Which type of hearing protection is specifically needed for exposure to 96dB(A) or greater?

When considering hearing protection for exposure to sound levels of 96dB(A) or greater, double hearing protection is recommended. This type of protection combines two forms of hearing conservation solutions to effectively reduce noise exposure.

Double hearing protection typically involves using both earplugs and earmuffs. This approach is essential in environments where sound levels exceed the standard threshold for potentially hazardous noise exposure, which is typically around 85dB(A). In conditions where noise reaches 96dB(A) or higher, the risk of hearing damage significantly increases. Therefore, the combined effect of earplugs (which can reduce noise by a certain number of decibels) and earmuffs offers greater overall attenuation compared to using either method alone.

Thus, when faced with sound levels at or above 96dB(A), using double hearing protection acts as a crucial preventive measure to safeguard against hearing loss in occupational settings, ensuring compliance with occupational health and safety standards.
