What is a spectrum analyzer

A spectrum analyzer is a device or software tool that measures and displays the magnitude of an input signal versus frequency across the spectrum of frequencies.

What is a decibel meter

A decibel meter (or sound level meter) is an instrument used to measure sound pressure level (SPL) and quantify noise or sound intensity in decibels.
