A sound level meter is a device used to measure the intensity of sound in decibels (dB). It captures sound waves through a microphone and displays the sound level on a digital or analog scale. These meters are commonly used in various settings, including construction sites, concerts, and environmental monitoring, to ensure noise levels are within acceptable limits. Sound level meters can vary in complexity, from simple handheld models to advanced devices with data logging capabilities. They are essential tools for audiologists, engineers, and environmental scientists who need to assess noise pollution and its impact on health and well-being.
