Or reserve a hole

3) The frequence of your DUT(device under test).

4) The shielding effectiveness you need for your DUT(device under test). for example，A weighted sound pressure level:outer white noise 

80dBA, inside noise≤ 40dBA，We can customize acoustic chamber with different isolation degrees according to different requirements, and the background noise is as low as 20-30db

5) Other specific request if you have.

CiTech can specially provide a steady testing environment with noise floor low as 30dBA for performance testing of acoustic products, such as speaker, receiver and mic. Sound isolation can reach more than 40dB(300Hz~20kHz), Also, we can customize sound-isolated box with special size and fixture, and provide integrated testing system solutions.
