HC Deb 13 October 1942 vol 383 c1506W
Mr. W. Brown

asked the President of the Bcard of Trade what steps he is taking to ensure that a sufficient supply of the special dry batteries necessary for electrical amplifying valve types of hearing apparatus for the deaf shall be available?

Mr. Dalton

Last year my predecessor arranged that all new hearing aid apparatus should be made to take a standard battery, which could be supplied without undue difficulty, and most existing sets have been converted to use this type of battery. I have now arranged for an increased and improved production of the special batteries required for apparatus, which, for various reasons, cannot be converted.
