How it works?

• Relaxes and reduces stress
• Increases focus while enhancing privacy
• Helps you sleep by blocking distractions
• Soothes headaches and migraines
• Masks tinnitus (ringing of the ears)
• Pacifies crying babies

Explanation?

Sound masking can be explained by analogy with light. Imagine a dark room where someone is turning a flash light on and off. The light is very obvious and distracting. Now imagine that the room lights are turned on. The flash light is still being turned on and off, but is no longer noticeable because it has been "masked". Sound masking is a similar process of covering a distracting sound with a more soothing or less intrusive sound.

The masking must reduce the difference between the steady background level and the transient levels associated with both speech and other sounds. Motivation and productivity are improved when this is accomplished. The masking sound itself must not change rapidly and should be as meaningless as possible.

Sound masking reduces or eliminates awareness of pre-existing sounds in a given area and can make a work environment more comfortable, while creating speech privacy so workers can better concentrate and be more productive. Sound masking can also be used in the outdoors to restore a more natural ambient environment.

White noise is a common synthetic noise source used for sound masking by a tinnitus masker.
