Over 50 years ago, the founder of Marpac invented the original Sound ScreenŽ sound conditioner because he was having problems sleeping. It worked so well, he made it for his friends and family and ultimately the world. Today, the SoundScreen is still the most cost effective, best selling sound conditioner on the market. Marpac combines American ingenuity and craftsmanship to create a lightweight, yet durable appliance capable of many years of dependable 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 two-speed model provides even more control over the volume with a dual speed motor. 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 dual speed model 980a comes in a durable housing suitable for travel or use in the home or office.
