Question asked today

[studentspark]

I was asked today if turning up the volume on a hearing aid would make the batteries wear down quicker.

I don't know, any thoughts

In any normal audio amplifier turning up the volume will increase the power driven into the loudspeaker and thus the power drawn from the supply, so yes in theory. Almost all amplifier designs also draw some quiescent current when there is no signal present.

At such low power levels as used in a hearing aid I'm not sure how measurable the effect would be in practice.

I wear digital aids in both ears and have quite a high volume setting. The zinc air batteries last around 14 days, give or take.

So I asked a friend and this is what she said: -

The more work the aid has to do, the shorter the battery life. So, hiding on a remote island with no tide or wildlife will enable your aid batteries to last a hell of a lot longer than those of a nightclub hostess who likes to teach toddlers high on E numbers during the day!!!!!!!

She should know as she's worn them most of her life.
