The construction quality acceptance standards for anechoic chambers mainly include the following aspects:
 
1. Noise control
 
The main purpose of an anechoic chamber is to provide a low-noise environment, therefore noise control is a key part of acceptance. During acceptance, it is necessary to check whether the background noise of the anechoic chamber meets the design requirements. For example, the design of some anechoic chambers requires a background noise level of less than 15dB (A), and there are specific regulations on the allowable deviation values of the sound field within a specific frequency range.
 
2. Acoustic performance testing
 
After the completion of the anechoic chamber, it is necessary to conduct acoustic performance testing and acceptance to ensure that it meets the requirements of acoustic effect. This includes checking the uniformity, reflection, and scattering characteristics of the sound field inside the anechoic chamber.
 
3. Hardware acceptance
 
The hardware acceptance of the anechoic chamber is based on the hardware configuration provisions in the project contract and agreement, and the actual inventory check is conducted to ensure compliance with the regulations. This includes checking whether the structure, materials, dimensions, etc. of the anechoic chamber match the design.
 
4. Construction quality
 
The acceptance of construction quality includes checking the quality control measures during the construction process, the technical skills of construction workers, and the rationality and standardization of operating procedures. In addition, it is necessary to check whether the construction site meets the relevant quality requirements and specifications.
 
5. Security
 
Safety is a factor that must be considered for any building facility. The acceptance of the anechoic chamber also requires checking its safety, including electrical safety, fire safety, etc.
 
The above is the main content of the construction quality acceptance specification for anechoic chambers. These specifications aim to ensure that the anechoic chamber can provide a high-quality acoustic testing environment, while also ensuring the safety and reliability of the construction process and results.
