Subject: Hearing aids power consumption From: Yi-Wen Liu <jacobliu@xxxxxxxx> Date: Wed, 17 Dec 2008 21:09:12 +0000 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--00163616440bd9a509045e447c47 Content-Type: text/plain; charset=ISO-8859-1; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit 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)?
