With the rapid development of electronic technology, a series of headphones with novel shapes and excellent performance have come into the view of the public. In recent years, the public has become increasingly demanding of noise cancellation performance, and the market for ANC headphones has grown rapidly. The increase in demand naturally requires more supply. At the same time, as the traditional ANC headphone testing process is cumbersome, and its operation is difficult and inefficient, the use of efficient automated test methods can improve efficiency significantly. Our ANC headphone auto-calibration test solution cancels the tedious manual gain deb ing steps, leads to stable and reliable test results, and reliably ensures product quality.

CRY6151B Electroacoustic analysis system
CRY6151B electroacoustic analyzer is the newest electro-acoustic analyzer with powerful functions and strong stability. It can measure the performance of headset(USB, Bluetooth, ANC), microphone(electret, dynamic, and MEMS), receiver, micro speaker, loudspeaker, communication helmet, etc. The measurement parameters include frequency response, sensitivity, impedance, distortion, resonant frequency(F0), balance, the position of headphones, phase polarity, current and voltage of microphone, signal to noise ratio(SNR), directivity, T&S parameters, loudness rating, and so on.
CRY6151B is a full-featured electroacoustic device tester newly launched by CRY Sound. It is powerful and stable. It can measure the performance indicators of headphones (USB, Bluetooth, anti-noise), microphones (electret, MEMS, moving-coil type), headphone and microphone assemblies, receivers/headphone speakers, speakers/loudspeakers (common, Bluetooth), loudspeaker crossover devices, and other electroacoustic devices, such as sensitivity (SPL), impedance, distortion (THD), resonance frequency F0, left and right headphone balance, left and right headphone position, phase polarity, microphone current and voltage, SNR, microphone directivity, speaker's TS parameters, telephone receiving and sending loudness ratings, etc. Its test frequency range can be up to 20 Hz - 20 kHz.
Hardware
1、CRY6151B has high-performance hardware scalable for synchronous 8-channel acquisition/4-channel output.
2、Its hardware includes a sound card module, power amplifier module, signal processing module, USB communication module. It is combined with software to perform various electroacoustic device tests.
3、Its compact chassis design and simple USB data communication method can meet customers’ various test environment requirements.
Software
1、CRY6151 V8.X supports WinXP, Windows 7, and Windows 10 (32 & 64-bit) systems (corresponding drivers to be installed. It is necessary to inform the specific operating environment). It has a user-friendly interface and powerful operation functions.
2、It supports a variety of sweep methods, including effective value, fast-stepping sweep, high precision stepping sweep, multi-tone test, white noise, pink noise, etc. Choose different methods according to different test occasions and test needs.
3、The frequency response, sensitivity (SPL), distortion, impedance, F0, phase, balance, polarity, and other parameters can be measured and determined in one sweep, with the higher test accuracy and faster speed.
4、It is the earliest domestic instrument that can test Bluetooth audio. It is automatically paired without a manual click.
5、It has a powerful sequence editing function, virtual signal generator, multimeter, and complete storage function so that it is fully suitable for customers’ applications in laboratories and production lines.
