title: The effectiveness of a hearing aid delivery system.
abstract: One hundred and forty-two adult patients had hearing aid evaluation by a modified Carhart technique. Sixty per cent of patients purchased the recommended aid. Reasons for failure to purchase were established by personal contact and by telephone. They are discussed. Open-ended return appointments are recommended for purchasers because subjects have widely varying problems with hearing aids.
