Transmission Loss Curve：
Transmission Loss of AYN-100G20 acoustics membrane < 1dB @ 1KHz, and < 2.5 dB in the whole frequency range.
AYN-100G20-A
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：
