Elevated workplace or environmental noise can cause hearing impairment, tinnitus, hypertension, ischemic heart disease, annoyance, and sleep disturbance. [ 3][ 4] Changes in the immune system and birth defects have been also attributed to noise exposure. [ 5] Although age-related health effects ( presbycusis) occur naturally with age, [ 6] in ...
Noise-cancelling headphones often combine sound isolation with ANC to maximize the sound reduction across the frequency spectrum.

In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. [ 1] The term is used with this or similar meanings in many scientific and technical disciplines, including physics, acoustical ...
