Definition

Noise refers to unwanted or random sound, typically characterized by its disruptive, irregular, or chaotic nature. It consists of various frequencies and amplitudes, often perceived as a disturbance or interference in the background that can mask or obscure desired sounds. Noise can originate from multiple sources, including machinery, traffic, electrical interference, or environmental factors, and it may be undesirable in certain contexts, such as in communication, work, or living environments. Reducing or eliminating noise is a common goal in engineering, urban planning, and workplace design to improve overall comfort, safety, and communication.
