Semi anechoic chamber

    Anechoic chamber is a kind of precision laboratory for measuring sound power, which usually needs to meet certain conditions, such as background noise, cut-off frequency, free field radius, etc; Zhongke Shengxuan team has solid theoretical foundation and rich practical experience in the field of anechoic chamber. In 2019, it designed and built a - 1 dB semi anechoic chamber in Danyang, Jiangsu Province. In early 2021, it designed and built a - 6.8 DB semi anechoic chamber in Wujiang, Suzhou. The anechoic chamber ranks first in Asia and third in the world.
The semi anechoic chamber is in a closed space, in which one surface is the reflecting surface and the other five surfaces are the full sound absorption surface (the sound absorption coefficient above the cut-off frequency is greater than 99.9%), which is used to accurately test the sound power of the product.
