Abstract
An innovative automatic-noise-reduction headset includes numerous enhancements. For example, one embodiment includes added noise-control circuitry at each of one or more auxiliary inputs to reduce audible hiss in the earcups. Another embodiment includes integrated crossfeed processing circuitry to enhance the spatial imaging of stereo audio perceived by headset users. Still another embodiment provides superior perception of noise cancellation by focusing noise cancelling at midband frequencies, such as 400-800 Hertz, as opposed to just lower frequencies. And another embodiment provides earcups formed of magnesium or a magnesium alloy for improved strength-weight as well as passive noise attenuation in the 400-800 Hertz range.
