The Marpac 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.

These Sound Conditioners are recommended for restless sleepers, shift workers, infants, children, students, apartment dwellers, office workers (for confidentiality) and many others.
