Sound Level Test System

Why Are Sound Level Measurements So Important?

Whether manufacturing vehicles, mining natural resources or operating machinery on a construction site, a single common factor can bring your operation and productivity to an absolute halt. That factor is noise. According to the Centers for Disease Control, hearing loss can result from a single loud sound (like firecrackers) near your ear. Or, more often, hearing loss can result over time from damage caused by repeated exposures to loud sounds. The louder the sound, the shorter the amount of time it takes for hearing loss to occur. Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. The CDC advises that noise above 70 dB over a prolonged period of time may start to damage your hearing, and loud noise above 120 dB can cause immediate harm to your ears.
