§ Dr. Stuttafordasked the Secretary of State for Social Services what is the production cost of a transistorised hearing aid; and what is the production cost of a chest type hearing aid.
§ Mr. Alison:National Health Service hearing aids, all of which are transistorrised, are obtained under competitive contracts and it is not the practice to disclose production costs. Experience of purchasing hearing aids for children shows that a head-worn aid is likely to cost about three times as much as a body worn model.
