About Sound Levels
Measured in decibels (dB), volume ratings indicate how much noise equipment makes. Some common volume levels include a whisper @ 20 dB, a refrigerator @ 40 dB, a conversation @ 60 dB, and a light machine shop @ 90 dB. OSHA recommends hearing protection for exposure to 80 dB and greater.
Heater and Air Conditioner Duct Booster Fans

Insert these fans directly into your ductwork. They give small heaters and air conditioners a boost to circulate air through ductwork. The crimped end construction makes inserting the fans easy.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
