Ear & Mouth Simulators
Type 4153 – Artificial Ear / Ear Simulator (IEC 601318-1 coupler)
Artificial Ear Type 4153 is designed to enable electroacoustical measurements on insert earphones and headphones to be carried out under well defined acoustical conditions. It fulfils the requirements of IEC 60318-1 and has an acoustical impedance basically similar to that of the human ear.
Type 4153 consists of an acoustic coupler, a main housing containing the sockets for the connection of a Brüel & Kjær condenser microphone and a base plate with a mechanism for clamping the object being tested.
- Frequency response and sensitivity measurements on insert earphones and headphones
- Calibration of audiometers
