Abstract: A method of changing at least two parameter settings of a device includes detecting an abnormal change in an external feedback path and an input signal generated by an abnormal pressure wave, and activating a pressure wave detection switch and an abnormal feedback path detection switch for changing the at least one parameter setting in the device. A device includes a digital signal processor configured to implement a detection algorithm to detect an abnormal change in an external feedback path, an adaptive internal feedback cancellation system for continually monitoring and responsively adapting to changes occurring in an external feedback path, a pattern recognition algorithm for detecting input signals generated when an abnormal pressure wave is generated, at least two parameter settings for adjusting the characteristics of the device, and an abnormal feedback path detection switch for switching the device to a next available parameter setting.
Abstract: An earset microphone includes an earpiece having a wedge portion wherein the wedge portion is positioned between a back side of the ear and a scalp to secure the earpiece in a selected position. A mounting bracket is positioned within the wedge portion. A boom is secured to the mounting bracket and extends from the earpiece such that the boom positions from below an ear lobe towards a mouth of the speaker. A microphone is positioned at the distal end of the boom proximate the speaker's mouth such that the microphone converts the speaker's voice into an electronic signal. An end of a cable is secured to the mounting bracket such that the cable remains secured to the mounting bracket during use and wherein the cable transfers the signal from the microphone to an external component.
