Acoustic tile: Any of a variety of ceiling tiles designed for an optimum sound muffling effect. Usually made of gypsum and/or paper fiber, with numerous small holes or bumps to break up sound waves.

Ducting: Lightweight tubing designed to provide fresh air or expel not-so-fresh air. Usually made of galvanized metal or plastic.

Soundproofing: Complete elimination of sound emanation from a room. Extremely expensive, and usually cost-effective only for recording studios or other specialized spaces. In most homes, noise abatement is the true practical goal.

2torial #0435: Learn2 Block Out Sounds in a Room (Continued) Insulate for acoustic isolation Metal ducting for the heating and air conditioning system will carry all kinds of noise through the house. Insulating the ducting with sheets of heat-safe materials will cut way down on the "echo chamber" effect. Bare floors and stairs transmit much more noise and vibration then carpeted areas. Wall-to-wall (preferably with floor padding) is the better insulator, but area rugs are better than nothing. Acoustic ceiling tile is very effective, both at reducing the overall noise level of a room and in reducing noise from the room above. If you're in a college dorm (or want to feel like you are) thumbtack a tapestry up on the ceiling to cut down on the industrial feel. Outside noise can be reduced by replacing blinds with heavy drapes or curtains. Lined curtains are even better.   Step 2
