Noise Surveys & Sound Level Mapping — Industrial, Warehouse & Construction

Overview

Onsite noise surveys for industrial facilities, warehouses, construction sites, and more — powered by our proprietary Atlas AI software. Calibrated dosimeters and sound level meters measure every area and worker; Atlas maps the results on a color-coded facility noise map, bands each exposure against the OSHA 85 dBA action level and 90 dBA PEL, and delivers the controls and hearing protection specifications that bring high-noise areas back under control.

Noise Risk, Mapped by Atlas

Occupational hearing loss is permanent, and the regulatory trigger comes earlier than most employers think: at an 85 dBA eight-hour average — not the 90 dBA PEL — OSHA's 29 CFR 1910.95 requires a full hearing conservation program with monitoring, audiometric testing, training, and hearing protection. Yet many facilities have never measured beyond a single spot reading, and a saw station peaking at 109 dB can hide behind a "walk-through seemed fine."

SafetyNet's surveys are different because Atlas turns the measurements into a picture. A certified safety professional measures every area and monitors representative workers through the full shift; Atlas then plots each reading on your facility map in exposure-band colors, charts how dose accumulates hour by hour, computes a single 0–100 risk score, and specifies the minimum NRR per area using OSHA field derating — so the difference between the quiet dock and the over-PEL saw station is visible, quantified, and actionable, not buried in a spreadsheet.

The sources differ — machining bays, conveyor lines, concrete saws — but the discipline is the same: measure with calibrated instruments, band against the OSHA limits, and prescribe controls that fit the environment.

How Atlas Measures Your Noise Exposure

Four measurement disciplines combined into one assessment — the same approach an OSHA compliance officer or industrial hygienist would take, documented to the same standard.

What's Inside Every Report

One document that works for the safety manager, the operations lead, and the crew — a map for communication, banded readings for compliance, and specific controls for execution.

Frequently asked questions

What is a noise survey, and how is it different from sound mapping?

A noise survey is the measurement program: calibrated sound level meter readings per area plus personal dosimetry on representative workers, banded against OSHA's limits. Sound mapping is how the results are presented — Atlas plots every reading as a color-coded pin on your facility map, so the low, moderate, action-level, and over-PEL zones are visible at a glance. SafetyNet delivers both in every noise exposure assessment.

When does OSHA require noise monitoring?

29 CFR 1910.95(d) requires employers to implement a monitoring program whenever information indicates any employee's exposure may equal or exceed an 8-hour time-weighted average of 85 dBA — the action level. At or above that level, the full hearing conservation program applies: audiometric testing, training, hearing protection availability, and recordkeeping. Above the 90 dBA PEL, feasible engineering and administrative controls are required, not just earplugs. A practical rule of thumb: if people must raise their voices to talk at arm's length, you need measurements.

What is Atlas, and what does the AI actually do?

Atlas is SafetyNet's proprietary safety software. For noise surveys, a certified safety professional captures calibrated area readings, timed monitoring, and full-shift dosimetry onsite; Atlas then builds the color-coded facility noise map, bands each exposure against the 85 dBA action level and 90 dBA PEL, charts per-worker dose progression, computes a 0–100 risk score benchmarked against your other assessments, and drafts findings and hierarchy-of-controls recommendations. The assessor reviews and finalizes everything — the AI accelerates the analysis, it doesn't replace professional judgment.

What's the difference between area readings and personal dosimetry?

Area readings measure the sound level at a location — useful for mapping sources and posting requirements. Personal dosimetry measures what an individual worker actually accumulates across the shift as they move through the facility, logged at 2, 4, 6, and 8 hours. OSHA compliance ultimately turns on personal exposure, so dosimetry is essential for workers who rotate between areas or whose tasks vary — a welder may sit below the action level at hour 2 and cross it by hour 6 when grinding starts.

How are hearing protection requirements calculated?

The NRR printed on the package overstates real-world protection, so OSHA applies field derating: subtract 7 from the labeled NRR, then halve the result before subtracting from the measured exposure. Atlas runs that calculation per area and specifies the minimum NRR — and single versus dual protection — needed to bring each worker's protected exposure to 85 dBA or below. For extreme areas, like a saw station peaking over 109 dB, the report calls for earplugs plus earmuffs together.

What happens after the survey?

The report prioritizes engineering controls first — enclosures, damping, isolation, blade and tooling changes — then administrative controls like task rotation and scheduling high-noise work, then hearing protection and hearing conservation program actions for every area at or above 85 dBA. After controls are implemented, we recheck exposures with follow-up dosimetry focused on the highest-risk workers and time windows, so you can document the reduction for OSHA, your insurer, and your workforce.
