Re: Hearing aids power consumption

Although I have no numbers on percentages, the majority of the power consumption is by the digital circuity. I don't know if there are actual percentages or even how they would be calculated.

Dear all,

We all know that hearing-aid batteries run out quickly. I am wondering whether the battery power is mainly consumed by the digital signal-processing circuitry, or by the analog amplifier and receiver? Does anybody know an approximate percentage, say 60% DSP and 40% analog (just my random guess)?
