In terms of insulation, noise reduction refers to suppressing unwanted sounds in various areas of the home. It's an added bonus that a well-insulated house will have, and this is a fact that most homeowners don't consider during construction. Home theaters, media rooms and playrooms are noise-laden environments that can adversely affect sleep, stress levels and quality of life. Choosing the right insulation can help reduce room to room noise levels and ensure that your home is a haven of peace and quiet. It can also reduce airborne sound, ambient sound, that originates from the external environment, particularly for homeowners who live near a busy street, an airport, or in a multi-unit dwelling.

Thermal insulation materials -- fiberglass, cellulose, spray foam, cotton batts, or rigid boards -- are all that's needed to create a quieter environment.
