A method for pre-processing a channelized music signal to improve perception and appreciation for a hearing prosthesis recipient. In one example, the channelized music signal is a stereo input signal. A device, such as a handheld device, hearing prosthesis, or audio cable, for example, applies a mask to a stereo input signal to extract a center-mixed component from the stereo signal and outputs an output signal comprised of a weighted combination of the extracted center-mixed component and a residual signal comprising a non-extracted part of the stereo input signal. The center-mixed component may contain components, such as leading vocals and/or drums, preferred by hearing prosthesis recipients relative to other components, such as backing vocals or other instruments.

A hearing assistive device and method of using the same comprising receiving a first audio signal from an ambient microphone, receiving a second audio signal from a directional microphone, mixing the first and second audio signals according to a preference of the first user, and projecting the mixed first and second audio signals into an ear of the first user. The method can further comprise dampening ambient sound arriving directly at the ear by 5-30 decibels, by disposing an occlusive earpiece within the ear to reduce the ambient sound, and projecting the mixed first and second audio signals from a speaker into the ear of the first user to indirectly provide a desired volume of ambient sound to the ear of the first user. The method can further include establishing a group through at least one wireless handheld communication device to facilitate transmission among multiple hearing assistive devices.
摘要:
Es soll ein leistungsstarkes Verfahren zum Schätzen eines Nutzsignals einer Hörvorrichtung und insbesondere eines Hörgeräts beispielsweise zur Störreduktion bereitgestellt wer- den. Dazu wird ein Verfahren vorgeschlagen, bei dem mindestens zwei Mikrofonsignale aus jeweils einem Schallsignal und ein Referenzsignal (n) aus den Mikrofonsignalen (x), bei dem ein Anteil der Mikrofonsignale (x) aus einer vorgebbaren Richtung blockiert ist, gewonnen. Die Mikrofonsignale werden mit einem Filter (FILT) gefiltert, wodurch ein Schätzsignal (S~ q ) erhalten wird. Hierzu wird von Anteilen aus dem Referenzsignal (n) eine Kohärenzgröße (Γ) und aus der Kohärenz- größe eine Leistungsdichtegröße (S) ermittelt. Das Filter wird anhand der Leistungsdichtegröße (S) parametriert.
