TYPE 4157

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
TYPE 4185

Ear Simulator for Telephonometry (ITU-T Type 1 coupler)
Designed for measurements on handset telephones requiring an IEC 60318-1 coupler, including hansets with high ompedance earpiece where sealed conditions are required.
TYPE 4195

Wideband Ear Simulator for Telephonometry (ITU-T Type 3.2 coupler)
Designed for wideband measurements on handset telephones where realistic acoustical loads are needed.
TYPE 4930

Artificial mastoid
Designed for the calibration of bone-conduction hearing aids by simulating the mechanical impedance of human mastoid
TYPES 4227 and 4227-A

Mouth simulator
Designed for testing of telephone transmitters and other microphones where a sound field similar to the human voice field is required
TYPE 4152

Artificial Ear/Ear Simulator (6cc coupler)
Designed to enable electroacoustical measurements on insert earphones and headphones to be carried out under well defined acoustical conditions
TYPE 4946

2 cc click-on coupler
Designed for measurements on all types of hearing aids and is optimized for repetitive use in the laboratory and on the production line. It fulfils the requirements of the ANSI S3.7 (2008) and IEC 60318-5 (2006) standards.
TYPE 4153

Artificial Ear/Ear Simulator (IEC 60318-1 coupler)
Designed to enable electroacoustical measurements on insert earphones and headphones to be carried out under well defined acoustical conditions. Fulfils the requirements of IEC 60318-1 and has an acoustical impedance basically similar to that of the human ear.
