Ear Simulator
TYPE-2128
Ear Simulator TYPE2128, complying with IEC 60711, is used to measure sound pressure and frequency characteristics of insert type earphone.
Characteristics of ear canal, eardrum, etc., are also taken into account, allowing to measure under similar condition to that with the simulator attached to human ear.
Each product is calibrated with ACO 1/2 inch pressure microphone TYPE7013 associated with dedicated ear coupler.
TYPE2128 is used with standard preamplifier TYPE4028 to realize similar acoustic input impedance to that of human ear, offering really close condition to real ear.
The sound volume can be adjusted in fines, for instance, owing to careful design, precise grind and exact adjustment
