Background white noise played at low volume can support learning by increasing alertness and dopamine activation.

“The idea is that it's playing at a low enough volume that you forget it in the background and that it's supporting learning by bringing your brain into a heightened state of alertness and especially this heightened state of dopamine-- dopaminergic activation of the brain, which will make it easier to learn faster and easier to learn the information.”

“white noise, provided that white noise is of low enough intensity, meaning not super loud, it actually could enhance learning to a significant degree.”

“it appears that white noise itself can raise what we call the basal, the baseline levels of dopamine that are being released from this area, the substantia nigra.”

“it does appear that turning on white noise at a low level, but not too loud, can allow you to learn better because of the ways that it's modulating your brain chemistry.”
