[The influence of cerebral aging on directional hearing and the indication to applicate a binaural hearing aid (author's transl)].
For demonstrating the influence of cerebral growing old on directional hearing three groups of 20--30 years, 40--50 years and 70--90 years old persons have been tested. It could be shown that the ability to differentiate small changes of direction was diminished, the old persons recognized only changes of 50 degrees and 60 degrees to 100%. The indication to applicate a stereophonic hearing aid has been discussed and the importance to select patients by testing directional hearing for fitting binaural aids is emphasized.
