title: [Directivity a qualitative function of hearing aids (author's transl)].
abstract: "Directivity" is the name applied by the authors to the overall audioprosthetic phenomena which they have demonstrated in their research into the correction of deficient hearing, using hearing aids equipped with directional microphones. They propose a double blind test in order to attempt to demonstrate objectively the reasons which experimentally and in the Laboratory decide the choice of a hearing aid with a directional microphone or an omni-directional microphone. Amongst other things, the test makes it possible to confirm whether the improvement in intelligibility in a recreated noisy atmosphere is linked or not to the possibilities of directional detection offered by aids equipped with a directional microphone.
