Sound Level Meter / Noise Level Meter
What is a Sound Level Meter / Noise Level Meter?
A sound level meter / noise level meter measures the intensity of sound in decibels (dB). It is a handy tool for assessing noise levels in various environments, from industrial settings to public spaces. It gauges how loud things are, helping to monitor and control sound for safety and comfort. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter, or noise dosimeter, a sound level meter uses a microphone to capture sound.
Sound level meter / noise level meter consists of a microphone, an amplifier, and a display unit. The microphone captures the sound, and the amplifier converts the electrical signal into a readable sound level value. Industries widely use sound level meters in various applications, including environmental monitoring, occupational safety, and noise control, to assess and manage sound levels in different settings.
