Wider auditory filters admit excess noise that fully obscures high-frequency formants

Evidence

Wider auditory filters also allow more noise to pass through and obscure spectral contrasts present in sounds. We observe this in the right panel of Figure 3–19, in which the impaired excitation pattern is severely smeared by the presence of the noise, to a much greater extent that the normal-hearing excitation pattern. The two high-frequency formants are essentially completely obscured by the noise. Note that these effects would be further intensified if this simulation included the reduced audibility that is associated with sensorineural hearing loss. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 574
