title: [Hearing aids with distorsion].
abstract: The authors recall how reinforcements of fundamentals and first harmonics produced by differential sounds in old amplifier tube hearing aids were discovered. The authors report the evolution and principles of devices using compensation and coded signals, in order to select low frequency information of the "with distorsion hearing aids". The continuous support of Paul Hennebert in this scope is emphasized.
