What is an anechoic chamber used for? In what occasions is an anechoic chamber needed?

An anechoic chamber is used to test the noise of a product. It is actually a relatively quiet small room. It can also be said that it is a laboratory for testing sound. It is mainly used to test the sound level of electronic components, household appliances, auto parts, audio equipment and other products. In actual application, if there is no quiet environment, it is impossible to accurately test the noise level of the product, so an anechoic chamber is needed. The background noise in the anechoic chamber is generally below 35dB (A). The background noise refers to the sound level in the anechoic chamber, which is determined by the sound standard of the test product.

So in what occasions is an anechoic chamber generally needed? The first is the production workshop. Because the product needs to be inspected and qualified before it can be shipped, for convenience, the anechoic chamber will be directly installed in the production workshop for testing during production. The second is a special inspection center. In order to detect whether the product meets the standard, the inspection center will also establish a professional anechoic chamber to test and evaluate the product. There are also universities and research centers that will also establish anechoic chambers to conduct research and teach students. In addition to the above situations, there are also occasional ones built in office buildings.

In fact, no matter what occasion it is used in, the function of the anechoic chamber is only one, that is, to isolate the noisy environment and create a quiet acoustic environment that meets the test requirements. The reason why the anechoic chamber is needed is that the existing environment does not meet the test requirements. Now you understand why the anechoic chamber is needed, right?
