Hearing-impaired listeners benefit roughly two-thirds less from binaural squelch than normal-hearing listeners.

Evidence

Those listeners who experience deficits in the ability to represent ITD and ILD will also experience deficits with binaural squelch. In Arsenault and Punch’s (1999) evaluation, listeners with hearing loss experienced only 1.7 dB of advantage due to binaural squelch, in contrast to a 4.9 dB advantage experienced by listeners with normal hearing. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1589
