CRY711 Ear simulator/coupler
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.
1、Compliance with IEC 60318-4:2010 Occluded – ear simulator for the measurement of earphones coupled to the ear using 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.
