Abstract:
A method to assess the hearing improvement due to hearing aids is described. This method has been used routinely at a local hospital for 2 years on 200 patients. This method is based on the assessment of the speech reception threshold for sentences ("Marburger Satztest") in silence and in various noise levels (speech simulating noise). The following were used for the assessment of the hearing aid: the improvement of the speech reception threshold in silence with or without a hearing aid, the maximum tolerable noise level (i.e. the noise level at which everyday speech becomes subliminal for patients with hearing aids) and the noise level at which the speech reception threshold with the hearing aid is worse than without.
