Ear terminal comprising a sealing section () for arrangement in the meatus () of a human, comprising:

Ear terminal

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.

Ear terminal with microphone for voice pickup

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.

Voice detection and discrimination apparatus and method

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

Ear terminal with microphone for natural voice rendition

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.
