Title: NOISE SUPPRESSOR AND METHOD OF IMPROVING AUDIO INTELLIGIBILITY
Abstract:
There is provided a noise suppressor 2 comprising a receiver 4 operable to receive an input audio signal 14 and to produce from the input audio signal 14 a first signal 16 and a second signal 18, the input audio signal 14 comprising desired audio and transmission end noise. The noise suppressor 2 further comprises a first processor 6 operable to perform a first process on the first signal 16, the first process comprising noise suppression to remove at least a portion of the transmission end noise from the first signal 16 before outputting the first signal 16 to a first audio channel 10. The noise suppressor further comprises a second processor 8 operable to perform a second process on the second signal 18, the second process comprising outputting the second signal 18 to a second audio channel 12. The first process comprises more aggressive noise suppression than the second process.
