asked the Secretary of State for Air what action he has taken to reduce deafness from engine-noise in the aviators and mechanics of his Department, and to ascertain and train the deafened for further service; and whether he will obtain the co-operation of the National Institute for the Deaf in the matter?

Devices to lessen the effect of aircraft noise are provided for all flying personnel and research into the question is continuing. Nerve deafness due to engine noise affects the hearing to a minor degree only and, as cases are detected at an early stage, does not ordinarily result in incapacitation. All flying personnel are examined periodically to assess the condition of their special sense organs, including the ears.

When men are found to be to a certain extent deafened, will the right hon. Gentleman consider having them trained for further service as such training is found to be practical and useful in civil life?

Yes, Sir.
