The hardware configuration standards for anechoic chambers mainly include the following aspects:
 
1. Acoustic materials
 
The acoustic materials of the anechoic chamber mainly include sound-absorbing materials and soundproof materials. Sound absorbing materials are commonly used in the treatment of walls, ceilings, and floors to reduce sound reflection and interference. Soundproofing materials are used to prevent external noise from entering the soundproof chamber.
 
2. Testing equipment
 
The testing equipment in the anechoic chamber should meet the requirements of high precision and high stability. This includes sound level meters, microphones, signal generators, data acquisition systems, etc.
 
3. Ventilation and air conditioning system
 
In order to maintain the temperature and humidity inside the soundproof room, it is usually necessary to install ventilation and air conditioning systems. These systems should be designed to be as quiet as possible to avoid affecting the test results.
 
4. Power supply and electrical equipment
 
The power supply and electrical equipment in the soundproof room should meet the requirements of safety and stability. This includes uninterruptible power supply (UPS), regulated power supply, grounding system, etc.
 
5. Safety facilities
 
In order to ensure the safety of the staff, necessary safety facilities should be equipped in the soundproof room. This includes fire extinguishers, emergency exits, emergency lighting, etc.
 
6. Control and monitoring system
 
In order to achieve remote control and real-time monitoring of the anechoic chamber, it is usually necessary to install corresponding control and monitoring systems. This includes monitoring parameters such as temperature, humidity, noise, and remote control of equipment.
 
The above is the main content of the hardware configuration standard for anechoic chambers. These standards aim to ensure that the anechoic chamber can provide a high-quality acoustic testing environment, while also ensuring the accuracy and reliability of the testing process and results.
