[0002] Open offices are widely used at home and abroad due to their flexible layout, low cost and easy management. However, the diversification of working modes in open offices has put forward the demand for diversification of acoustic environments. When office workers need to work independently, they need the room to have strong speech sound attenuation and low speech clarity to reduce interference; when they need to collaborate in a team, they need the room to have weak speech sound attenuation and high speech clarity to facilitate communication. At present, in order to improve the mutual interference of workers in open offices, the main control methods are to arrange strong sound-absorbing materials in the office, set baffles between workstations and set up masking sound systems. These methods are conducive to independent work of office workers, but not conducive to the needs of team collaboration of office workers.

[0057] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0058] The invention discloses a control method, device, equipment and storage medium for speech sound attenuation in an open office, aiming to solve the problem that a masking sound system cannot match actual needs due to the change of working modes.

[0059] See also Figure 1 The first embodiment of the present invention provides a control method for speech attenuation in an open office, which can be executed by a control device for speech attenuation in an open office (hereinafter referred to as a control device), and in particular, is executed by one or more processors in the control device to implement at least the following steps:

[0060] S101, acquiring office images uploaded by an image acquisition device at preset time intervals, and determining personnel location information based on the office images;

[0061] In this embodiment, the control device can be a terminal with data processing capabilities such as a server, workstation, laptop computer, desktop computer, etc., which can communicate with the image acquisition device, multiple point noise sensors, and the control unit of the movable partition wall in the configured office. The control device can be installed with the corresponding operating system and application software, and the functions required by this embodiment are realized through the combination of the operating system and application software.

[0062] Specifically, in this embodiment, the control device regularly acquires image information in the office through image acquisition devices deployed in the open office. These image acquisition devices can be high-resolution cameras installed on the ceiling or other locations that are conducive to panoramic capture. In order to ensure the real-time nature of the data, the image acquisition device can be set to automatically upload the collected image information at preset intervals. The duration can be adjusted according to the actual situation of the office, which can be between a few seconds and a few minutes.

[0063] When the image information is uploaded to the control device, the control device will process these images and extract the location information of the people in the office. Image processing technology can use image recognition algorithms, which can accurately identify the location of people in the image and convert them into data points stored in the control device. The data points include information such as the specific location of the person, the activity area, and the relative position relationship. Among them, the control device can monitor the distribution of people in the office in real time. It can capture the dynamic changes of the office environment in real time without disturbing the office workers.

[0064] S102, acquiring noise information collected by a plurality of point noise sensors distributed in the office, and determining the working mode of the personnel in the office according to the personnel position information and the noise information, wherein the noise information includes the type and location of the noise source, and the working mode includes an independent working mode, a team collaboration mode, and a mixed working mode;

[0065] Specifically, in this embodiment, multiple point noise sensors are arranged in the open office, which can capture and collect noise information in the office in real time. Noise sensors are installed in key locations in the office area, such as between workstations, meeting areas and near passages, which can comprehensively monitor the noise environment of the entire office.

[0066] When the noise information collected by the noise sensor is uploaded to the control device, the control device will immediately analyze the noise data to determine whether there is continuous speech in the office. If the speech is detected to be continuous, it indicates that there is a conversation or discussion in the office. At this time, the system will further analyze the source location and intensity of the noise. By comparing the source location with the previously collected personnel location information, the control device can determine whether the source of these speech sounds is consistent with a specific person or team.

[0067] If the speech sound detected by the noise sensor is consistent with the location information of the person, the control device will determine that the current office working mode is team collaboration mode. This means that the people in the office are in a collaborative communication state. At this time, it may be necessary to reduce acoustic attenuation and improve speech clarity to facilitate communication.

[0068] If the noise sensor does not detect continuous speech sounds, the control device will determine that the current working mode is independent office mode. In independent office mode, most people need a quiet environment to concentrate on their work. The system will increase the opening of the coupling space to enhance the spatial attenuation of speech sounds and reduce interference between adjacent workstations.

[0069] If the detected speech sound is inconsistent with the personnel location information, the control device will determine that the current working mode is a mixed mode, that is, some personnel may be working independently, while others may be working in a team in a certain area. The control device will dynamically adjust the opening size of the coupling space according to the ratio of the number of people working independently and the number of people working in a team, so that different areas can obtain an acoustic environment that suits their work needs.

[0070] In the first possible implementation of the present invention, it is also possible to first determine whether it is an independent office through a point noise sensor. If it is an independent office, the opening of the coupling space is directly controlled to be maximum. If it is not an independent office, the image acquisition device is called to jointly determine whether the working mode is a team collaboration mode or a mixed mode. These schemes can be selected according to the actual situation and are not specifically limited here, but these schemes are within the protection scope of the present invention.

[0071] S103, controlling the size of the coupling space opening according to the working mode and maximizing the expected factor of language sound attenuation, so that the office language sound attenuation condition is adapted to the working mode, wherein the size of the coupling space opening is controlled based on a movable partition wall configured between the office and its corresponding coupling space.

[0072] Specifically, in this embodiment, when it is determined that the working mode is the independent office mode, the coupling space opening is controlled to be in the largest state, and the sound energy exchange between the coupling space and the office is greatly enhanced, thereby maximizing the spatial attenuation rate of the speech sound (D 2,S ). That is, when sound propagates in the office, the energy will decay rapidly, reducing the sound interference between adjacent workstations, ensuring that independent office workers can work in a quiet environment, improving concentration and work efficiency.

[0073] When it is determined that the working mode is a team collaboration mode, the coupling space opening is controlled to be in a minimum state, the acoustic absorption effect of the coupling space is weakened, and the spatial attenuation rate of speech sound is minimized. Sound can be transmitted more clearly in the office, which is conducive to communication and collaboration between team members.

[0074] When it is determined that the working mode is a mixed working mode, the size of the coupling space opening is determined based on the number of people in the independent office mode and the team collaboration mode, and the maximum expected factor of speech sound attenuation. The expression of the maximum expected factor of speech sound attenuation is:

[0075] ;

[0076] in, For independent office workers, The number of people collaborating in the team, is the minimum spatial attenuation rate of speech sound, which is determined by the minimum opening ratio. is the maximum spatial attenuation rate of speech sound, which is determined by the maximum opening ratio. is the fitting function between the spatial attenuation rate of speech sound and the opening rate, r is the opening rate, and the expression of the opening rate is:

[0077] ;

[0078] in, is the opening area of ​​the coupling space, and S is the surface area of ​​the open office room.

[0079] It should be noted that for the mixed working mode, the control device adopts a more complex and dynamic control method. In this mode, there are both independent office workers who need a quiet environment and team workers who need efficient communication in the office. To this end, the opening size of the coupling space is determined according to the ratio of the number of people in the independent office mode and the team collaboration mode, combined with the maximum expected factor of speech sound attenuation, so that the acoustic environment of the entire office can better meet the needs of independent office and team collaboration.

[0080] The fitting function D(r) between the spatial attenuation rate of speech sound and the opening rate and and , which can be calculated by ODEON acoustic simulation software, where the opening ratio is the input variable and the spatial attenuation rate of speech sound is the output parameter. The fitting function between the spatial attenuation rate of speech sound and the opening ratio is constructed, and the maximum and minimum opening ratios D are calculated. 2, S The value of .

[0081] Spatial attenuation rate D 2, S is the evaluation parameter of speech sound attenuation in open offices, and the spatial attenuation rate of speech sound D 2, S Calculation of sound pressure level of speech sound It is related to the slope of the regression line of the distance r between the sound source and the receiving point. It refers to the attenuation value of the speech sound pressure level for every doubling of the distance between the sound source and the receiving point. A larger value of this parameter means that the open office has a stronger speech sound attenuation. By measuring the speech sound pressure level at each measuring point, the A-weighted sound pressure level at each measuring point is obtained. , and then calculate D by the following formula 2, S The value of:

[0082]

[0083] Where N is the number of measuring points, n is the position number of the measuring point, is the distance between the measuring point n and the sound source, is the A-weighted speech sound pressure level at position n. The specific calculation formula is as follows:

[0084]

[0085] in, is the sound power level of the sound source in frequency band i, is the sound pressure level at the nth measuring point in the ith frequency band, is the sound pressure level in a free field at a distance of 1 m from the standard speech sound source, and takes 52.1, 57.2, 59.8, 53.5, 48.8, 43.8 and 38.6 dB at the 7 octave band frequencies i=125, 250, 500, 1000, 2000, 4000, 8000 Hz respectively. are the A-weighted correction values, which are -16.1, -8.6, -3.2, 0.0, 1.2, 1 and -1.1 dB at the 7 octave band frequencies i=125, 250, 500, 1000, 2000, 4000 and 8000 Hz respectively.

[0086] In this embodiment, the coupling space is configured at the side of the office, or at the top of the office, or at the bottom of the office.

[0087] Take an example to illustrate this embodiment by selecting a typical open office. The selected open office has a space length (span) of 9.0 m, a width (depth) of 9.0 m, an aspect ratio of 1.0, a floor height of 3.8 m, and a total of 23 workstations. There is a coupling space on its side wall, and the coupling dimensions of the coupling space are: length (span) 9.0 m, width (depth) 9.0 m, an aspect ratio of 1.0, and a floor height of 3.8 m. The opening of the coupling space is located on the side wall of the office, and the side wall where the opening is located is a movable partition wall. The maximum opening ratio is 11.0%, and the minimum opening ratio is 0%. Figure 2 shown.

[0088] The voice collection equipment is a point noise sensor, a total of 5, arranged on the workstation desk, 1.2m above the ground. The specific layout is shown in Figure 3 Calculate the fitting function D(r) between the spatial attenuation rate of speech sound and the opening ratio under the open office condition and and , we can get D(r)=0.06r+2.77, .

[0089] Initially, the noise sensor of the open office did not detect the speech sounds in the continuous conversation state, and judged that the working mode was independent office, and the coupling space opening was controlled to be the maximum, that is, r was 11%. At a certain time, the noise sensor detected the speech sounds in the continuous conversation state and generated the sound source location information. Combined with the personnel location information generated by the image acquisition device, the two information were inconsistent, and the working mode was judged to be a mixed working mode. Among them, there were 3 workstations whose image recognition personnel location information and sound source location information were inconsistent, and 20 were consistent. Therefore, it was judged that 3 people were in independent office mode and 20 people were in team collaboration mode. Figure 4 shown.

[0090] When it is determined that the working mode is a mixed working mode, the opening size of the coupling space is determined based on the number of people in independent office mode and team collaboration mode, as well as the expected factor of language sound attenuation. The r value when the expected factor of language sound attenuation is maximized is used as the optimal opening size of the coupling space; combined with the expression of the expected factor of language sound attenuation, it is calculated that when the opening ratio is r=0%, the expected factor of language sound attenuation E takes the maximum value of 0.97. Therefore, the decision coupling space opening ratio changes from 11% to 0%, and the space attenuation rate Changed from 3.33 dB to 2.76 dB.

[0091] In the simulation experiment, an open office acoustic environment simulation model was established, and the effectiveness of the model was verified through actual measurements and comparison with simulation parameter results.

[0092] The open office model has a length (span) of 9.0 m, a width (depth) of 9.0 m, a length-width ratio of 1.0, a floor height of 3.8 m, and a total of 23 workstations. There is a coupling space on its side wall, and the coupling dimensions of the coupling space are: length (span) 9.0 m, width (depth) 9.0 m, a length-width ratio of 1.0, and a floor height of 3.8 m. The coupling space opening is located on the side wall of the office, and the side wall where the opening is located is a movable partition wall, with a maximum opening ratio of 11.0% and a minimum opening ratio of 0%.

[0093] Experiment 1: By changing the opening size of the coupling space, the effect of the coupling space on the attenuation of speech sound in the open office is studied. The change method is to use 1.1% as the step length, and the opening ratio is simulated from 0% to 11%. There are 10 working conditions in total. The experimental results are as follows: Figure 5 As shown, y is the regression line of spatial attenuation rate and aperture ratio.

[0094] As the opening rate increases, the linear regression equation determination coefficient R2 is greater than 0.9, which can better reflect the The trend of increasing with the increase of opening ratio. Compared with the open office with 0% opening ratio of coupling space, As the opening ratio increases to 11%, Increased by 20.7% (0.57 dB).

[0095] Experiment 2: Taking the open office model as the basic model, we changed the location of the coupling space and the opening position to establish three benchmark models as follows: Figure 2 By changing the opening ratio, volume ratio and sound absorption coefficient of the coupling space of the three benchmark models, 90 sets of simulation model data were obtained. The specific parameter settings are shown in Table 1, and the simulation statistical analysis results are shown in Figure 6 .

[0098] Figure 7 Simulation Model The statistical analysis results of the mean, where the hollow stars represent the office without coupling space. Value; error bars represent standard deviation; solid and hollow squares and dotted lines represent significant differences, * indicates significant difference (P<0.05);

[0099] like Figure 7 As shown, compared with the baseline office without coupling space Compared with the coupled space model The analysis of variance (ANOVA) showed that the coupling space opening position (F = 18.53, P < 0.01) had an important effect on This means that when the coupling space parameters change The value of varies depending on the opening position of the coupling space. The pairwise comparison of the least significant difference analysis (LSD) shows that the coupling space with the side wall opening position (3.16 dB) can improve the The standard deviation analysis results show that compared with the floor (0.21) and ceiling (0.18) opening positions, the coupling space with the side wall (0.35) opening position has a better effect on the The impact is greater.
