  • Methods and apparatuses for setting a hearing aid to an omnidirectional microphone mode or a directional microphone mode
    Patent number: 8396224
    Abstract: The present invention pertains to a method of automatic switching between omnidirectional (OMNI) and directional (DIR) microphone modes in a binaural hearing aid comprising a first microphone system for the provision of a first input signal, a second microphone system for the provision of a second input signal, where the first microphone system is adapted to be placed in or at a first ear of a user, the second microphone system is adapted to be placed in or at a second ear of said user, the method comprising a measurement step, where the spectral and temporal modulations of the first and second input signal are monitored, an evaluation step, where the spectral and temporal modulations of the first and second input signal are evaluated by the calculation of an evaluation index of speech intelligibility for each of said signals, and an operational step, where the microphone mode of the first and the second microphone systems of the binaural hearing aid are selected in dependence of the calculated evaluation ind

  • AUTOMATIC SWITCHING BETWEEN OMNIDIRECTIONAL AND DIRECTIONAL MICROPHONE MODES IN A HEARING AID
    Publication number: 20090304187
    Abstract: The present invention pertains to a method of automatic switching between omnidirectional (OMNI) and directional (DIR) microphone modes in a binaural hearing aid comprising a first microphone system for the provision of a first input signal, a second microphone system for the provision of a second input signal, where the first microphone system is adapted to be placed in or at a first ear of a user, the second microphone system is adapted to be placed in or at a second ear of said user, the method comprising a measurement step, where the spectral and temporal modulations of the first and second input signal are monitored, an C evaluation step, where the spectral and temporal modulations of the first and second input signal are evaluated by the calculation of an evaluation index of speech intelligibility for each of said signals, and an operational step, where the microphone mode of the first and the second microphone systems of the binaural hearing aid are selected in dependence of the calculated evaluation i
