ABSTRACT:
The present application relates to a hearing aid, especially a hearing aid with multiple modes of operation and efficient switching between these modes of operation. The hearing aid comprises means for performing a first mode of operation, means for performing a second mode of operation, first and second quality measuring means for providing first and second quality measures corresponding to the first and second modes of operation, respectively, and selecting means for automatically selecting one of said first and second modes of operation by applying a predetermined selection criterion to the first and second quality measures, and wherein the selecting means is programmed to select the mode of operation for which the estimated quality measure is largest when the difference between the first and second quality measures exceeds a predetermined threshold value.
