Why Occupational Noise Management Matters in Québec

Noise is a leading cause of occupational hearing loss. Excessive workplace noise leads to serious long-term consequences. Implementing effective noise controls enhances worker well-being, boosts productivity, and mitigates regulatory risk.

Permanent Hearing Impairment & Tinnitus

Irreversible damage caused by prolonged exposure to excessive noise levels in the workplace.

Elevated Accident Risks

Diminished concentration and communication barriers caused by constant noise exposure increase workplace incidents.

Chronic Health Issues

Ongoing noise stress contributes to fatigue, cardiovascular strain, and reduced cognitive performance.

Financial Liabilities

CNESST compensation claims and legal penalties resulting from inadequate noise management programs.

Our Hearing Conservation Services

A Data-Driven Approach

At Preventis, our occupational hygienists use a structured methodology to identify, analyze, and control noise exposure. We focus on eliminating or controlling noise at the source in line with Québec’s occupational hygiene best practices.

Sonometry (Workplace Noise Mapping)

Measures sound levels at workstations and across the facility.

Identifies fixed and mobile noise sources.

A visual noise map to highlight high-risk zones and prioritize actions.

Audiodosimetry (Worker-Specific Exposure)

Monitors individual occupational noise exposure over a full shift.

Calculates exact exposure metrics (Lex, LpAeq, dose) for each worker.

Supports targeted prevention plans for CNESST compliance.

Frequency & Octave Band Analysis

Analyzes noise by frequency to pinpoint source characteristics.

Uses 11 octave bands to guide engineering controls and hearing protection (PPE) selection.

Enables precise, customized intervention strategies.

Audiometry (Baseline & Ongoing Monitoring)

Establishes baseline hearing metrics for new hires.

Tracks long-term data to detect early hearing changes.

Integrates seamlessly with your broader hearing conservation program.

Real-World Applications

Manufacturing Plants

Map heavy machinery noise, monitor assembly line worker exposure, and implement targeted engineering controls.

Construction Sites

Conduct rapid noise assessments for temporary sites and align hearing protection with task-specific frequency data.

On-Site and Advisory Support

Field Assessments

In-person evaluations by certified technicians to identify dominant sources and viable controls.

Expert Guidance

Access to occupational hygienists for program design, device selection, and custom employee training.
