I hate hearing technicians who tell me that because they have programmed my hearing aids to my hearing chart, that I should be able to hear.
The truth is, the hearing tests have such a gap between the tones they measure that there is room for infinite variation between the points they then plot on the graph. And it is between these points that clarity disappears.
When will someone invent a hearing test that truly does test hearing as it is heard – or not – by the person being tested? Without this, the resulting programming of hearing aids cannot be anything other than primitive guesswork. And who suffers? The hearing aid user. And where can they go for help? Only back to the person who tested them on inadequate equipment in the first place.

So a plea, for a sophisticated sound testing system which maps on a detailed scale, and not just tones but words – for hearing a sound is not the same as distinguishing a word in speech, as anyone with a hearing problem will tell you!
Can any one of you techies harness the impressive sound and eavesdropping equipment available to the music industry and spooks for us with imperfect hearing?
