“…The processing delays in hearing aids and cochlear implants are small in modern devices and certainly within the synchrony window duration shown in this and previous studies (Stone & Moore 1999). In multimedia applications and video communication devices, however, there could still be considerable intermodal asynchrony that cannot be entirely eliminated due to technical limitations (Bloom 1985;Shah & Marshall 1994;Chen et al 1995;Chen & Rao 1998;Finger & Davis 1998;Zonja et al 2006) to the degree that special standards had to be developed. For example, the ITU-T (1990) standard specifies an audio lead and lag of no more than 45 and 125 msecs, respectively.…”

Contrary to either expectation per se, there was no indication of an effect of hearing impairment or age on the sensitivity to intermodal asynchrony in audiovisual speech. It is possible that the negative effects of aging were balanced with the positive effects of increased sensitivity due to reliance on visual cues with hearing impairment. The listeners, normal hearing or hearing impaired, who were more sensitive to asynchrony (with narrower synchrony windows) tended to understand speech in noise better, with both audio-only and audiovisual speech. The practical implication of the results is that delays in audio or video signals of communication systems would affect hearing-impaired listeners in a manner similar to normal-hearing listeners, and due to the importance of visual cues for the hearing-impaired listeners, special attention should be given to limit these delays.

General information on digital signal processing at a reasonably-readable technical level for the non-technical reader may be found in Bloom (1985) and Pohlmann (1991Pohlmann ( , 1992.…”

“…Continuous delay modulations are essential for constructing digital audio effects such as choruses and flangers [17], so that a frame-by-frame MATLAB implementation of these effects should use alternative interpolating functions where the interpolation factor can be prescribed in a local per-sample basis (see e.g. the MAT-LAB function interp1).…”

Abstract-While traditional implementations of variablelength digital delay lines are based on a circular buffer accessed by two pointers, we propose an implementation where a single fractional pointer is used both for read and write operations. On modern general-purpose architectures, the proposed method is nearly as efficient as the popular interpolated circular buffer, and it behaves well for delay-length modulations commonly found in digital audio effects. The physical interpretation of the new implementation shows that it is suitable for simulating tension or density modulations in wave-propagating media.
