Understanding the Science Behind White Noise and Frequency Perception

Jan 23, 2024

White noise is a type of sound signal that people perceive when multiple frequencies are presented simultaneously across the audible frequency range. This sound has equal intensity at each frequency, creating a smooth, consistent sound profile experienced as a uniform audio backdrop. Our ability to perceive white noise is based on the working of our auditory system, which allows us to distinguish and process different sounds. With understanding of the frequency ranges involved in producing white noise and how these relate to sound perception, we can better appreciate the various applications for white noise, such as sleep assistance, tinnitus relief, and sound masking.
