[0035] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0036] It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that in the flowchart. The terms in the specification and claims and the above-described figures are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0037] In the description of the present application, if the first, second, and the like are described for the purpose of distinguishing technical features, they cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the sequence of the indicated technical features.

[0038] In the description of the present application, unless otherwise explicitly limited, the words such as arrangement, installation, connection, etc. should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0039] Noise is the sound emitted when the sound-emitting body vibrates irregularly; any sound that interferes with people's normal rest, study and work, and any sound that interferes with the sound people want to hear is noise; there are many sources of noise, such as car noise on the street, talking in a quiet library, machine noise on a construction site, and too loud TV sound from a neighbor, all of which are noise; when ventilating indoors, the sound produced by the motor working is also noise, especially for isolated rooms, the contaminated gas in the room must be filtered and discharged through a ventilation duct, and the noise produced by the motor is disturbing the rest and life of the isolated population.

[0040] The contaminated gas in the isolated room is filtered and discharged through a ventilation duct, so the motor of the ventilation duct in the isolated room needs to work all the time, and the noise produced by the motor exists all the time, which is disturbing the rest and life of the isolated population.

[0041] As shown in the Figure 1 The indoor noise reduction system according to the embodiment of the present application comprises:

[0042] The sound-emitting module 110 comprises a music vibrating sheet and an air duct.

[0043] The control module 120 is connected with the sound-emitting module 110, and the control module 120 determines the vibrating sheet installation parameters and the sound effect parameters according to the environmental parameters of the indoor environment, wherein the vibrating sheet installation parameters comprise the number and type of the music vibrating sheets, and the sound effect parameters comprise the air flow rate and the music piece; the control module 120 controls the vibration frequency of the music vibrating sheet according to the determined sound effect parameters, so as to form the sound effect matched with the music piece for indoor noise reduction, wherein the music vibrating sheet is installed in the air duct according to the vibrating sheet installation parameters.

[0044] Those skilled in the art can understand that Figure 1The system structure diagram shown in the figure is not a limitation of the embodiments of the present application, and can include more or fewer components, or combine certain components, or different component arrangements.

[0045] In another aspect, various embodiments of the indoor noise reduction method of the present application are proposed.

[0046] Reference Figure 2 According to the indoor noise reduction method of the first aspect of the present application, the method comprises the following steps:

[0047] Step S210, according to the environmental parameters of the indoor, determine the vibration piece installation parameters and the sound effect parameters, the vibration piece installation parameters include the number and type of the music vibration piece, and the sound effect parameters include the air flow rate and the music piece.

[0048] It should be noted that the environmental parameters of the indoor include the size parameters of the room, the temperature and humidity of the room, the air flow rate of the room, and the operating parameters required for the motor to meet the air flow rate; by setting the above parameters, a noisy indoor environment can be simulated by using a three-dimensional modeling software, so that the vibration piece installation parameters and the sound effect parameters of the music vibration piece can be used as independent variables in the simulated indoor environment, and the noise can be used as a dependent variable, and by continuously adjusting the installation parameters and the sound effect parameters, the vibration piece installation parameters and the sound effect parameters that meet the noise requirements can be determined.

[0049] For example, the three-dimensional modeling software uses BIM model software; based on the BIM model, a real indoor environment is simulated: input the size parameters of the room, such as area; and / or, input the temperature and humidity of the room; and / or, input the operating parameters of the motor, such as the current parameters of the motor and / or the speed of the motor; continuously adjust the vibration piece installation parameters of the music vibration piece, judge whether the sound effect generated by the music vibration piece meets the noise reduction requirements, output the vibration piece installation parameters and the sound effect parameters that meet the noise reduction requirements, it should be noted that the number of music vibration pieces affects the size of the sound generated by the music vibration pieces, and the type of music vibration pieces affects the sound effect generated by the music vibration pieces.

[0050] Step S220, according to the sound effect parameters, control the vibration frequency of the music vibration piece, to form a sound effect matching the music piece for indoor noise reduction, wherein the music vibration piece is installed in the air pipe according to the vibration piece installation parameters.

[0051] It should be noted that the sound effect parameters include the air flow rate in the air pipe, in some embodiments, the indoor noise reduction method is applied to an indoor noise reduction platform in an indoor noise reduction system, the indoor noise reduction platform and the motor are in communication connection, and when working, the indoor noise reduction platform controls the air flow rate in the air pipe by controlling the motor, and further controls the vibration frequency of the music vibration piece, so that the music vibration piece generates a corresponding music piece, and indoor noise reduction is achieved.

[0052] For example, refer to Figure 1 In the embodiment shown, the control module 120 includes a motor. The indoor noise reduction platform controls the airflow speed in the duct by controlling the motor, thereby controlling the music vibrator to generate the corresponding music track, thus achieving indoor noise reduction.

[0053] Specifically, in a hotel's debugging and control system, after the indoor noise reduction platform receives a noise reduction command from at least one hotel room, it obtains the corresponding sound effect parameters and vibrator installation parameters for each hotel room through step S210. Based on the vibrator installation parameters, several music vibrators are installed in the air duct connected to the corresponding hotel room. Then, through step S220, the air duct is controlled to reach the corresponding airflow speed. At this time, the airflow speed causes the music vibrators to produce the corresponding music, thereby achieving indoor noise reduction.

[0054] Reference Figure 3 According to some embodiments of the first aspect of this application, step S210, determining the vibrator installation parameters and sound effect parameters of the vibrator based on environmental parameters, includes:

[0055] Step S310: Determine the track based on the audio features generated by the environmental model corresponding to the environmental parameters.

[0056] It should be noted that, for example, BIM modeling software is used to simulate noise in a real indoor environment based on environmental parameters such as room parameters, and tracks that can achieve noise reduction are selected based on the audio characteristics of the noise.

[0057] It should be noted that, in some embodiments, when selecting the installation parameters and sound effect parameters of the music diaphragm based on the BIM model, a plugin can be used to analyze the audio characteristics of the noise, thereby determining the track from the candidate music library based on the audio characteristics; in some embodiments, manual judgment can also be used to select the track by manually judging the audio characteristics.

[0058] Step S320: Obtain the preset installation parameters of the vibrating plate.

[0059] It should be noted that, for example, the installation parameters of the vibrating pad are input into the BIM model software.

[0060] Step S330: Adjust the installation parameters of the vibrator until the audio generated by the vibration of the music vibrator matches the track.

[0061] It should be noted that, for example, based on BIM model software, the installation parameters of the vibrator are adjusted at a pre-set airflow rate until the vibration of the music vibrator can produce audio that matches the selected track.

[0062] Step S340, continuously adjust the air flow rate corresponding to the vibration plate installation parameter, and determine whether the audio generated by the music vibration plate vibration matches the music.

[0063] It should be noted that, for example, based on the BIM model software, when the audio generated by the music vibration plate vibration matches the music, the vibration plate installation parameter of the music vibration plate is determined, and the air flow rate required to reach the audio is determined according to the determined vibration plate installation parameter of the music vibration plate. When the air flow rate in the air pipe cannot be reached, the selection of the music is reselected, and steps S330-S340 are repeatedly executed.

[0064] Step S350, output the vibration plate installation parameter and the sound effect parameter when matching.

[0065] It should be noted that the output noise and the vibration plate installation parameter and the sound effect parameter when matching, at this time in the real indoor environment, the vibration plate is installed according to the vibration plate installation parameter, and the air speed is adjusted according to the sound effect parameter, the music vibration plate can generate the corresponding music, and then realize indoor noise reduction.

[0066] Reference Figure 4 According to some embodiments of the first aspect of the application, step S220, the music vibration plate generates the corresponding music according to the sound effect parameter, comprising:

[0067] Step S410, determining the speed of the motor according to the sound effect parameter, wherein the motor is connected with the air pipe, and the motor is used to adjust the air flow rate in the air pipe.

[0068] It should be noted that in some embodiments, the sound generating module 110 further comprises an air pipe, the sound effect parameter comprises an air flow rate, and the indoor noise reduction platform adjusts the corresponding motor speed according to the air flow rate, while ensuring normal ventilation in the room and reducing the influence of noise on the crowd.

[0069] Step S420, controlling the operation of the motor according to the speed, so that the music vibration plate collides with the flowing air to generate the corresponding music.

[0070] It should be noted that the noise includes the noise generated by the vibration of the air pipe caused by the operation of the motor in the air pipe.

[0071] It should be noted that when the motor is working, the air flowing in the air pipe collides with the music vibration plate at a constant speed, the music vibration plate vibrates at a fixed amplitude and a fixed frequency, and then generates a regular music, which can cover the noise.

[0072] It can be understood that the environmental parameters include indoor temperature, indoor humidity, and indoor wind field data.

[0078] It should be noted that the music vibration pieces are installed in the air duct, and the motor works to make the air flowing in the air duct collide with the music vibration pieces at a constant speed, so that the music vibration pieces generate a regular music, which can cover the noise, and the regular music can reduce the influence of the noise on the crowd while ensuring the normal ventilation of the indoor environment.
