The Marpac Sound Screen 980 is a dual speed sound contitioner.
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. 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.
