What is Signal-to-Noise Ratio and How to Measure it
https://www.netspotapp.com/signal-to-noise-ratio.html
To get the signal to noise ratio, it’s the signal minus the noise, which means we have an average signal to noise of 40 in this case: Signal to Noise Ratio. How about room 2, where the signal is also -20, but the noise is -25. Now our signal to noise is much lower — around 5: Signal to Noise Ratio.

The NIST Speech SNR Measurement. In the service of the NIST mission to facilitate industrial advanced technology development, we focus on measurement science and standards development. Since the Smart Spaces of the future will require sensor based interfaces, particularly audio based for speech and speaker recognition, we have developed a signal-to …

Apply the A-weighting or CCIR-weighting (also called ITU-R 468 weighting), for example with endolith's code here. Subtract both numbers, this will be the final "Signal-to-noise ratio, A-weighted (re. 94 dB SPL) of the microphone".

The formula for Signal to Noise ratio= 10 log(signal/noise). If you solve for noise, it equals 10nv!
Signal-to-noise Ratio (SNR), Dynamic Range, and Noise ...
https://www.ap.com/technical-library/signal-to-noise-ratio-snr-dynamic-range-and-noise/
Noise in the presence of signal measurements are typically made by stimulating a device with a single or multi-tone signal and then analyzing the output of the device with a digital signal processing algorithm that produces a ratio of the energy in the noise of the output to the signal components of the output.

The APx500 Signal-to-Noise Ratio Measurement makes the two measurements and computes the ratio in one operation. Overview: Dynamic Range. Dynamic Range is an expression of the ratio of the largest signal a device can pass to the device’s noise floor. “Largest signal” usually refers to a signal at a specified degree of distortion, often 1%.

Signal to noise ratio. SNR (signal-to-noise ratio) is the comparison between the highest signal level emitted and the noise that comes out from the outlet of the equipment. This term represents the proportion between the strength of the unwanted noise and the audio signal emitted. The greater the distance between them, the better the signal to noise ratio is.

HOW WE MEASURE IT We fire a test signal known as a ‘log chirp’ (short, fast gliding sine wave burst) through the loudspeaker, as this gives strong low frequency excitation and good signal-to-noise ratio (unlike mls noise). Decay over 200mS (0.2sec) afterward is analysed, depicted as a waterfall plot and as a contour-coloured map.
