That is a rather unsatisfactory answer. Is it not disturbing that the proposal for an improved body-worn hearing aid has been abandoned after the expenditure of quite considerable sums over a long period? Does not this call into question the whole method by which we attempt to improve these aids under the National Health Service? Will not the Government approach this matter in a radical way? They spend a great deal of time and a considerable amount of money, producing at the end of the day negligible results.
