A method for correct placement of an in-ear communication device, e.g. a hearing aid, in an ear canal of a user, the in-ear communication device comprising an acoustic seal towards inner surfaces of the ear canal and being configured to be located in a bony part of the ear canal during normal operation, comprises: placing the in-ear communication device in the ear canal thereby forming a substantial acoustic seal in the soft part of the ear canal; generating body-conducted sound to inner surface portions of the user's ear canal; gradually inserting the device deeper into the ear canal in the direction towards the ear drum, until a position where the sound level perceived by the user decreases; maintaining the device in this position in the ear canal, this position being the correct position of the device in the bony part of the ear canal. An in-ear device is furthermore provided.

Methods and devices for correct and safe placement of an in-ear communication device in the ear canal of a user

The application relates to a hearing assistance device (HAD) comprising (a) an input transducer system comprising (a1) an audio input transducer (AIT), and (a2) a first supplementary input transducer (SIT), (b) an output transducer (OT) for converting a processed output signal to a stimulus perceivable by said user as sound, and (c) a signal processing unit (SPU) operationally connected to said audio input transducer (AIT), to said first supplementary input transducer (SIT), and to said output transducer (OT), said signal processing unit (SPU) being configured for processing said electric audio input signal, and said first supplementary electric input signal, and for providing said processed output signal. The audio input transducer (AIT) is adapted for being located in an ear of the user. In a NORMAL mode of operation, electric audio input signal is processed in the signal processing unit and the supplementary electric input signal(s) are used to control the processing.

Hearing assistance device comprising an input transducer system

A hearing aid device configured to be partly or fully inserted into the ear canal of a user is disclosed. The hearing aid device comprises a receiver (loudspeaker) adapted to generate and send an air-borne acoustic signal towards the eardrum when the hearing aid device is partly or fully inserted into the ear canal. The hearing aid device further comprises a microphone configured to receive acoustic signals. The hearing aid device comprises a processing unit configured to determine if the hearing aid device is positioned in a correct position in the ear canal on the basis of the acoustic signals received by the microphone.

Hearing aid device with positioning guide and hearing aid device system

In the method according to the invention a signal processing unit receives signals from at least two microphones worn on the user's head, which are processed so as to distinguish as well as possible between the sound from the user's mouth and sounds originating from other sources. The distinction is based on the specific characteristics of the sound field produced by own voice, e.g. near-field effects (proximity, reactive intensity) or the symmetry of the mouth with respect to the user's head.

Method for detection of own voice activity in a communication device

A method for counteracting the occlusion effect of an electronic device delivering an audio signal to the ear, like a hearing aid or an active ear protector, where the electronic device includes a transmission path with an external microphone or input line which receives a signal from the environment and an signal processor and a receiver which receives processes signal from the signal from the signal processor and delivers sound signals to the ear, whereby an ear piece is inserted into the ear canal and totally or partially blocks the canal. The sound conditions in the cavity between the ear piece and the tympanic membrane are directly or indirectly determined, and whenever condition leading to occlusion problems are determined, the transmission characteristics of the transmission path or the receiver changes in order to counteract the occlusion effect.

Method for counteracting the occlusion effects

Method of noise reduction in a hearing aid or a listening device to be used by a hearing impaired person in which the noise reduction is provided primarily in the frequency range wherein the hearing impaired has the smallest hearing loss or the best hearing.
