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.

Bottling Line Operator92–105 dBA
Bottling lineVery HighHighest sustained exposure in the distillery; daily HPD verification recommended.
Stillhouse Operator85–95 dBA

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.

Phase 1Site Walk

Initial Survey

Dosimetry across bottling, mill, stillhouse, mash, and warehouse. Identify all HCP-eligible roles.

Phase 2Production Cycle

Baseline Crews

Baseline production hires on day one. Catch-up baselines for veterans without recent audiograms on file.

Phase 3Annual Cycle

Bottling-Aligned Testing

Annual audiograms scheduled around bottling runs. Fit testing in the mill room and on the bottling line.

Phase 4Audit-Ready

TTB / FDA / OSHA Records

Centralized records ready for TTB cellar audits, FDA FSMA inspections, and OSHA visits — pulled from a single source of truth.

Distillery FAQ

Common Questions From Liquor & Spirits Operators

Why is hearing conservation a craft distillery problem?
Craft distilleries scaled bottling and mill operations faster than they scaled EHS. A 92+ dBA bottling line is the same legal exposure whether it sits inside a 12-person craft house or a 500-employee producer.
Are RTD (ready-to-drink) and flavored-spirits lines under FDA FSMA?
It depends on the product and process. Many RTD and flavored spirits formulations carry FDA jurisdiction layered on top of TTB, particularly when non-alcoholic ingredients dominate the formulation or when the SKU is classified outside of TTB's traditional spirits scope. Soundtrace exports are designed to support overlapping FDA, TTB, and OSHA documentation when FSMA does apply — confirm jurisdiction with your regulatory counsel.
Can ear plugs maintain seal in dusty mill rooms?
Standard foam plugs often lose seal in grain dust. Fit testing with the actual plug used in the mill room measures real-world attenuation and catches the problem before it shows up in an audiogram.
Does age correction apply to my older stillhouse operators?
Age correction (OSHA Appendix F) is optional for general industry but commonly applied. We apply it consistently and document the methodology so STS determinations hold up to audit.
How do you test contractor labor and packaging crews?
Contracted bottling, packaging, and warehouse crews are tracked under their own enrollment but share your Soundtrace platform. The host distillery typically coordinates baselines on day one of contract assignment.
What does the audit-ready TTB / FDA / OSHA workflow look like?
Each regulator gets a different export view from the same source data: OSHA-formatted CFR 1910.95 logs, TTB-style cellar safety attestations, and FDA FSMA-compatible production-floor safety records.

Your Bottling Line Doesn’t Stop.
Your Compliance Program Shouldn’t Either.
