Spatial enhancement mode for hearing aids

摘要

Described herein are techniques for artificially enhancing spaciousness in a hearing aid to improve the music listening experience. Such spatial enhancement is produced by doing signal processing in the hearing aid that mimics the acoustic effects of well-designed concert halls. The same techniques can also be applied to improving the experience of listening to recorded music reproduced and amplified over a speaker system, or to music streamed to the direct-audio input of a hearing aid.

主权项

1. A hearing assistance system, comprising:
a first hearing aid comprising an input transducer for converting sound into a first input signal, processing circuitry for filtering and amplifying the first input signal in accordance with specified signal processing parameters to produce a first output signal, and an output transducer for converting the first output signal into sound for a first ear; a second hearing aid comprising an input transducer for converting sound into a second input signal, processing circuitry for filtering and amplifying the second input signal in accordance with specified signal processing parameters to produce a second output signal, and an output transducer for converting the second output signal into sound for a second ear; wherein the processing circuitries of the first and second hearing aids are configured to operate in a spatial enhancement mode that de-correlates the first and second output signals, and wherein the processing circuitries of the first and second hearing aids are configured to pseudo-randomly jitter the phases of the first and second output signals in the spatial enhancement mode.
