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 and apply a direction dependent gain. The output sound transducer is configured generate acoustical output sound signals in accordance with the applied direction dependent gain.
Abstract:
A hearing aid is disclosed. The hearing aid comprises a microphone adapted to receive sound signals, an amplifier configured to amplify signals received by the microphone and output means (e.g. a receiver). The hearing aid is configured to detect if speech is received by the microphone and the hearing aid is configured to provide amplification of the detected sound signals according to a non-speech mode when no speech is detected. The hearing aid is configured to provide amplification of the detected sound signals according to a speech mode when speech is detected. The amplification carried out according to the non-speech mode is different from the amplification carried out according to the speech mode. The invention also discloses a method for amplifying sound signals received by a microphone in a hearing aid.
