Introduction

Dosimetry

Measuring noise in the workplace is an important element of hearing conservation programs and noise reduction programs. With a noise dosimeter, you can assess and determine a worker’s daily exposure to noise levels. This information can be used to ensure compliance with regulatory bodies or to ensure if hearing conservation programs are needed.

To get you started quickly with the Edge, the first chapter is dedicated to introducing basic noise dosimetry terms and information. The subsequent chapters will guide you through setting up the dosimeter, running studies, and assessing your results with easy to follow steps and illustrations.
