Naturally Produces White Noise The Dohm produces white noise naturally, without digital loops or recordings. Its consistent, unobtrusive sound blocks out everyday noises, like neighbors' music, a partner's snoring, or coworkers' chatter. The white noise produced by the Dohm can also be used as a shield to provide confidentiality for doctor's appointments, phone calls with clients, or to otherwise protect personal privacy. For those who prefer some noise to no noise at all, the Dohm provides a soft, comfortable background sound where it might otherwise be too quiet. For Home, Office, or Travel Use While it is most commonly used in the bedroom to improve quality of sleep, the Dohm is also useful in many other situations. Use it in a home nursery or day care center to help soothe babies to sleep, in a college dorm room to keep students focused on schoolwork, in a busy office with little separation between cubicles, or in any environment where unwanted or intrusive noise is a problem. You can also use this sound conditioner when you are traveling to make your hotel room feel more like home. Set Speed for Ideal Volume and Tone This sound conditioner offers two-speed operation, which means you can choose the volume and tone that is best for you. First choose "high" or "low" setting, then fine-tune the sound by twisting the cap and collar.
