Abstract

In a hearing aid and method for automatically switching to a telephone mode, for automatically detecting a telephone situation for the wearer given a binaural supply, the difference between the levels of the input signals of the two hearing devices is measured and compared with at least one threshold value. If the difference in levels drops below or exceeds the threshold value, the respective hearing device is switched to the telephone mode.
