Summary
Hyperacusis, an intolerance to everyday sounds, affects approximately 8% of the population. This condition is linked to concentration issues and sensory sensitivities.
Area of Science:
- Audiology
- Neuroscience
- Psychology
Background:
- Hyperacusis is characterized by an unusual intolerance to ordinary environmental sounds.
- Understanding its prevalence and associated factors is crucial for diagnosis and management.
Purpose of the Study:
- To determine the prevalence of hyperacusis in the general population.
- To explore the descriptive characteristics and associated factors of hyperacusis.
Main Methods:
- A postal survey of a random sample (n=589) and an internet-based survey (n=595) were conducted.
- Data collection methods were compared for potential differences in outcomes.
Main Results:
- Point prevalence rates for hyperacusis were 9% (internet group) and 8% (postal group).
- Excluding participants with hearing impairment yielded rates of 7.7% and 5.9%, respectively.
- No substantial differences were found between data collection methods.
- Hyperacusis correlated with concentration difficulties, use of ear protection, avoidance, tension, and light/color sensitivity.
Conclusions:
- Hyperacusis appears to be a common condition affecting a significant portion of the population.
- The findings highlight the need for increased awareness and research into hyperacusis.
