OSHA Hearing Protection Requirements Decibel Chart

The site foreman handed me the OSHA citation slip last Tuesday, and the first line read something familiar to anyone who’s dealt with noise complaints: failure to maintain hearing conservation program areas where exposure exceeds 85 decibels as an eight-hour time-weighted average. It wasn’t the fine that kept me up at night—it was realizing how often we ignore the math behind the decibel chart until a crew member actually loses their hearing. Most contractors treat noise like background chatter, but the numbers tell a different story about liability and long-term health on your jobsite.

When you’re outfitting a crew of twenty-plus, cost-per-shift matters more than cutting-edge tech. These options balance performance with budget constraints while still meeting OSHA requirements.

Howard Leight Max Volume Reduction System ($12.49 per pair)
Simple foam plugs that deliver NRR of 30 dB—one of the highest ratings on the market without active electronics. The key is proper insertion technique, and the included training cards make this easier than you’d think. At under $15 for a bulk pack, these disappear into your tool rental budget easily. On residential remodels where crews rotate through quickly, speed of deployment matters more than premium features.

Mack’s Soft Fit Earplugs with Volume Control ($8.99 per pair)
The soft silicone tips slide in smoothly without pinching ears after six hours of wear. NRR of 25 dB, and the volume control lets workers adjust comfort levels on the fly. The magnetic charging case doubles as a portable tool organizer—fits inside most truck compartments alongside extension cords and tape measures.
