“…However, music, and especially live music, can have a wide dynamic range (Chasin and Hockley, 2014). WDRC is a practical way of making it possible for a person with loudness recruitment to hear weak sounds without intense sounds becoming uncomfortably loud, although hearing aids often are not completely successful in achieving this for music (Madsen and Moore, 2014b).…”

The effects of wide-dynamic-range compression (WDRC) on the ability of hearing-impaired subjects to hear out individual instruments or voices (called "sources") in a mixture were explored. On each trial, the subjects were asked to judge the relative clarity of the target in two repetitions of the same music excerpt (mixture of sources) that were processed in different ways. The stimuli were processed via a five-channel simulated WDRC hearing aid, using individual insertion gains and compression ratios recommended by the CAM2 fitting procedure. Both fast- and slow-acting WDRC and a condition with linear amplification and frequency-response shaping were used. To investigate the role of cross-modulation (the partial correlation of the envelopes of different sources caused by the time-varying gain applied by the compressor), conditions were included where the sounds from different sources were compressed before being added together and where the sounds were added together before being compressed. The results showed no effect of cross-modulation, lower clarity with WDRC than with linear amplification, and no significant overall effect of compression speed, although some subjects consistently rated clarity as greater with slow compression. The deleterious effect of WDRC may be related to changes in temporal-envelope shape or reduced spectral contrast produced by WDRC.

“…In music therapy, the positive effects of musical interventions on children with hearing loss have been described [32,33]. Much of the recent research on music with hearing loss has focused on the emerging technologies related to cochlear implants, while some studies look particularly at hearing loss with just hearing aids, such as in the description of how people with hearing aids listen to music from an audiological perspective [34,35]. Music perception by cochlear implant users has been observed both by otolaryngology laboratories [36][37][38] and by psychologists' groups [39,40].…”

Abstract:We conducted an experiment using a purposefully designed audio-based game called the Music Puzzle with Japanese university students with different levels of hearing acuity and experience with music in order to determine the effects of these factors on solving such games. A group of hearing-impaired students (n = 12) was compared with two hearing control groups with the additional characteristic of having high (n = 12) or low (n = 12) engagement in musical activities. The game was played with three sound sets or modes; speech, music, and a mix of the two. The results showed that people with hearing loss had longer processing times for sounds when playing the game. Solving the game task in the speech mode was found particularly difficult for the group with hearing loss, and while they found the game difficult in general, they expressed a fondness for the game and a preference for music. Participants with less musical experience showed difficulties in playing the game with musical material. We were able to explain the impacts of hearing acuity and musical experience; furthermore, we can promote this kind of tool as a viable way to train hearing by focused listening to sound, particularly with music.

“…(8) When the AGC is very fast-acting, it can introduce harmonic and intermodulation distortion [59]. However, the AGC can be designed to minimize the perceptual effects of such distortion [54], and in practice harmonic and intermodulation distortion are not usually a significant problem in commercial hearing aids [50], except perhaps for very high input and output levels [60,61].…”

“…Chasin [60] has argued that distortion in hearing aids for high input signal levels occurs mainly because of the limited dynamic range that can be handled by current ADCs.…”
