Worker Health Protection
Protect your workforce from noise-induced hearing loss with a structured program powered by accurate noise mapping and exposure tracking.
See How It Works →22 million workers are exposed to hazardous noise levels annually. Noise-induced hearing loss (NIHL) is:
OSHA Action Level: At or above this 8-hour TWA exposure, a Hearing Conservation Program is mandatory.
OSHA 29 CFR 1910.95 requires these elements for workers exposed at or above 85 dBA TWA
Initial and periodic noise surveys to identify exposed workers. SoundPLANmanda provides detailed noise maps showing all exposure zones.
Baseline and annual audiograms for exposed workers. Early detection of threshold shifts allows intervention before permanent damage.
Provide appropriate HPDs (earplugs, earmuffs) based on noise levels. Noise maps help select correct NRR ratings for each zone.
Annual training on noise hazards, HPD use, and audiometric results. Visual noise maps make hazard communication more effective.
Maintain noise exposure records, audiograms, and training documentation. SoundPLANmanda generates audit-ready reports automatically.
Review effectiveness annually. Track STS rates, HPD usage, and noise control implementations to continuously improve.
Color-coded maps clearly show hearing hazard areas (>85 dBA) vs safe zones. Post maps at entrances for worker awareness.
Define worker movement paths to calculate personalized 8-hour TWA exposures. Identify who needs to be in your HCP.
Know exact noise levels in each zone to specify appropriate Noise Reduction Rating (NRR) for hearing protectors.
Model noise reduction from barriers, enclosures, or equipment changes. Demonstrate ROI on engineering controls.
Generate reports that satisfy OSHA recordkeeping requirements. Include measurement details, uncertainty, and recommendations.
| Standard | Action Level | Limit Value | Peak |
