Abstract
Background: This study aimed to compare the neurophysiological responses to sound in adults with hypersensitivity compared to adults without
hypersensitivity, and correlate the daily-life experiences to the neurophysiological manifestations. Material and Methods: The Adolescent/Adult
Sensory Profile (AASP) was administered to 27 adults, separated by their
cut-off scores. Differences in neurophysiological responses were measured
by N1-P2 Event-Related Potentials (ERP) in response to auditory changes in
frequency and intensity. Reactions to daily sounds were measured by the
hyperacusis questionnaire. Correlations between AASP, hyperacusis questionnaire, and ERP were measured. Results: The basic ability to detect a
change in stimuli manifested in N1 waveform was not significantly different.
However, participants with hypersensitivity presented a stronger P2 response and a higher hyperacusis score. Daily expressions of auditory hypersensitivity correlated (p = 0.05 - p = 0.01) with larger ERP responses. Conclusions: Auditory hypersensitivity as reflected in daily scenarios is evident
in neurophysiological manifestations measured by ERPs. Understanding the
relationship between the neural mechanisms of auditory hypersensitivity
and its daily expressions, may optimize participation and wellbeing for people
with hypersensitivity
