Description
The world is a noisy place: cars, power tools, crowds, machinery, and other common sources produce amounts of noise that can, with continued exposure, lead to permanent hearing loss. Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one?
