Free OSHA compliance tool for safety managers
Monitor workplace noise levels, calculate Time-Weighted Averages, and track dose percentage against OSHA's 90 dBA PEL and 85 dBA action level — all for free in your browser.
Start Monitoring Now →When the 8-hour TWA reaches 85 dBA, employers must implement a Hearing Conservation Program including noise monitoring, audiometric testing, hearing protection, training, and recordkeeping.
DecibelPro alerts you with a yellow warning when this threshold is reached.
The PEL is the maximum allowable 8-hour TWA. Above this level, employers must implement engineering controls, administrative controls, or provide hearing protection. Violations can result in fines up to $15,625.
DecibelPro alerts you with a red warning when this threshold is reached.
Real-time Time-Weighted Average calculation using OSHA's 5 dB exchange rate. See your 8-hour projected exposure at a glance.
Export detailed measurement reports with timestamps, peak levels, averages, and compliance status. Use for preliminary documentation.
Automatic color-coded warnings at 85 dBA (action level) and 90 dBA (PEL). Instant visual feedback when noise levels become hazardous.
An estimated 22 million American workers are exposed to hazardous noise levels each year. These industries have the highest risk:
Stamping presses, grinding, CNC machines, and assembly line operations regularly exceed 90 dB. Workers near punch presses may experience peak levels above 100 dB.
Jackhammers, power saws, pile drivers, and heavy equipment create noise levels that can exceed 100 dB. Variable noise environments make monitoring especially important.
Drilling, blasting, crushing, and conveyor systems in enclosed spaces amplify noise exposure. MSHA has its own noise standards enforced by the Department of Labor.
Concert venues, nightclubs, and sports arenas expose workers to levels that can cause permanent hearing damage. Staff often lack hearing protection programs compared to industrial workers.
