High Sensitivity to sounds

On the topic of high sensitivity to sounds, my son was recently telling me about something I had never previously heard of, called Coil Whine. He had never heard of it either, until he happened to mention to someone that he is aware of a high-pitched whining sound when he is in the vicinity of rechargeable gadgets that have been fully charged.

There is an article here about the issue and a number of ways to resolve it.

I hadn't heard of this before - an interesting issue.

Thanks for sharing that link Iain .

I've not read the full article, but after recently using my search engine of choice to conduct some brief research, I noticed almost all of the search results seemed to revolve around computers.

In my son's case, he can tell when his mobile phone is fully charged without having to look at it and check. Although he can find the whining sound irritating, it's thankfully not to the extent that it causes him distress.

I must admit that I find his ability to hear when a gadget has been fully recharged to be rather useful.
