WebSignal to noise ratio can be defined as the ratio of the level of the desired signal to the level of the background noise. It is given by SNR or S/N. SNR is expressed in Decibels (dB). … WebA high SNR (signal-to-noise ratio) is generally better than a low SNR. SNR is a measure of the strength of the audio signal relative to the level of background noise. A high SNR means the signal is stronger than the noise, resulting in a cleaner and clearer audio signal.
