Brown noise is a noise which contains all the frequencies that are audible to humans, boosting the lower frequency range. It is very good for blocking out annoying noises, thereby allowing better concentration for studying, reading, working and sleeping. It is also good for calming babies and allowing them to sleep. Additionally, there are many claims that it is useful for treating conditions such as tinnitus and hyperacusis (or hyperacousis), a debilitating hearing disorder.
