Transmission Loss Curve:
Transmission Loss of ZZPIP-4000WE acoustics membrane < 0.5dB @ 1KHz, and < 1.5 dB in the whole frequency range.

NOTE:
(1) Acoustic Response and IP Grade test part dimension: I.D. 2.0 mm/ O.D. 6.0 mm.
(2) The results are tested using a typical digital output MEMS microphone system and self-designed test device in ZZPIP laboratorywith representative sample size. The design of the device will a fect final performance.
