Noise Level Calculator
Professional noise level calculator for woodworking shops. Calculate decibel levels, exposure limits, hearing protection requirements, and acoustic safety compliance with OSHA standards.
⚠️ HEARING SAFETY NOTICE
Prolonged exposure to high noise levels can cause permanent hearing damage. Follow OSHA guidelines, use appropriate hearing protection, and monitor exposure times. Consult with safety professionals for workplace compliance.

Hearing Protection
Evaluate hearing protection effectiveness and determine appropriate protection levels for different noise environments.
OSHA Compliance
Ensure workplace compliance with OSHA noise exposure standards and implement required hearing conservation programs.
Noise Dose Analysis
Calculate cumulative noise dose exposure to assess risk levels and determine necessary protective measures and controls.
Equipment Assessment
Analyze noise levels from individual woodworking tools and equipment to identify high-risk sources and mitigation strategies.
Frequently Asked Questions
OSHA sets permissible exposure limit (PEL) at 90 dBA for 8-hour time-weighted average. Action level is 85 dBA requiring hearing conservation program. Exposure above 90 dBA requires hearing protection and administrative controls.
TWA = 10 × log₁₀(Σ(Cᵢ/Tᵢ)) where Cᵢ is exposure time at noise level i, and Tᵢ is allowable time at that level. Use 5 dB exchange rate for OSHA calculations (3 dB for NIOSH).
Choose protection based on noise level: Foam earplugs (NRR 25-33) for moderate noise, earmuffs (NRR 20-30) for comfort, dual protection (earplugs + earmuffs) for extreme noise >100 dBA. Ensure proper fit and training.
OSHA requires annual audiometric testing for employees exposed to ≥85 dBA TWA. Noise monitoring should be conducted when equipment changes, new processes are introduced, or employee complaints arise.
Table saw: 85-95 dBA, Router: 95-105 dBA, Planer: 90-100 dBA, Dust collector: 80-90 dBA, Circular saw: 100-110 dBA. Actual levels vary by tool condition, material, and environment.
Noise dose is percentage of allowable daily exposure. 100% dose = PEL (90 dBA for 8 hours). Dose = (C₁/T₁ + C₂/T₂ + ...) × 100%, where C is actual exposure time and T is allowable time at that level.
