Sound Level Meters
A sound level meter (SLM) is an electronic instrument designed to measure sound pressure levels in the air, typically expressed in decibels (dB). It uses a microphone to capture sound, an electronic circuit to process the signal, and a display to show the measured level.
Real-time Applications
