High Sensitivity to sounds

Homebird

It's that time of the year when we get fireworks for about 4 weeks. I just jumped after an extremely loud bang. This is the second time recently. I am now dreading the nights when all is quiet and I just get to that stage where I am about to drop off to sleep, only to be suddenly wide awake at a bang. It seems like they are louder than they used to be.

  • 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.

    I used to find lots of electronics squealed. TVs annoyed me the most. The tone can change depending on what it's doing.

    Cheap power supplies do it.

    Is it a plug in usb charger, or a wireless charging pad? Or both?

    I thought it had got better but perhaps it's just I am getting older and don't hear as well any more.

    The charging cable for my son's mobile phone has a plug. To be clear, the coil whine thing he experiences isn't a new thing that he's just suddenly become aware of.

    In addition to my son's mobile phone, I have items with plug-in USB chargers. He can hear when they have been fully-charged, but I can't. For years I thought he was having auditory hallucinations, or that I was possibly becoming hard of hearing.

    It's a harmonic of the switch mode power supplies, it changes when the load changes due to charging finishing. Some are noisier than others.

    It's a real thing. You need sensitive hearing in the higher frequencies.

    Years ago I used to complain about the frequency response of certain mobile phon headsets and speakers, and I wondered why no-one else I worked with could hear it.
