Auditory models can isolate single impairment factors that patients cannot
Evidence
The hearing losses observed in patients will commonly involve multiple auditory problems and they will interact in complicated ways that make it difficult to distinguished the effects of any one component of auditory processing. The HI simulator shows how a single factor can be isolated using an auditory model, provided the model is sufficiently detailed. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4045 (

But, all of these potential difficulties apply equally to all of the HI conditions, so it is unlikely that they would affect the results. This suggests that the results truly reflect the role of the loss of compression when listening to speech in everyday environments for people with presbycusis or other forms of hearing impairment. It shows that this new, model-based approach to the simulation of hearing impairment can be used to isolate the compression component of auditory signal processing. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4088 (
