Feasibility studies of evoked response audiometry in the mentally subnormal.
Evoked response audiometry was attempted on a group of seventy-seven unsedated severly subnormal patients up to the age of twenty-two years. Data of some clinical value were obtained in fifty-seven cases. It is suggested that sedation need only be used if the initial attempt at E.R.A. is unsuccessful. Over twenty per cent of the subjects appeared to have significant hearing loss.
