What can hearing aids do for you?
Hearing and understanding are to some extent abilities that we have to learn. If hearing loss means that certain high-frequency sounds, for example, are no longer forwarded to the brain, then the brain gradually forgets how to interpret these sounds. It literally forgets how to hear. Part of the hearing spectrum gets lost.
The history of the hearing aid
Once used exclusively by royal eavesdroppers, hearing aid use has only become popular in the last 200 years. Few people are aware that the first hearing aid for which a patent was registered was worn by Queen Alexandra of England in 1901.
