Hearing instrument

摘要

An audio system includes a headset and a portable computing device. The headset includes a first speaker and a first microphone, a second speaker, a second microphone and a processing unit. The first microphone and the second microphone output a first signal and a second signal, respectively. The processing unit combines the first electrical signal and the second electrical signal into a third electrical signal, and communicates the third electrical signal to a portable computing device through an output channel. The portable computing device preferably includes an application that separates the third electrical signal into the first electrical signal and the second electrical signal. The application compensates the first electrical signal and the second electrical signal for a hearing loss of an individual.

1. An audio system, comprising:
a headset and a portable computing device; the headset comprising:
a first speaker and a first microphone, the first microphone outputting a first electrical signal;a second speaker and a second microphone, the second microphone outputting a second electrical signal,a processing unit, the processing unit configured to:
receive the first electrical signal, and the second electrical signal;combine the first electrical signal and the second electrical signal into a third electrical signal; andcommunicate the third electrical signal to a portable computing device through an output channel; the portable computing device being configured to:
separate the third electrical signal into the first electrical signal and the second electrical signal;process the first electrical signal and the second electrical signal to compensate for a hearing loss of an individual of the audio system; andcommunicate the processed first electrical signal to the first speaker through a first channel, and the processed second electrical signal to the second speaker through a second channel, wherein the processing unit combines the first signal and the second signal by:
applying a low pass filter with a first cut-off frequency to the first electrical signal and the second electrical signal;transposing the filtered first electrical signal by a first frequency shift to frequencies above the first cut-off frequency; andadding the transposed first electrical signal and the filtered second electrical signal.
