What is a Sound Level Meter? Sound level meters are instruments designed to respond to noise much like the human ear. The measurements taken by sound level meters are compared to known standards to determine if the noise level could have a detrimental effect on human hearing. Types of Sound Level Meters Type 3Â â€”Â Low cost models for basic sound checks.Type 2Â â€”Â Models that meet OSHA and other ordinance testing requirements.Type 1Â â€”Â Precision for lab testing (Extech doesn't have one).DosimetersÂ â€”Â Measure work noise exposure according to OSHA.AnalyzerÂ â€”Â analyzes noise in narrow bands.

Hearing loss from loud sound affects millions of people. Noise-induced hearing loss is preventable, but most people don't know how long they can listen to loud sound without risking hearing damage. A single noise exposure may not result in hearing loss, but permanent damage to the inner ear from noise adds up over time. The accumulation of too much noise day by day, year after year, is the determining factor in hearing loss risk.
