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.
一种由听力保护耳机和改良助听器组成的装置被用作正常听力受试者的听力保护助听器。对冗余度足够的语音的理解有了显著改善，特别是对于比语音水平高约20分贝的噪声水平。已经使用“弗莱堡数字测试”进行了测试，并将“派对噪音”放大到105 dBSPL的噪声水平。例如：上述装置使佩戴者能够在105分贝大声语音类似背景噪声的情况下理解85分贝的语音，而耳朵承受的噪声仍不超过90分贝。还讨论了该装置在听觉过敏和重振患者中的应用。
