Summary
Loudness perception disturbances in auditory disorders like hyperacusis, dysacusis, and phonophobia are distinct. These conditions, including cochlear hearing loss and facial nerve paralysis, have unique mechanisms and require separate labels.
Area of Science:
- Audiology
- Neuroscience
- Otolaryngology
Background:
- Auditory disorders often present with disturbed loudness perception.
- Terms like hyperacusis, dysacusis, and phonophobia are used interchangeably for these loudness disturbances.
Purpose of the Study:
- To determine if loudness disturbances in various auditory disorders are distinct enough to warrant different labels.
- To compare phenomenological accounts and underlying mechanisms of disturbed loudness perception.
Main Methods:
- Review of scientific literature focusing on phenomenology and testable hypotheses.
- Comparison of hypotheses with experimental and clinical evidence.
Main Results:
- Disturbances in loudness perception vary phenomenologically across different auditory disorders.
- Underlying mechanisms differ between conditions such as cochlear hearing loss, facial nerve paralysis, and central auditory disorders.
Conclusions:
- The current interchangeable labeling of loudness perception disturbances is not justified.
- Distinct labels are needed for disorders with different phenomenological and mechanistic profiles.
