Summary
Custom uniform attenuation earplugs (UAEs) offered the most consistent hearing protection for musicians, though all tested devices showed significant variability. Fit-testing is crucial for effective sound reduction.
Area of Science:
- Audiology
- Occupational Health
- Music Performance
Background:
- Musicians are exposed to high sound levels, necessitating effective hearing protection.
- Musicians' hearing protection device (HPD) choices are influenced by comfort, effectiveness, and musicality.
Purpose of the Study:
- To evaluate the personal sound attenuation and user perceptions of three HPD types for musicians: foam earplugs, non-custom uniform attenuation earplugs (UAEs), and custom UAEs.
- To compare the consistency and effectiveness of different HPDs in reducing sound exposure for musicians.
Main Methods:
- A mixed-methods study involving 24 musicians.
- Audiometric testing to measure hearing levels with and without HPDs across various frequencies.
- Surveys over six months to assess HPD usage frequency and user perceptions.
Main Results:
- Significant variability in sound attenuation was found across all HPD types.
- Custom UAEs provided the most consistent attenuation across frequencies.
- Musician preferences varied based on instrument and activity; custom UAEs were initially preferred but usage declined over time.
Conclusions:
- Fit-testing is essential for optimizing HPD fit and effectiveness.
- Combining objective performance data with subjective user feedback is key to recommending suitable HPDs for musicians.
- Further research is needed to address the declining usage rates of preferred HPDs.
