Abstract: A hearing protection device is disclosed which incorporates integrated audiometric testing, thereby allowing for testing without removal of safety hearing protection. The hearing protection is typically intended to be worn for the duration of a work shift, and allows for self-testing during the shift. Embodiments of the device may utilize a series of partial test sessions, so that each test session is kept brief so as to not interfere unduly with the work schedule. This may encourage frequent testing, hopefully aiding in early detection of potential hearing loss. Additionally, methods of use are disclosed.

Abstract: Ear terminal comprising a sealing section (2) for arrangement in the meatus (3) of a human, comprising: an inner microphone (M2) having a sound inlet (S2) for being directed, directed into the meatus, an electronics unit (11) coupled the inner microphone (M2) and also being coupled to a power supply (12) as well as an outer microphone (M1) for measuring acoustic signals in the environment.

Abstract: An ear terminal includes a sealing section arranged for use in the ear meatus of a human, with an inner microphone having a sound inlet for being directed into the meatus and an electronic unit including filtering elements coupled to the inner microphone for filtering the signal from the inner microphone, the filtering elements being programmable to transform the signals based on the sounds received in the ear by the inner microphone into sounds having essentially the characteristics of spoken sounds of the wearer of the ear terminal.

Abstract: An apparatus and a method of voice detection and discrimination apparatus for controlling a voice operated system. A protective ear terminal element in the apparatus protects the ear by providing acoustic attenuation. An inner electroacoustic transducer element on an inner side of the ear terminal element detects a first acoustic field and provides a first electronic signal representing the first acoustic field. An outer electroacoustic transducer element on an outer side of the ear terminal element detects a second acoustic field and provides a second electronic signal representing the second acoustic field. An electronics unit is connected with the electroacoustic transducer elements and includes first and second comparison members.

Abstract: Ear terminal and ear terminal system, in which at least one ear terminal includes a sealing section (2) arranged for use in the ear meatus (3) of a human, including an inner microphone (M2) having a sound inlet (S2) for being directed into the meatus (3); an electronic unit (11) including filtering part coupled to the inner microphone for filtering the signal from the inner microphone (M2), the filtering part being programmable to transform the signals based on the sounds received in the ear by the inner microphone (M2) into sounds when combined with the user's own voice, providing a voice sounding natural to the user.

Abstract: An apparatus and a method of voice detection and discrimination apparatus for controlling a voice operated system. A protective ear terminal element (1,2) in the apparatus protects the ear by providing acoustic attenuation. An inner electroacoustic transducer element (M2) on an inner side of the ear terminal element (1,2) detects a first acoustic field and provides a first electronic signal representing the first acoustic field. An outer electroacoustic transducer element (M1) on an outer side of the ear terminal element (1,2) detects a second acoustic field and provides a second electronic signal representing said second acoustic field. An electronics unit (11,E3) is connected with said electroacoustic transducer elements (M1,M2) and comprises first comparison means (27) for comparison of said first and second electronic signals to obtain the difference between said two electronic signals.

Abstract: Ear protecting device with a sealing section for acoustically sealing the meatus of a human, includes a sound generator with a sound outlet for being directed toward the user meatus; an inner microphone with a sound inlet from the meatus, arranged for measuring the resulting sound field in the meatus; connected to an electronics unit including a sound analyser coupled to the inner microphone, for analyzing sound characteristics of the resulting sound field in the meatus, producing analyzed sound characteristics; storing part in the electronics unit for storing measured predetermined sound characteristics of a properly functioning ear protecting device; a comparing part in the electronics unit for comparing the inner microphone analyzed sound characteristics with the stored measured predetermined sound characteristics; indicating part coupled to the comparing part for being activated if the analyzed sound characteristics differ significantly from the predetermined sound characteristics.

Abstract: Apparatus for therapeutic application of vibro-acoustic energy to a human body, including a closed box with at least one sound opening in which is arranged a loudspeaker directed towards a part of the body. Upholstery is disposed between the box and the body at the location of the loudspeaker and has air passages. Low frequency signals are supplied to the loudspeaker and to one or a plurality of external loudspeakers. Music is supplied to the external loudspeakers. The low frequency signals are influenced either in step with the music, in a predetermined relation to the music, or in predetermined rhythm. As a storage medium for sound there may be used a tape cassette or compact disc in which at least one of the sound channels contains the influenced low frequency signal in the frequency range 30-120 Hz and the remaining sound channels contain pure music.
