I have just received new and better hearing aids. My audiometrist tested my hearing and produced a graph of hearing loss over a number of frequency bands. My new aids were adjusted to amplify the individual bands by an amount necessary to bring them all to the same level. Fantastic result. Why can the same technique not be used with a pair of earphones? It should be possible to design a reasonably compact two channel amplifier with frequency filtering and a series of frequency specific volume controls. This would be plugged into the audio source and the earphones plugged into the amlifier. If the volume controls were calibrated, it could be adjusted either to specifications obtained from ones audiometrist or to personal taste. Any electronics whizz out ther prepared to have a go?
