Episode 140 focuses on understanding noise as a hazard, why it’s frequently overlooked, and how leaders should properly identify and assess noise risks in the workplace. Dr. Ayers emphasizes that noise is not just an annoyance—it is a physical hazard that causes permanent hearing loss, communication failures, and increased risk of injury.
This episode reinforces that hazard identification must include sensory hazards, not just visible ones.
Noise is a serious, irreversible hazard that must be identified through measurement, not assumptions. If leaders rely on “it doesn’t seem loud,” workers end up unprotected.
Dr. Ayers explains that noise hazards are frequently missed because:
People get used to loud environments
Supervisors rely on subjective judgment
Noise doesn’t cause immediate pain
Workers don’t complain until damage is done
This leads to chronic underestimation of risk.
The episode stresses that:
Noise‑induced hearing loss cannot be reversed
Damage accumulates gradually
Workers often don’t notice until it’s too late
Even moderate noise can cause long‑term harm
This makes early identification essential.
Dr. Ayers highlights additional risks:
Communication breakdowns
Missed alarms or warnings
Increased fatigue
Higher incident rates due to distraction
Stress and reduced concentration
Noise is a system‑level hazard, not just a health issue.
The episode emphasizes that leaders must:
Use sound level meters or dosimeters
Compare readings to regulatory limits
Consider duration as well as intensity
Evaluate peak noise and impulse noise
Assumptions are not acceptable—noise must be measured.
Dr. Ayers reinforces the hierarchy of controls:
Engineering controls (enclosures, dampening, isolation)
Administrative controls (rotation, scheduling)
Hearing protection (last line of defense)
PPE alone is not a noise‑control strategy.
Noise is a real, measurable hazard that requires deliberate identification and control. Leaders must stop relying on subjective impressions and start using proper measurement tools to protect workers from irreversible harm.
