Abstract: There is provided a method for measuring in-situ the acoustic attenuation obtained by a hearing protection device worn by a user, comprising: positioning the hearing protection device comprising a microphone oriented towards the user's ear canal at the user's ear; positioning a cup-like measuring device comprising a loudspeaker oriented towards to user's ear and a microphone oriented towards to user's ear at the user's ear in such a manner that a closed space surrounding the hearing protection device is created by the measuring device; providing a test signal via the loudspeaker, capturing audio signals representative of the level of the test signal in the closed space by the microphone of the measuring device and capturing audio signals representative of the level of the test signal in the user's ear canal by the microphone of the hearing protection device; processing the audio signals captured by the microphone of the measuring device and the audio signals captured by the microphone of the hearing protectio

Abstract: There is provided a hearing system comprising: a hearing device to be worn at or in a user's ear for supplying audio signals to said user and comprising a sound attenuation portion for attenuating ambient sound before reaching the user's ear, means for producing audio signals at a controlled level, a loudspeaker which is included in the attenuation portion and which is oriented towards the user's ear canal for providing sound corresponding to the audio signal produced by the audio signal producing means to the user's ear canal, a microphone which is included in the attenuation portion and which is oriented towards the user's ear canal for capturing audio signals from the sound provided by the loudspeaker to the user's ear canal, and a level control unit adapted to control the level of the audio signals produced by the audio signal producing means according to the audio signals captured by the microphone.

Abstract: There is provided a method for monitoring a hearing device comprising an electroacoustic output transducer worn at a user's ear or in a user's ear canal, the method comprising: measuring the electrical impedance of the output transducer; analyzing the measured electrical impedance of the output transducer in order to evaluate the status of the output transducer and/or of an acoustical system cooperating with the output transducer; and outputting a status signal representative of the status of the output transducer and/or of the acoustical system cooperating with the output transducer.
