[A protective hearing aid (author's transl)].
A device consisting of a hearing protector headset and a modified hearing aid is used as a protective hearing aid for normal hearing subjects. Understanding of sufficiently redundant speech is remarkably improved, especially for noise level of about 20 dB above speech level. Tests have been made with the "Freiburger Zahlentest" and amplified "party noise" up to noise levels of 105 dBSPL. As an example: the above mentioned device enables the wearer to understand speech of 85 dB with 105 dB loud speech similar background noise while still the ears are charged with no more than 90 dB at all. Application for hyperacusis and recruitment patients is discussed.
