159 Hearing Protection: Basic
Skip to main content

Introduction

Noise, or unwanted sound, is one of the most common occupational hazards in American workplaces. The National Institute for Occupational Safety and Health (NIOSH) estimates that 30 million workers in the United States are exposed to hazardous noise. Exposure to high levels of noise may cause hearing loss, create physical and psychological stress, reduce productivity, interfere with communication, and contribute to accidents and injuries by making it difficult to hear warning signals.

This course will introduce you to the basics of sound and how exposure to excessive workplace noise can damage hearing. We'll also look at the Hierarchy of Controls for hearing protection, the various types of hearing protection available, and information on the Hearing Conservation Program and employee training.
