• Includes ½ inch 12.5 mV/Pa matched microphone
• Meets IEC 60318-4 and IEC 60711:1981 requirements
• Often referred to as a Series 711 Coupler.

INSERT HEARING AIDS AND EARPHONES

COUPLER MODELS AEC202 & AEC203

• Use AEC202 for ½ inch microphones
• Used for 1 inch microphones
• Both units meet IEC 60126 and IEC 60318‑5 requirements
• AEC202 meets ANSI S3.7 2cc and AEC203 meets ANSI S3.7.

SUPRA-AURAL EARPHONES

NBS 9 A 6CC COUPLER MODEL AEC100

• Designed for 1–inch microphones (not included) and the calibration testing of supra-aural earphones
• Delivers accurate and repeatable measurements up to 8 kHz
• Used for production testing where correlation between the coupler and real ear response is not a requisite.

BONE VIBRATOR TESTS

ARTIFICIAL MASTOID MODEL AMC439C

• The AMC493C artificial mastoid is a precision mechanical coupler used to calibrate bone conduction hearing aids and audiometer bone vibrators. The AMC493C is cost effective and simple to use. Its patented design converts the vibrator force output to an acoustic signal measured with the system’s sound level meter. It is used with the AEC100 coupler or AEC201-A Ear Simulator to perform bone vibrator tests.
