SLC80 Explained
Under AS/NZS 1270:2002, hearing protection is tested for its Sound Level Conversion (SLC80) rating, which indicates the difference between the environmental noise and the sound reaching the wearer’s ears. This rating helps determine the appropriate Class of hearing protection for specific noise levels.
Australian and New Zealand workplaces are obligated under AS/NZS 1269.3:2005 to:
- Conduct noise level surveys to assess exposure (measured as LAeq,8h).
- Provide suitable hearing protection for workers exposed to noise above 85 dB(A).
- Ensure hearing protection is maintained and properly fitted to achieve effective attenuation.
Employers must select hearing protection suitable for the measured noise levels, ensuring compliance with occupational noise management regulations.
