What is considered excessive noise?
The amount of on-the-job noise exposure can be determined through various testing devices.
Excessive noise is defined as 85-90 decibels or more over an 8 hour period.
Examples of noise levels considered dangerous by experts are a lawnmower, a rock concert, firearms, firecrackers,
headset listening systems, motorcycles, tractors, power tools and industrial machinery.
