At what decibel level do you need to wear single hearing protection?

• A. 80 decibels
• B. 90 decibels
• C. 95 decibels
• D. 85 decibels

Answer: (D)

Hearing protection is required when noise exposure meets the action level of 85 dBA as an 8-hour Time-Weighted Average. That means 85 decibels is the threshold at which you should wear some form of hearing protection to keep your daily exposure within safe limits and help prevent noise‑induced hearing loss. Using a single layer of protection (like either earplugs or earmuffs) is the minimum you’d use at this level. If the noise is higher or the exposure duration is shorter, you might still protect yourself, and in very loud conditions you may add extra protection or other controls. Levels below 85 dB generally do not require protection under this rule.
