The commenter proposes audible coil whine as an explanation for some reports attributed to EHS, describes…

Please research harm from COIL WHINE, high sounds emitted by many electric items including some chargers, airpods, halogen light transformers, some electric bikes, and many others. I believe many people who complain if ehs actually sugger from hearing coil whine, and their central nervous system freaking out. A small percentage of adults with excellent/sensitive hearing like myself can hear this and are very troubled by it, with sleep disruption etc. It gets worse with dental restoration materials like a bridge and white composite filling material as well as eustachian tube dysfunction, which causes the sound to go through jawbone conduction to the inner ear, bypassing muffling in the earcanal, and small fibre neuropathy which means damaged nerve insulation, myelin, causing everything to come in louder and more painful. With so many electric items everywhere this is debliitating. I have suffered since 2019 and finally realise this is coil whine and I can block a lot of the sound wearing Loop Dream earplugs and earmuffs and using acoustic shielding and distance from the items..Worryingly babies and animals can hear this much better too more then most adults. Please save the children (and animals) from coil whine everywhere, including babymonitors like cuboai which people put close to baby. In many cases it is just a cheap product which can be replaced by better. Thank you souch for looking into these things.Wishing you many blessings Moniqueplaisier@outlook.com
