Virtual Acoustic Displays for Teleconferencing: Intelligibility Advantage for 'Telephone-Grade' Audio

Virtual Acoustic Displays for Teleconferencing: Intelligibility Advantage for 'Telephone-Grade' Audio

Speech intelligibility was evaluated using a virtual acoustic (3-D audio) display using the method specified by ANSI (S3.2-1989). Ten subjects were evaluated with stimuli either unfiltered or low-pas filtered at 4-kHz. Results show that virtual acoustic techniques are advantageous for both full-band...

description Speech intelligibility was evaluated using a virtual acoustic (3-D audio) display using the method specified by ANSI (S3.2-1989). Ten subjects were evaluated with stimuli either unfiltered or low-pas filtered at 4-kHz. Results show that virtual acoustic techniques are advantageous for both full-bandwidth (44.1-kHz sampling rate) and low-bandwidth (8-kHz sampling rate) 'telephone-grade' teleconferencing systems.
