General
The Binaural Microphone’s upper section comprises two 2 mm stainless-steel tubes. Because the microphone cables run through the inside of the tubes, either tube can be continuously bent without collapsing, and reshaped to suit test personnel. A miniature coaxial cable in one braid connects Microdot to BNC connectors. Additionally, a cable clip that can be attached to the test subject’s clothing is supplied to relieve pressure on both the microphone’s upper section and the test subject’s ear canal, freeing them from supporting any unnecessary...
