Transmission Loss Curve：
Transmission Loss of ZZPIP20G-S acoustics membrane < 1dB @ 1KHz, and < 2.5 dB in the whole frequency range.
NOTE:
(2) The results are tested using a typical digital output MEMS microphone system and self-designed test device in ZZPIP laboratory with representative sample size. The design of the device will affect final performance.
Application：
The membrane could provide the device with immersed waterproof protection and minimal sound transmission loss, keeping the device with the excellent acoustics transmission performance.
Shelf Life：
Note：
All technical information and advice given here is based on ZZPIP's previous experiences and test results. ZZPIP gives this information to the best of its knowledge, but assumes no legal responsibility. Customers are asked to check the suitability and usability in the specific application, since the performance of the product can only be judged when all necessary operating data are available.
