Wearing hearing aids can make users more intensity-sensitive than age-normal hearing peers.

Evidence

Hearing aid users wearing their hearing aid generally showed the same pattern of affect ratings as participants with age-normal hearing, especially for the valence dimension. However, for arousal ratings, those wearing a hearing aid were actually more sensitive to intensity differences than participants in the reference group. This may be because hearing in the reference group was normal for their age, but still implied elevated high-frequency thresholds. Consequently, older adults in the reference group were less sensitive, at least to some acoustic differences, than the hearing aid users. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1377

  • QUESTION: Why would amplification increase sensitivity beyond normal? Is it neural recruitment, or the reference group’s elevated high-frequency thresholds masking differences?
