Abstract
A hearing protector comprises a hearing hood ( 2 ), a microphone ( 7 ), a loudspeaker and an amplifier. The hearing hood ( 2 ) has passive noise damping. The microphone ( 7 ) is disposed exteriorly on the hearing protector, while the loudspeaker is disposed inside the hood. The amplifier amplifies and transmits the signals from the microphone ( 7 ) to the loudspeaker. The noise damping of the hearing hood ( 2 ) is broad band. The frequency range of the amplifier corresponds to the frequency range of human speech. The amplification of the amplifier is variable and the greatest amplification is such that the sum total of the sound levels that are caused, on the one hand, by ambient sound passing through the hood ( 2 ) and, on the other hand, by sound from the loudspeaker amounts to a maximum, predetermined value.
