also be taken into account. In addition, regarding Figure 6 the description of the specified position in

[0130] also applies to Embodiment 3.
