signal-to-noise ratio
Useful versus interference
Signal-to-noise ratio measures how much useful information exists relative to irrelevant or distracting interference.
In electronics and audio engineering, it quantifies the strength of a desired signal compared to background noise—higher ratios mean cleaner sound or clearer transmission.
The term has spread into everyday use to describe any situation where meaningful content competes with clutter: The signal-to-noise ratio in my inbox is terrible lately.
Online discussions with too much bickering and too little substance are said to have a low signal-to-noise ratio.
