Artificial noise
From Wikipedia, the free encyclopedia
Artificial noise refers to waves, vibrations, audible sounds, electromagnetic signals, or other stimuli intentionally generated by human sources. Artificial noise is utilized in diverse contexts for different purposes. It plays a significant role in experimental research, urban environments, and sports, serving to either assess responses to controlled stimuli or enhance the atmosphere in various settings.
In experimental research
In experimental settings, artificial noise is a tool for examining how subjects respond to varying levels of stimuli. This involves manipulating the frequency or amplitude of noise to test, for instance, the efficacy of noise-reduction filters in microphones. Researchers generate specific noise patterns to determine if a device can effectively differentiate between noise and non-noise signals.
In urban environments
In cities, the term artificial noise often refers to sounds associated with human activity, such as traffic or light pollution. These noises are an unintended consequence of urban development and can affect the quality of life for residents.
