Description

0.4 cc coupled cavity, resonant frequency = 30 kHz CRY886-S01 is a high-frequency coupler kit for testing hearing aids with frequency up to 16 kHz. The coupled cavity increases the resonance frequency to 30 kHz, so it does not interfere with measurements within the audio range. The volume of the coupled cavity is 0.4 CC. 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. Reusable Resistant to harsh environments Wide range of applications 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 CRY342 Measurement Microphone is a pre-polarization 1/4'' pressure-field type condenser measurement microphone. Due to its low sensitivity, it is mainly used for high sound pressure and high frequency measurements. It can measure sound pressure levels up to 168 dB. Titanium film can achieve high stability and high accuracy in harsh environments. CRY547 Preamplifier can be used with a 1/4'' measurement microphone to convert impedance. This preamplifier has high input impedance, low output impedance, low noise, wide frequency response range and other characteristics. It can be used for electroacoustic test systems or multi-noise analysis.
