HC Deb 30 March 1971 vol 814 cc334-5W
Mr. Pavitt

asked the Secretary of State for Social Services what progress has been made on including automatic volume control in Medresco hearing aids and if any of the new models shortly to be produced will include this feature.

Mr. Alison

The Medical Research Council conducted a study into this matter but it produced no conclusive evidence to justify the inclusion of automatic volume control as a standard feature of any Medresco hearing aid.
