Christopher Struck, CJS Labs - San Francisco, CA, USA
The electroacoustics of headsets and other head-worn devices are presented. The Insertion Gain concept is reviewed and appropriate free and diffuse field target responses are detailed. The selection and use of appropriate instrumentation, including ear and mouth simulators, and test manikins appropriate for head-worn devices are described. Boom, close-talking, and noise-canceling microphone tests are shown and practical methods are discussed for obtaining consistent data. Relevant standards are reviewed, typical measurement examples are described, and applications of these methods to analogue, USB, and Bluetooth wireless devices are explained.
