The SNR (Signal-To-Noise Ratio) of a system or component is defined as the ratio of signal level to the noise level. SNR is expressed in decibels. It is calculated by dividing the signal power by the noise power. A ratio bigger than 1 dB indicates that the signal is more than the noise.

In basic terms, SNR is the difference between the desired signal and the noise floor. Also, in terms of definition, the noise floor is the specious background transmissions that are produced by other devices or by devices that are unintentionally generating interference on a similar frequency.

Signal-to-noise ratio (SNR) is the measurement used to describe how much desired sound is present in an audio recording, as opposed to unwanted sound (noise).
Signal-to-noise Ratio Definition - DeepAI
https://deepai.org/machine-learning-glossary-and-terms/signal-to-noise-ratio
The SNR defines the ratio of the power of a signal to the present background noise. In order for the SNR to accurately describe the data, both the power of the signal and the background noise must be measure at the same or equivalent points in a system of reference.
What is SNR and How Does it Affect Your Signal?
https://www.wilsonamplifiers.com/blog/what-is-snr-and-how-does-it-affect-your-signal/
SNR is short for “Signal to Noise Ratio,” and can also be expressed as S/N ratio. It is the ratio of signal power to that of all other electrical signals in the area, known as the noise level. Noise is measured by the Root-Mean-Square (RMS) value of the fluctuations over time. This ratio is expressed in decibels (dB).

SNR essentially characterizes the ratio between the full scale output of a device and its idle noise. Dynamic range characterizes the ratio between the full scale output of a device and the spurious noise products created when a device is producing a very low level signal.

SNR is a ratio of two measurements, level and noise measurements, expressed in dB. Signal level, measurement bandwidth, and weighting filter must be defined. Dynamic range is like SNR but noise is measured in the presence of small signal; results should be the same.

https://dsp.stackexchange.com/questions/35041/snr-estimation-in-segmented-speech-signals
SNR = 10 log 10 ( P ( x) − P ( n) P ( n)) Where P ( x) and P ( n) are the power of the contamined signal 'x' and the noise signal 'n' ('n' is basically a copy of 'x' but with zero energy in the speech segments). The mean was subtracted from both signals as requested in the paper.
