What is Signal to Noise Ratio? - Understanding Signal to Noise Ratio Specifications - Stereo Specifications. Question: What is Signal to Noise Ratio?
Answer: Signal to noise ratio is a specification that measures the level of the audio signal compared to the level of noise present in the signal. Signal to noise ratio specifications are common in many components, including amplifiers, phonograph players, CD/DVD players, tape decks and others. Noise is described as hiss, as in tape deck, or simply general electronic background noise found in all components.
How is it Expressed? As the name suggests, signal to noise ratio is a comparison or ratio of the amount of signal to the amount of noise and is expressed in decibels. Why is it Important? Unfortunately, all components add some level of noise to an audio signal but it should be kept as low as possible.
