That sucks for those of use who have higher frequency loss, especially when the ENT's say hearing aids won't help. But maybe they are looking to do something specific and if it is successful, they will branch out to other types of hearing loss
The normie's hearing loss
4khz drop on the audiogram
The mentally ill perosn's hearing loss
6-14khz muffling doesn't show up on the audiogram until 10k, no one cares about frequencies above 8k.
6k hearing loss is hidden so who cares about my suffering lol
