Artificial mastoid coupler and additional weight ring. This innovative transducer for bone vibrator testing is a precision mechanical coupler used to calibrate bone conduction hearing aids and audiometer bone vibrators. It provides a simple to use design that 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. Compliant with standards ANSI S3.13-1981(R2007) and IEC 60318-6: 2007.
