Is white noise harmful?

White noise can have both beneficial and potentially harmful effects depending on the context and age of the listener.

For Adults

• In adults, white noise can enhance brain states for learning and support cognitive functions like attention and memory. It operates by modulating activity in dopaminergic mid-brain regions, which influences learning and alertness. Low-intensity white noise is recommended, as it does not disrupt but rather supports these cognitive processes 1.

For Young Children

• For infants and young children, however, white noise can be detrimental, particularly if used consistently during developmental stages. Studies indicate that white noise can disrupt the auditory system, affecting the brain's ability to map sounds accurately, which could have long-term effects on auditory and language processing. It's suggested to use caution and possibly avoid prolonged exposure to white noise in young children's environments 2 3 4.

General Precautions

• When using white noise, it is crucial to maintain a moderate volume and not use it continuously over long periods, especially in environments with infants or young children 3.

In summary, the use of white noise is context-dependent, generally safe for adults as a background noise at low volumes, but should be used cautiously in settings with young children.
