To test whether the anechoic chamber is qualified, you can take the following methods:

Acoustic test:
Acoustic testing is performed to evaluate the sound attenuation effectiveness of the anechoic chamber. By emitting sound of a specific frequency and intensity inside or outside an anechoic chamber, and then measuring the attenuation and silencing effect of the sound. Commonly used test methods include sound transmission loss test, acoustic absorption coefficient test and acoustic sound insulation performance test. The acoustic test project is the core test project of the anechoic chamber. Most customers build the anechoic chamber just to conduct acoustic testing in the anechoic chamber. Therefore, the anechoic chamber must meet the acoustic test requirements of the product being tested.

Gas flow test:
The design of an anechoic chamber usually takes into account air flow and ventilation to ensure good indoor air quality. Conduct a gas flow test to measure parameters such as air flow velocity, ventilation rate, and gas concentration in the anechoic chamber to evaluate whether the air flow conditions meet the requirements.

Vibration test:
The equipment or machinery in the anechoic chamber may produce vibrations, and the product under test will also vibrate during operation, which will affect the anechoic effect. Therefore, a vibration test is required to measure the vibration level and frequency in the anechoic chamber to evaluate the vibration isolation of the anechoic chamber. Effect.

Temperature and humidity test:
Temperature and humidity within an anechoic chamber are important to the comfort and safety of both equipment and personnel. Conduct a temperature and humidity test to measure the temperature and humidity levels within the anechoic chamber to ensure they are within the appropriate range.

User experience evaluation:
Invite professionals or users into the anechoic room for actual experience and evaluation. They can evaluate the overall effectiveness of the anechoic chamber in terms of listening experience, comfort and ease of use.

The anechoic chamber has a complete set of acceptance test methods and evaluation standards, which can comprehensively evaluate the anechoic chamber's sound attenuation effect, air quality, vibration isolation, temperature and humidity control, and user experience to determine whether the anechoic chamber meets the design requirements and meets the qualification standards. Our professional anechoic chamber manufacturing factories have many years of industry experience and are familiar with customer needs in different industries. We will design and manufacture anechoic chambers according to customer needs. Before handing over to the customer, we will have a detailed on-site acceptance report. According to the customer's requirements, third-party testing agencies are invited to conduct on-site testing and provide third-party testing reports to reassure customers.
