White Noise

Definition

White noise is a consistent sound that contains equal intensity across all frequencies within the human hearing range, often described as a hissing or static-like noise. This uniform distribution of sound energy allows white noise to mask other sounds, making it particularly effective in noise control and audio applications. Its relevance extends to human perception, as it can influence sleep patterns, concentration levels, and the ability to filter out distractions in noisy environments.
