Sleep Therapy includes helping to wash out the lower levels of noise for better sleep. These recordings were produced because the producer that created this actually sleeps every night to real air fans in the room. These create a soundbed that lowers the chance of waking up due to outside sources, or sharing a bed, or noisy pets. Sometimes there are airports, traffic and humming in the air that these 1-hour long original ACTUAL FAN RECORDINGS will sonically absorb. They can mimic in situations where you may not have a fan, or do not want to have a fan moving air around while you sleep.
These are all smooth toned throughout, and do not change within their respective recordings. No warbles, no wobbles, no squeaks - these are clean droning fan sounds for your next flight where you don't want music but you need a white noise wash to stay zoned out. This is Doctor Level treatment from our labs to your lobes.
