title: [A new method of testing directional hearing (author's transl)].
abstract: Directional hearing is demonstrated by a test in which a model "hears" loudspeaker impulses at known changes of angle. The sounds are recorded and then presented via headphones to listeners. If the subject notices a change he gives a visual signal and the appropriate change of direction is noted by the tester. -In 40 normal hearing test subjects, 20 who were blind recognized more than 50% of changes of direction of 4 degrees, and 20 with normal vision achieved similar success with direction changes of 5 degrees. Utilizing tape recorder and headphones the advantage of this method is its simplicity.
