Artificial Ear/Ear Simulator (IEC 60318-4 coupler with microphone and preamplifier)
Designed for measurements on earphones coupled to the ear by ear inserts such as tubes or ear moulds or eartips見積もり依頼
The Ear Simulator Type 4157 closely reproduces the acoustical parameters of the human ear, presenting the insert earphone under test with an impedance approximating that of the real human ear.
- Frequency response, sensitivity and distortion measurements on insert earphones, e.g. used in hearing aids, operator headsets, etc.
- Servicing of hearing aids
- Production testing of earphones
