Itu-t recommendation P.57, Type 2 ear simulation
IEC711 simulation ear technical parameters
Implementation of standard ITU-T P.57 sec.5.2 Type 2 recommendations with IEC60318-4
Frequency range: 100HZ-10khz ±1dB (Simulated human ear impedance)
Frequency range of coupling cavity: 20HZ-16khz (use of coupling cavity)
IEC711 test tool, according to the international standard headset test requirements for precision production, professional factory processing and manufacturing, can test the in-ear type, moving iron, customized headset test. With the standard auricle test, you can also carry out the test of headphone, flat headphone test and other functions. Commonly used functions include sound measurement curves, waterfall charts, sudden attenuation and so on.
