Hearing Conservation for
Distilling, Bottling & Warehousing.
Bottling lines hit 105 dBA. Mill rooms run continuous. Stillhouses run hot. Soundtrace fits hearing conservation into the rhythm of distillery production — without disrupting it.

The Reality on the Floor
Why Distilleries Fall Behind on Hearing Conservation
Craft growth, bottling-line throughput, and multi-room exposure paths break the assumptions a single annual van program was built around.
Bottling Lines Are the Loudest Room in the Distillery
High-speed glass-on-glass bottling, capping, and labeling lines run 92–105 dBA throughout an entire shift. Many craft and mid-sized distilleries have never conducted formal dosimetry here.
Mill, Mash & Still Rooms Add Continuous Exposure
Hammer mills for grain reduction, agitated mash tuns, and steam-driven stills run hot and loud. Workers move between these areas all shift, accumulating exposure across multiple zones.
Barrel Warehouses Hide Forklift & Racking Noise
Rickhouses run quieter on average — but forklift traffic, dunnage handling, and bottling-tied transfer pumps push exposure above 90 dBA in working areas. Cooper rooms add another spike.
TTB, FDA & OSHA Stack on the Same Production Floor
TTB inspections, FDA FSMA reviews (for flavored spirits and RTDs), and OSHA visits often hit during the same production season. Incomplete hearing conservation records compound across audits.
Built for Your Operations
How Soundtrace Fits Into Distilling
Test During Bottling Runs
6 min
per test
6-minute in-house audiograms slot into shift changes on the bottling line. Catch STS early instead of waiting for the next van visit.
Baseline Production Hires Day One
Day 1
baseline captured
Stillhouse operators, bottling-line crews, and warehouse staff get baseline audiograms before they hit the floor — no waiting for an annual van schedule.
Verify HPD on the Bottling Line and in the Mill Room
Real
NRR verification
Fit testing measures actual attenuation in 96+ dBA bottling rooms and dusty mill rooms where standard foam plugs lose seal.
Audit-Ready for TTB, FDA & OSHA
30+
year retention
One centralized digital record for every audiogram, fit test, and noise survey. 30+ year retention ready for any regulator or workers' comp claim.
Know Your Exposure
Typical Noise Levels in Distilleries
Bottling, milling, distilling, and barrel work all routinely exceed OSHA's 85 dBA action level — and many distilleries have never measured them.

Compliance Context
OSHA, TTB & FDA in Distilleries
Distilleries answer to multiple regulators on the same production floor — incomplete records create compounding audit risk.
OSHA 29 CFR 1910.95
Full HCP required: monitoring, audiometric testing, HPD, training, and recordkeeping for all workers above 85 dBA TWA. Penalties up to $165K per willful violation.
TTB & FDA Co-Inspection
TTB cellar audits and FDA FSMA inspections (flavored spirits, RTDs) often coincide with state safety reviews. Hearing conservation gaps surface across all three.
Workers' Comp Exposure
Hearing loss claims average $44K each in beverage manufacturing. One missed baseline can turn a stillhouse hire into long-term liability.
Workforce Exposure
Who Actually Needs to Be in the Program
Distilleries have multiple distinct high-noise zones — mill, stillhouse, bottling, cooperage. These are the roles that should be evaluated for HCP enrollment based on dosimetry and task variability — most cross the 85 dBA TWA action level, others sit close enough to require monitoring.
Rollout Plan
What a Soundtrace Rollout Looks Like
From first dosimetry walk to TTB- and FDA-ready records — designed around the production cadence of a distillery.
Initial Survey
Dosimetry across bottling, mill, stillhouse, mash, and warehouse. Identify all HCP-eligible roles.
Baseline Crews
Baseline production hires on day one. Catch-up baselines for veterans without recent audiograms on file.
Bottling-Aligned Testing
Annual audiograms scheduled around bottling runs. Fit testing in the mill room and on the bottling line.
TTB / FDA / OSHA Records
Centralized records ready for TTB cellar audits, FDA FSMA inspections, and OSHA visits — pulled from a single source of truth.
