[Check of hearing aid fitting].
A qualified hearing aid fitting is only possible if the ENT doctor not only prescribes the device, but also conscientiously checks the comparative adjustments made by the hearing aid acoustician. In deciding, which of the tested hearing aids achieves the best and most appropriate improvement of hearing, the physician should first thoroughly study the acoustician's fitting protocol, which contains comparative results of all devices tested. The subjective satisfaction of the patient with his hearing aid can be determined in a detailed conversation or with a special questionnaire. The examination of the otoplastic is as necessary as the improvement of speech discrimination under free field conditions, especially with additional noise. With in situ measurement, the individual transmission characteristics of the hearing aid and the otoplastic are tested in a few minutes. Conscientious control of the fitted hearing aid is only possible with loudness scaling. The scaling function shows clearly whether the fitted aid has adequate amplification, is not too loudly adjusted, and whether the field of pleasant hearing has been considered.
