The sensitivity of CRY342 measurement microphone in CRY886-S01 kit is 1.6 mV/Pa, and the noise floor is 40 dB(A). CRY886-S01 coupled cavity kit is used for research, testing and production of acoustic devices, such as hearing aids and headphones.
Standard Compliant:
- Compliance with IEC TS 62886:2016 Hearing aids – Method for measuring electroacoustic performance up to 16kHz
- Compliance with IEC 61094-4:1995 Measurement microphones – Part 4: Specifications for working standard microphones
- Compliance with GB/T 20441.4-2006 Measurement microphones – Part 4: Specifications for working standard microphones
