摘要： The invention concerns a hearing aid with at least one primary sound to electric converting transducer converting sounds in the environment into electrical signals and a signal processing unit for amplifying the electrical signal according to the needs of the user and an electrical to sound transducer for receiving the amplified electrical signal and delivering a sound signal to the ear wherein at least one further sound to electrical transducer is provided. The said further transducer has a sensitivity to wind noise which is smaller than the sensitivity to wind noise of the primary transducer and further the signal processing unit has means for detecting the level of wind noise in the signal from the primary sound to electric converting transducer. According to the invention also selecting means are provided for selecting the signal to be amplified from either the primary—or the at least one further sound to electrical transducer.

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.

摘要： The invention concerns a method for counteracting the occlusion effect of an electronic device delivering an audio signal to the ear, like a hearing aid or and active ear protector, where the electronic device comprises a transmission path with an external microphone or input line which receives a signal from the environment and a 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. According to the invention the sound conditions in the cavity between the ear piece and the tympanic membrane are directly or indirectly determined, and whenever conditions leading to occlusion problems are determined, the transmission characteristic of the transmission path to the receiver changes in order to counteract the occlusion effect.
