G.R.A.S. 43AA Ear Simulator Kits


The 43AA and 43AA-S2 ear simulator kits both include the ear simulator, a 1/2″ pressure microphone, preamplifier, and testing jig to clamp headset earpieces into for acoustical testing.

The ear simulator is designed to resonate in the same way that the human ear does, which gives accurate results without the need for more expensive and bulky mannequins when performing audiometer calibration or production line testing of headphones or headsets.

These two kits differ in that one comes with an externally polarized microphone, and the other a prepolarized microphone.

They are both built in compliance with ISO-60318-1 & -2.
