A hearing device includes: a pinna restorer for provision of a pinna output based on a first pinna input and a second pinna input, wherein the first pinna input is based on a primary first microphone input signal, and wherein the second pinna input is based on a primary second microphone input signal, the pinna restorer comprising: a first filter for provision of a first mixer input based on the first pinna input, a second filter for provision of a second mixer input based on the second pinna input, a first mixer for provision of a first mixer output based on the first mixer input and the second mixer input, and a pinna controller; and an input mixer for provision of an input mixer output based on the pinna output and a secondary mixer input, wherein the secondary mixer input is based on a secondary microphone input signal.

Hearing device with adaptive pinna restoration

The present disclosure relates in a first aspect to a method of detecting speech of incoming sound at a portable communication device. A microphone signal is divided into a plurality of separate frequency band signals from which respective power envelope signals are derived. Onsets of voiced speech of a first frequency band signal are determined based on a first stationary noise power signal and a first clean power signal and onsets of unvoiced speech in a second frequency band signal are determined based on a second stationary noise power signal and second clean power signal.

Method of detecting speech and speech detector for low signal-to-noise ratios

The present disclosure relates to methods of performing bilateral processing of respective microphone signals of a left ear hearing aid and a right ear hearing aid of a binaural hearing aid system and to corresponding binaural hearing aid systems.

Binaural hearing aid system comprising a bilateral beamforming signal output and omnidirectional signal output

A hearing instrument includes a signal processor, and at least two microphones for reception of sound and conversion of the received sound into corresponding electrical sound signals that are input to the signal processor, wherein the signal processor is configured to process the electrical sound signals into a combined signal with a directivity pattern with at least one adaptive null direction &#x3b8;, and wherein the signal processor is further configured to prevent the at least one null direction &#x3b8; from entering a prohibited range of directions, wherein the prohibited range is a function of a parameter of the electrical sound signals.

Hearing instrument with adaptive directional signal processing

An individual with a hearing loss often experiences at least two distinct problems: 1) the hearing loss itself i.e. an increase in hearing threshold level, and 2) a signal-to-noise ratio loss (SNR loss) i.e. a loss of ability to understand high level speech in noise as compared to normal hearing individuals. According to one aspect of the present invention, this problem is solved by selecting parameter values of a noise reduction algorithm or algorithms based on the individual user's SNR loss. Thereby, a degree of restoration/improvement of the SNR of noise-contaminated input signals of the hearing prosthesis has been made dependent on user specific loss data. According to another aspect of the present invention, a hearing prosthesis capable of controlling parameters of a noise reduction algorithms in dependence on the user's current listening environment as recognized and indicated by the environmental classifier has been provided.
