摘要:
The invention relates to a hearing device 1 adapted for placement in, at or near a person's ear, the hearing device 1 comprising a microphone 2, a receiver 4 and a signal conditioning means 3 connected to the microphone 2 and to the receiver 4, the microphone 2 being arranged for receiving acoustical signals from the person's surroundings 7 and converting these acoustical signals into electrical signals and the receiver 4 being arranged for converting electrical signals into acoustical signals and transmitting these into the ear's ear canal 13. 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.
摘要:
A hearing device having a circuitry unit which is adapted for processing sound signals and converting the processed sound signals into corresponding electrical signals. An output module is provided for receiving the electric signals after processing by the circuitry unit. The output module defines an outer surface. At least one venting channel is arranged adjacent to the outer surface of the output module of the hearing device. The hearing device may also have a mould, which is adapted to receive the output module in a through going opening. The at least one venting channel is arranged at the interface between the mould and the output module and advantageously provides a pressure balance in the user's ear canal to minimize occlusion. An ITE-part of a hearing device is furthermore provided.
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 regards a method for processing audio signals whereby an audio signal is captured, digitized and processed in the digital domain by a digital signal processing unit or DSP, and where a processed output signal from the digital signal processing unit is converted to the analog domain and served at a transducer for providing a sensation of sound. The DSP unit is provided with mean for performing at least two different digital algorithms which delivers each their processed signal having each their non identical time delay and further the most rewarding sound signal is chosen and served at the output transducer.
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.
