Factors in the appreciation of a prosthetic rehabilitation.

6 months after the prescription of a hearing aid, the appreciation of the aid was judged in a group of 160 patients by a questionnaire. The analysis of the answers in combination with the audiometric features is reported. The answers given in a questionnaire have a good interrelation and agree with the score given for the aid. The audiometric features also showed a good correlation for every one but only a weak relation was found with the subjects' appreciations of the aid. The implications of this hearing aid evaluation for the improvement of the fitting procedure are discussed.
