space layout
The shape and size of an acoustic test chamber has a significant impact on its acoustic performance. Generally speaking, the test room should try to avoid sharp corners and protruding parts to reduce sound reflection and standing wave effects. The ideal layout should be rectangular, which allows for better control over the direction of sound. In addition, the size of the room should also be determined according to the test object and test method to avoid excessive reflection and echo of sound in the room.

Sound insulation treatment
Sound isolation is a key part of acoustic testing room design. Effective soundproofing materials and installation methods can significantly reduce interference from outside noise. Commonly used sound insulation materials include sound insulation panels, sound insulation cotton and sound insulation windows. During installation, attention should be paid to the sealing of joints to prevent sound from leaking through gaps.

Sound absorbing design
The purpose of sound absorption design is to control the reverberation time and sound reflection in the room. Different sound-absorbing materials and arrangements will affect the sound absorption effect. Commonly used sound-absorbing materials include sound-absorbing cotton, sound-absorbing panels and sound-absorbing curtains. When designing, the selection should be based on the size and usage of the room, and should be arranged reasonably to achieve the best sound absorption effect.

Ventilation and air conditioning systems
Ventilation and air conditioning systems are important components of an acoustic testing room. They are not only related to indoor temperature and humidity control, but also affect indoor sound quality. When designing, low-noise equipment should be selected, and appropriate sound insulation and sound absorption measures should be taken to reduce the generation and spread of noise.

lighting design
Lighting design is equally important in acoustic testing rooms. Lighting equipment should be selected and installed to avoid excessive noise and glare that would affect acoustic testing. It is generally recommended to use low-noise LED lights or other low-noise lighting equipment, and ensure that the lighting does not directly illuminate the test object or affect the tester's line of sight.

Door and window design
Doors and windows are one of the main sources of sound leakage. Therefore, the design of doors and windows should focus on their sealing performance and sound insulation effect. It is generally recommended to use double or multi-layer glass doors and windows and use good sealing materials for sealing to reduce sound leakage and intrusion.

Placement of test equipment
The placement of test equipment is critical to obtaining accurate test results. The layout of the equipment should be reasonably arranged according to the test requirements and equipment characteristics to avoid mutual interference. At the same time, the operation and maintenance space of the equipment should also be considered to ensure the convenience of testers' work.

Background noise control
The control of background noise is one of the important aspects of acoustic testing room design. Indoor background noise levels should be controlled in accordance with testing standards and requirements. Commonly used methods include adding sound insulation materials, optimizing ventilation system design, and using sound-absorbing materials.

cost control
Cost control involves reasonable design and material selection on the premise of meeting acoustic performance requirements. A detailed cost list should be developed based on budget and needs, and the costs of each part should be controlled. At the same time, cost savings can also be achieved by optimizing design and selecting cost-effective materials.

construction quality
Construction quality is the key to ensuring the realization of design effects. During the construction process, attention should be paid to details and construction should be carried out in strict accordance with the design drawings and construction specifications. At the same time, strict inspection and acceptance of construction quality should be carried out to ensure that various indicators meet the design requirements.

To sum up, the design points of the acoustic test room cover many aspects and require comprehensive consideration of knowledge in multiple professional fields such as acoustics, architecture, air conditioning, and electrical. Only through comprehensive design and construction can the performance of the acoustic test chamber be ensured to meet various testing needs.
