Ambient Noise


Definition - What does Ambient Noise mean?

Ambient noise is the cumulative exposure to noise factors inside the workplace with varying degrees of intensity, reflecting the type of industrial processes undertaken that often contribute to progressive hearing loss over time. The Occupational Safety and Health Administration (OSHA) establishes the parameters of noise decibel levels at a time-weighted average (TWA) value of 85 decibels (dB) inside an eight-hour work shift, indicating excessive noise dangers above the 85 baseline threshold.

WorkplaceTesting explains Ambient Noise

For many industries, the magnitude of ambient noise exposure can pose detrimental health effects for employees where long-term hearing loss often carries comorbid implications related to chronic stress, which can also interfere with productivity. An ergonomic workplace assessment serves as a criterion for identifying excessive noise hazards followed by administrative or engineering control solutions, respectively, by designating limited exposure during work shifts or introducing sound barrier partitions to mitigate ambient noise. Moreover, reduced hearing loss heightens the incidence rate for workplace accidents and injuries to occur due to an employee’s inability to hear warning installation units (i.e., emergency alarms) as a precaution against immediate hazards that require evacuation.

The Centers for Disease Control (CDC) underlines that ambient noise variables may hamper overall communication, often forcing employees to shout above the disparate noise ratio where audibility is significantly impaired. As a result, employers can draw on noise measurement devices such as noise dosimeters, sound level meters, or octave band analyzers to compute the difference and launch initiatives to address the problem. Because noise-induced hearing loss is an irreversible health condition, employers need to introduce hearing conservation programs that prioritize ambient noise deviations inside a workplace environment. A proactive approach through providing hearing protection devices and educational resources can mean the difference in tempering hearing deficits in employees throughout their careers.
