I searched for an answer to this question without success. Perhaps someone can answer this or point me to an answer.
Once an audiogram has been performed and the selected hearing aid programmed and fitted, real ear messaurents are sometimes (and should) be performed. From this measurement, adjustments are made to the fitting based on how the aid produces sound at the various frequencies as picked up by a microphone inserted in to the ear canal between the receiver and the eardrum.
My question is, once fitted, why not use the fitting software to perform a hearing test much like the initial hearing test that uses headphones? It seems to me that an audiogram created by the wearer pressing a button to indicate when tones generated by a perfectly fitted hearing aid are heard by the wearer would be a better indication of whether the fit has reached its target.
Any audiologist that can comment on this would be much appreciated.
