CRY6151B Electroacoustic Analyzer

CRY6151B is a robust and reliable electroacoustic analyzer with a frequency range spanning from 20Hz to 20kHz. It is designed to evaluate a diverse array of devices, including USB, Bluetooth®, and noise-canceling headphones; electret, MEMS, and moving-coil microphones; receivers; speakers; Bluetooth loudspeakers; and loudspeaker crossover devices.

Technicians can assess device performance using key metrics and procedures such as sensitivity (SPL), impedance, total harmonic distortion (THD), resonance frequency (F0), headphone balance, headphone positioning, phase, polarity, microphone current and voltage, signal-to-noise ratio (SNR), microphone directivity, speaker Thiele/Small (TS) parameters, and telephone loudness ratings. The CRY6151B offers comprehensive capabilities for thorough and precise evaluation of electroacoustic equipment.

CRY3711 Ear Simulator IEC60318-4

The CRY3711 ear simulator simulates the way an earplug conduit is inserted into the ear canal or auricle to measure headphone performance. It has a 1/2 inch prepolarized pressure field measurement microphone inside and can be used for acoustic testing of high-quality in-ear headphones.

‍The input impedance of CRY3711 is very close to the input impedance of an ordinary human ear, enabling effective measurement up to 10 kHz.
