IEC711 318-4 Artificial Ear Occluded Ear Simulator Frequency Response Curve Tester with 3.5mm Cable

IEC711 318-4 Artificial Ear Occluded Ear Simulator Frequency Response Curve Tester with 3.5mm Cable
 
Description:
IEC711 artificial ear is made with reference to the artificial ears for Danish GRAS and BK.

The IEC711 artificial ear uses the IEC-711 human ear simulator as a coupler for acoustical measurements that rely on earbuds to couple the headphones to the human ear.

The following criteria are met:
* IEC 60318-4:2010 Ed.1.0 (formerly IEC 60711): Electroacoustics - Simulators of human head and ear - Part 4: Occluded-ear simulator for the measurement of earphones coupled to the ear by means of ear inserts;
* SJ/T 10659-1995: Occluded-ear simulator for the measurement of earphones coupled to the ear by ear inserts;
* ITU-T Recommendation P.57, Type 2 Ear Simulator

Technical Parameters:
* Implementation standards: ITU–T P.57 sec. 5.2 Type 2 Recommendations and IEC60318-4
* Frequency range: 100Hz-10kHz ±1dB (simulating human ear impedance)
* Coupler frequency range: 20Hz-16kHz (for coupler)

Package Included:
* 1 x Artificial Ear

Packaging Details:
* G.W.: 0.4kg
