摘要： 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.

摘要： 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.

The object of the present invention is to provide a small, light-weight hearing device 1. The problem is solved in that the receiver 4 comprises a thermoacoustical transducer 18, which allows for a receiver 4 which may take up less space in the hearing device 1 and may have a smaller weight. This has the advantage of allowing the hearing device 1 to be small and light-weight, thus providing an improved wearing comfort. The invention may e.g. be used in hearing aids for compensating a person's loss of hearing capability.
