HEARING DEVICE WITH PERFORMANCE OPTIMIZED POWER CONSUMPTION FOR VARIABLE CLOCK, VARIABLE SUPPLY VOLTAGE AND VARIABLE DSP PROCESSING PARAMETERS

摘要

The invention relates to a hearing aid with optimized and controllable power consumption. The power consumption is controlled by varying the voltage level of the supply voltage and/or the frequency of the clock signal. Furthermore the invention relates to a method of optimizing the power consumption of a hearing aid, by calibrating its supply voltage and its clock frequency, and the relation between them, according to the production characteristics of the digital signal processor.
