What types of noise would a worker typically encounter?

A worker would typically encounter continuous, intermittent, and impulse/impact noise types because these classifications help in understanding and quantifying various noise exposures in work environments.

Continuous noise refers to sounds that are persistent over time, such as machinery operating consistently during a work shift. This type of noise poses a risk for hearing damage if exposure is prolonged without adequate hearing protection.

Intermittent noise consists of sounds that occur at irregular intervals, which can vary in duration and intensity. Examples include alarms, announcements, or machines that operate sporadically. The unpredictability of this type of noise can also contribute to the potential for hearing loss if workers are frequently exposed.

Impulse/impact noise includes sudden bursts of sound that can significantly raise noise levels in a matter of milliseconds. Examples include gunfire, explosions, or the clashing of metal. Such noise can be particularly damaging to hearing as it can cause immediate and irreversible damage, even at lower volumes, due to its sudden nature.

While other options include valid terms, they do not accurately encompass the comprehensive spectrum of noise types that a worker might typically encounter in various industries, which includes the expressive and diverse nature of impulse and impact noises.
