Noise
Noise is any unwanted or unpleasant sound that disrupts peace or communication, often characterized by its randomness and lack of meaningful pattern. In modern contexts, it extends to non-auditory fields like electronics, where it refers to random fluctuations that interfere with signals, or in data analysis, where it muddles useful information—making it a key concept in filtering out distractions for clearer insights.
Did you know?
In 1955, engineers at Bell Labs discovered Johnson-Nyquist noise, a fundamental thermal agitation in electronic circuits that sets the limit for the quietest possible signal, affecting everything from your smartphone to space telescopes—and it's impossible to eliminate entirely, no matter how advanced the technology.
