Sound Level Meter: Measure Sound Pressure Levels

A sound level meter is a device used to measure sound pressure levels. It is commonly used in noise pollution studies to determine safe noise exposure levels.

What is Sound Level Meter?

A sound level meter, also called a decibel meter, is an instrument used to measure sound pressure levels and noise exposure. It is used by acousticians, health and safety professionals, researchers, and others who need to quantify and analyze sound in various environments.

A basic sound level meter consists of a microphone, processing circuitry, and a digital display that shows the sound pressure level in decibels (dB). More advanced models may include data logging capabilities to record sound over time, audio recording functions, and octave or third octave band filters that allow frequency analysis of sound.

Common applications of sound level meters include:

• Occupational noise surveys - to determine if noise levels in workspaces are within safe limits
• Environmental noise monitoring - measuring noise from transportation sources, construction sites, etc
• Product testing - analyzing noise emissions from machinery, appliances, etc
• Acoustical testing of rooms and auditoriums
• Research - quantifying noise exposure for health studies, analyzing wildlife response to noise, etc

Using a sound level meter allows accurate measurement of noise levels to help determine appropriate noise controls, advise personnel on allowable exposure times, demonstrate legal compliance, troubleshoot noise issues, and more. They are an essential tool for controlling noise hazards.
