For those with a Kingston HyperX Alloy Core RGB Membrane Gaming Keyboard

[Elliot B.]

Have you noticed that, when the backlight is on (either of the two brightnesses), there is a high-pitch whine/hum? (when the room is very quiet)

 

I am 34 and can hear it.

 

As soon as I turn the backlight off, the sound disappears.

 

Very annoying.

Since when does your age differe rather you can hear it or not?

 

Whining normally means a component is out of whack. Compositor or something.

 

If you can live with it being off, yay. Otherwise, get an RMA... (assuming it is still under warranty)

coils and capacitors can whine, you can't just fix it, it requires replacing components, or buy a new keyboard

Many forms of hearing loss are age-related. There are multiple reasons. I think in this case the most relevant detail would be the natural loss of sensitivity to higher frequencies after 20, which indicates that either the noise is rather high in amplitude and high in frequency, or that it's not quite so high-pitched. This page has some plots of typical frequency response vs age.

As you grow older, your ability to hear high frequency deteriorate. It has been used in devices to basically prevent young people from loitering.

All electronics will whine to a certain extent, but a keyboard whine that is loud enough to bother people is rare and probably faulty.

Hell, I lost 60% of my hearing due to Chemo and Radiation.

 

I do, however believe as you get older, it sounds different, BUT... An electrical whine can be heard by many people, but not by age. It's not like "I can hear it at 34, but I can't at 40" There's no base that says "you can hear this at ##".

 

Everyone is different.
