Hearing Conservation
Program Management
Protect your workforce from noise-induced hearing loss with a structured program powered by accurate noise mapping and exposure tracking.

Why Hearing Conservation Matters
22 million workers are exposed to hazardous noise levels annually. Noise-induced hearing loss (NIHL) is:
- 100% preventable with proper controls
- Permanent and irreversible once it occurs
- A leading cause of occupational disability claims
- Required by law to be managed through HCPs
85 dBA
OSHA Action Level: At or above this 8-hour TWA exposure, a Hearing Conservation Program is mandatory.
Key Components of a Hearing Conservation Program
OSHA 29 CFR 1910.95 requires these elements for workers exposed at or above 85 dBA TWA
How SoundPLANmanda Supports Your HCP
Visual Noise Zone Identification
Color-coded maps clearly show hearing hazard areas (>85 dBA) vs safe zones. Post maps at entrances for worker awareness.
Individual Exposure Calculation
Define worker movement paths to calculate personalized 8-hour TWA exposures. Identify who needs to be in your HCP.
HPD Selection Support
Know exact noise levels in each zone to specify appropriate Noise Reduction Rating (NRR) for hearing protectors.
Before/After Control Analysis
Model noise reduction from barriers, enclosures, or equipment changes. Demonstrate ROI on engineering controls.
Compliance Documentation
Generate reports that satisfy OSHA recordkeeping requirements. Include measurement details, uncertainty, and recommendations.
