This hearing aid evaluation procedure performed in the otologist's office consisted of three visits: (I) a complete otological examination, an audiological evaluation, and an earmold impression; (2) the dispensing of the earmold and a list of hearing aids that the patient obtains and uses at home; and (3) the evaluation of the efficiency of each hearing aid and the recommendation of the most beneficial aid or aids. For follow up a questionnaire has been sent to each patient seen between November 1966 and April 1970, and it has been found that 97% of those returning the questionnaire were successfully using the recommended aid.
