Large space offices and similar spaces in various unitized workstations. Employees in open-plan offices are affected by staff around the station The impact of movement, if the acoustics are poor, can lead to distractions and lack of privacy. Inattention can reduce work efficiency, especially Some of the work that requires high cognitive ability. Poor privacy will not allow confidential or partially confidential conversations. Private conversations may be misunderstood. People hear that this is what the interviewer does not want. The design of an open office space includes the rational placement of staff positions and the mutual position of team members or team members. Open Office Acoustic performance can be affected by indoor sound absorption conditions, partitions and locker heights, background noise, station envelope, station spacing, and room dimensions. The influence of factors. The room's reverberation time was used as the main indicator of its acoustic performance. However, there is evidence that a more comprehensive assessment is required. The price also requires the measurement of other acoustic parameters, such as the spatial attenuation rate of the sound pressure level, the speech transmission index, and the background noise level. If you need to test Reverberation time, according to GB/T 36075.2. This section specifies the measurement method for the open office acoustic performance. Based on the measurement results, it can be calculated to characterize the open office. The individual evaluation of volume acoustic properties. The main goal is to make the stations have good verbal privacy. This measurement method and its derived There is a good correspondence between the individual evaluation value and the staff's acoustic sensation. Placement of furniture has a great influence on the acoustics of the room. Therefore, the measurement should be carried out after the renovation and office furniture layout is completed, without furniture The measurement of the room does not reflect the acoustic conditions felt by the staff. It is also important that measurements are taken indoors in an unoccupied state. If there are people in the room when measuring, the background noise will constantly change, and it is difficult to obtain reliable results. The room should have a normal daytime background Noise, background noise may be generated by ventilation and air conditioning, traffic noise or artificial sound masking systems. The condition represented by the single-valued evaluation amount is that only one person speaks, and the other person does not speak. Therefore, this part uses a single speaker for measurement. If several When people speak at the same time, the masking will increase, making the degree of distraction lessen (see Reference [10]). So, this part of the measurement results Describe what is the most distracting situation. However, this section can also be used to measure the room acoustic quality of places like call centers. Many people at the same time continue to speak in a continuous manner. This sound environment has played an active masking role. This section may underestimate this. Perceived speech private density in class situations. Acoustic indoor acoustic parameters measurement Part 3. Open Office1 ScopeThis part of GB/T 36075 specifies the measurement method of indoor acoustic performance of an open office with office furnishings. Including measurement methods, equipment, test requirements, evaluation methods and expression of results. The measurement results can be used to evaluate the acoustic performance of open offices. This section applies to medium and large open offices.2 Normative referencesThe following documents are indispensable for the application of this document.
