Hearing device

摘要

A hearing device comprising a first and a second input sound transducers, a processing unit, and an output sound transducer. The first transducer is configured to be arranged in an ear canal or in the ear of the user, to receive acoustical sound signals from the environment and to generate first electrical acoustic signals from the received acoustical sound signals. The second transducer is configured to be arranged behind a pinna or on, behind or at the ear of the user, to receive acoustical sound signals from the environment and to generate second electrical acoustic signals from the received acoustical sound signals. The processing unit is configured to process the first and second electrical acoustic signals. The output sound transducer is configured to be arranged in the ear canal of the user and to generate acoustical output sound signals from electrical acoustic signals.

1. A hearing device configured to be worn in, on, behind, and/or at an ear of a user comprising:
a first input sound transducer configured to be arranged in an ear canal or in the ear of the user, to receive acoustical sound signals from the environment and to generate first electrical acoustic signals based on the received acoustical sound signals; a second input sound transducer configured to be arranged behind a pinna or on/behind or at the ear of the user, to receive acoustical sound signals from the environment and to generate second electrical acoustic signals based on the received acoustical sound signals; a processing unit configured to process the first electrical acoustic signal and the second electrical acoustic signal; and an output sound transducer configured to be arranged in the ear canal of the user,wherein the processing unit is configured to determine a level of the first electrical acoustic signal, a level of the second electrical acoustic signal, and a level difference between the first electrical acoustic signal and second electrical acoustic signal and to use the level difference to process the first electrical acoustic signal and/or second electrical acoustic signal for generating an electrical output acoustical signal,wherein the output sound transducer is configured to generate an acoustical output sound signal based on the electrical output acoustical signal,wherein the hearing device comprises a filter-bank configured to filter each electrical acoustic signal into a number of frequency channels each comprising an electrical sub-band acoustic signal, and wherein the processing unit is configured to determine a level of sound for each electrical sub-band acoustic signal,wherein the processing unit is configured to determine a level difference between the first electrical sub-band acoustic signal and the second electrical sub-band acoustic signal in at least a part of the frequency channels, to convert the level difference into a gain and to apply the gain to at least a part of the electrical sub-band acoustic signals, and
wherein the processing unit is configured to determine whether the level of the first electrical sub-band acoustic signal or the level of the second electrical sub-band acoustic signal is higher, and wherein the processing unit is configured to convert the level difference in a direction-dependent gain that is adapted to amplify the electrical acoustic signal, if the level of the first electrical sub-band acoustic signal is higher than the level of the second electrical sub-band acoustic signal or a combination of the first electrical sub-band acoustic signal and the second electrical sub-band acoustic signal and that is adapted to attenuate the electrical acoustic signal, if the level of the first electrical sub-band acoustic signal is lower than the level of the second electrical sub-band acoustic signal or a combination of the first electrical sub-band acoustic signal and the second electrical sub-band acoustic signal.
