BIONIC HEARING HEADSET

摘要

A bionic hearing headset for enhancing directional sound from an external audio source. The headset includes a pair of headphones, each having a microphone array that connects listeners to the environment through a plurality of microphones, even while listening to content presented over the headphones from an electronic audio source. The microphone array signals are first converted into beam-formed directional signals. Diffuse signal components may be suppressed using a common, noise-reduction mask. The audio signals may then be converted to binaural format using a plurality of head-related transfer function (HRTF) pairs.

主权项

1. A headset comprising:
a pair of headphones including a left headphone having a left speaker and a right headphone having a right speaker; a pair of microphone arrays including a left microphone array integrated with the left headphone and a right microphone array integrated with the right headphone, each of the pair of microphone arrays including at least a front microphone and a rear microphone for receiving external audio from an external source; and a digital signal processor configured to receive left and right microphone array signals associated with the external audio, the digital signal processor being further configured to:
generate a pair of directional signals from each of the left and right microphone array signals;suppress diffuse sounds from the pairs of directional signals;apply parametric models of head-related transfer function (HRTF) pairs to each pair of directional signals; andadd HTRF output signals from each pair of HRTF pairs to generate a left headphone output signal and a right headphone output signal.
