Over 40 years ago, our founder 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 the Marsona SleepMate, a lightweight, yet durable appliance capable of many years of reliable service. The Marsona SleepMate sound conditioners create a consistent, smooth sound of rushing air. 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.

The Marsona SleepMate and Sound Screen sound conditioners are recommended for restless sleepers, shift workers, infants, children, students, apartment dwellers, office workers (for confidentiality) and many others. We offer the single speed Marsona SleepMate 580 or the dual speed Marsona SleepMate 980, both in a durable plastic housing suitable for travel or use in the home or office. Both models are available in either Marsona Sound Screen or Marsona SleepMate name.
