Ear simulator/coupler is a device that simulates the physical characteristics of the human ear. It includes a microphone and an acoustic network with a structure similar to the acoustic characteristics of the human external ear. It is used to make quantitative and qualitative evaluations of the performance of headphone equipment.
CRY711 Ear simulator/coupler
1、Compliance with IEC 60318-4:2010 Occluded - ear simulator for the measurement of earphones coupled to the ear by means of ear inserts
2、Compliance with ITU-T Rec. P.57(2011) Type 2
3、Compliance with SJ/T 10659-1995 Occluded-ear simulator for the measurement of earphones coupled to the ear by ear inserts
Frequency Response Curve of CRY711 Ear Simulator
1、Elaborate design, sophisticated materials and precision manufacturing ensure excellent product consistency.
2、With the built-in CRY372 pressure-field pre-polarization measurement microphone, it can give its performance into full play.
