Noise Monitoring & Hearing Conservation Programs

Noise-induced hearing loss is permanent, common, and entirely preventable — and OSHA requires a hearing conservation program wherever noise exposure reaches the action level. If you have areas where people raise their voices to be heard, you likely have measurable noise exposure.

Noise-induced hearing loss is permanent, common, and entirely preventable — and OSHA requires a hearing conservation program wherever noise exposure reaches the action level. If you have areas where people raise their voices to be heard, you likely have measurable noise exposure.

We measure your actual noise exposure through dosimetry and area monitoring, determine who must be in a hearing conservation program, and build the program — audiometric testing coordination, hearing protection, and training — to meet OSHA's requirements.

What's included

🎧

Noise dosimetry

Personal exposure monitoring across shifts and tasks.

📊

Area noise surveys

Sound-level mapping to identify high-noise zones.

📋

Hearing conservation program

Full program development to 1910.95.

🔇

Control recommendations

Engineering and PPE strategies to reduce exposure.

When you need this

  • You must raise your voice to be heard three feet away in work areas
  • You've never measured noise, or not recently
  • You have no hearing conservation program despite loud operations
  • Employees report ringing in the ears or hearing difficulty
  • You use hearing protection but haven't verified it's adequate
Regulatory context: OSHA's Occupational Noise Exposure standard (29 CFR 1910.95) sets an action level of 85 dBA (8-hr TWA), triggering a hearing conservation program, and a PEL of 90 dBA. The program includes monitoring, audiometric testing, hearing protection, training, and recordkeeping.

Why Vantage

Hearing loss claims are common and expensive, and the program requirements are specific. We measure true personal exposure with dosimetry — not just spot readings — so you know exactly who needs to be in the program and your documentation stands up.

Questions, answered

The rough field test: if you must raise your voice to talk to someone an arm's length away, you're likely near or above the action level. Dosimetry confirms it precisely.

A sound-level meter captures noise at a point in time; a dosimeter rides with a worker across the whole shift to capture true personal exposure. Both have their place; compliance is based on personal exposure.

If any employee is exposed at or above the 85 dBA action level, yes — baseline and annual audiograms are required, and we coordinate that.

Protect hearing before the loss is permanent.
