Ergonomic anechoic anti-noise canceling chamber for use with a communication device and related methods
Abstract:
Disclosed, in general, are devices that provide a substantially active noise canceling area over a sound source by causing disruptive interference to all frequency fields of speech sounds from the sound source. In some embodiments, active noise control or active noise cancellation means (“ANC means”) are provided to the device. Said means include one or more active noise canceling speakers for the addition of sound specifically designed to cancel noise from the speech sound source without interfering with the sound source going to the microphone, so the listener can clearly hear what the user is saying.
