Fixed presentation levels overestimate hearing-loss effects that sensation-level compensation removes

Evidence

Gallun et al. ( 2013 ) found that the effect of hearing loss on separated thresholds was stronger when one target level was used for all listeners (50 dB SPL) compared to when a sensation level (SL) of 40 dB was used (equivalent to a range of 47–72 dB SPL). They speculated that a broadband increase in gain was not sufficient to combat the non-flat hearing losses of their subjects. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1721
