Over 50 years ago, the founder of Marpac developed the original Sleepmate® sound conditioner because he was having trouble sleeping. It worked so well, he made it available to his friends and family and ultimately the world. Today, the Sleepmate® is still the most economical, most popular sound conditioner on the market. Marpac combines American ingenuity and craftsmanship to create a lightweight, yet durable appliance capable of many years of reliable service. These sound conditioners create a consistent, smooth sound of rushing air commonly called white noise. The tone and volume of the sound are controlled by simply rotating the "cap" and "collar" of the housing. This "white noise" sound effectively masks unwanted noises and creates a sense of calm, making it easier to concentrate, relax and/or sleep. These sound conditioners are recommended for restless sleepers, shift workers, infants, children, students, apartment dwellers, office workers (for confidentiality) and many others. The single speed model 580 comes in a durable plastic housing suitable for travel or use in the home or office.
