Noise is one of the most underestimated hazards in the workplace. Unlike a visible spill, a moving vehicle, or a machine guarding issue, hazardous noise happens quietly in the background, until it becomes a permanent problem.
Across Alberta, noise-induced hearing loss remains one of the most common, most preventable, and most expensive workplace injuries. And for companies operating in manufacturing, construction, hospitality, transportation, or any environment with equipment or crowds, understanding noise exposure isn’t optional, it’s a legal requirement.
That’s where a Noise Exposure Assessment becomes critical.
What Is a Noise Exposure Assessment?
A noise exposure assessment measures how much noise workers are exposed to during their shift, using professional tools like Sound Level Meters (SLMs) and dosimeters. These measurements provide employers with accurate data on:
-
How loud specific areas or tasks are
-
Whether workers’ daily exposure exceeds Alberta OHS limits
-
Which employees require audiometric testing
-
What hearing protection is necessary
-
Whether engineering or administrative controls are needed
The goal is to simply identify risk early so workers don’t suffer permanent hearing loss later.
Why Companies Can’t Rely on “It Doesn’t Seem Loud”
Noise hazards are deceptive. A work environment may feel manageable, but the cumulative effect — especially over an 8-hour shift — can quietly exceed safe limits.
Common signs noise levels might be too high:
-
Workers raising their voices to speak from arm’s length
-
Ringing in the ears after shifts
-
Employees reporting fatigue or difficulty hearing conversations
-
Loud equipment operating for long durations
-
Inconsistent use of hearing protection
The only way to know for sure is through formal, measured testing.
Alberta OHS Requirements Employers Must Know
Under Alberta OHS legislation:
-
Workers exposed to 82 dBA or higher over an 8-hour shift must receive audiometric testing
-
Employers must identify, measure, and control hazardous noise
-
Noise hazard areas must be posted with signage
-
Hearing protection must meet CSA standards
-
Employers must maintain a Hearing Conservation Program if limits are exceeded
Failing to follow these standards can lead to fines, claims, and permanent hearing injuries.

The Hidden Costs of Ignoring Noise Risk
Hearing loss doesn’t happen all at once — it’s gradual, irreversible, and completely preventable with the right systems in place.
Companies that skip proper assessment often face:
-
Increased WCB claims
-
Worker fatigue, stress, and communication issues
-
Lower productivity and higher turnover
-
Liability risks during audits or incidents
-
Long-term damage to employee health
A short assessment can prevent years of complications.
