Examples
-
One possible explanation of this discrepant finding is related to the sensitivity of the speech measure and the procedure for measuring the S/N ratio.
Academic text (1993) -
An understanding of each is needed to design thin-film media for the desired signal-to-noise ratio, S/N, required by the magnetic recording system.
Academic text (1996) -
Signal detectability decreases as a function of increasing filter size (the filter passes more noise and decreases the S/N ratio).
Academic text (1992) -
A component high-frequency evaluation system was developed that provided the necessary outputs and high S/N ratios required for the study of high-frequency thresholds.
Academic text (1993) -
Half of the sentences were presented against a background of normal masking speech and half against a background of rotated masking speech (with a signal-to-noise S/N ratio of approximately +5).
Academic text (2012) -
The results revealed significantly higher S/N ratios in the unaided as compared with aided ears at the two highest presentation levels, consistent with the results of other investigations on auditory deprivation; reverse findings were obtained at the lowest presentation level.
Academic text (1993) -
For the SPIN materials, the up-down adaptive procedure (18, 19) was applied to the intensity of the 12-talker babble to derive the S/N ratio corresponding to 50 percent sentence recognition.
Academic text (1993) -
In audio engineering, achieving a higher S/N ratio is essential for clear sound quality.
-
During the experiment, they recorded the S/N ratio to ensure the signal was stronger than the background noise.

Etymology
S/N comes from the phrase signal-to-noise, where signal means 'useful information' and noise means 'unwanted background sound', so it shows how much the signal stands out from the noise. Think of someone speaking in a busy room: a high S/N means the voice 'stands out' clearly from the background, which is why engineers try to make it large.
