Broad filters and lost suppression increase masking and blur spectral contrasts.
Evidence
Poor frequency selectivity and loss of suppression would cause listeners with hearing loss to experience more masking and a loss of the important contrasts present in the spectrum. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 569
