§ 111. Mr. Marquandasked the Minister of Health, as representing the Lord President of the Council, what studies of the effect of noise upon the health of industrial workers have been, or are being, undertaken by the Medical Research Council.
§ Mr. Walker-SmithThe Medical Research Council has during the past 30 years, sponsored studies of the effect of noise in industry; these have been concerned both with the general psychological effects which may be produced and with the more specific effects upon the sense of hearing. At the present time surveys are being undertaken to define the normal deterioration of hearing which occurs with age and the extent to which this may be modified by exposure to industrial noise. These are the studies referred to in the reply given to the right hon. Member on 13th February.
