A demonstration of hearing loss
The Phonak website has a very interesting page on which they demonstrate what it is like to be partially deaf. The page has a number of links that play everyday sounds, such as people talking in various environments, bird song, a piano, a telephone, etc. You can select one of three options for each sound: how it sounds to someone with normal hearing, how it sounds to someone with mild hearing loss and, finally, how it sounds to someone with moderate hearing loss.
I am going to get my Wife to try this. I’ll get her to listen to the sounds for normal hearing first and then the same sounds for a moderate hearing loss. Will be interesting to see her reaction!
