Abstract:
An audio amplification device comprising an electronic module, said electronic-module comprising:(a) a microphone for receiving sound and converting said sound to an input acoustic signal; (b) an analog-to-digital converter coupled to said microphone for converting said input acoustic signal to an input digital signal; (c) a processing core for processing said input digital signal to produce an output digital signal; (d) a digital-to-analog converter coupled to said processing core for converting said output digital signal to an output acoustic signal; (e) a receiver coupled to said digital-to-analog converter for delivering said output acoustic signal to a user; (f) a battery compartment adapted to receive a batter for powering said amplification device; and (g) a volume control operable by said user within a range of volume positions; wherein said electronic module is adapted to emit a reference signal when said volume control reaches a pre-determined volume reserve position in said range, after said volume control is moved from a second volume position in said range to said predetermined volume reserve position.
