asked the Lord President of the Council if, in view of the claims that the National Hearing Aid is superior in performance to any other hearing aid yet made, he will publish, for the information of the deaf public and other interested persons, the results of the National Physical Laboratory performance tests, or any other performance tests carried out on the National Hearing Aid.

Information about this hearing aid, including particulars of performance tests, is given in the report of the Electro Acoustic Committee of the Medical Research Council. This is now in the press and will be issued by His Majesty's Stationery Office in due course.
