Adheres or is sprayed onto relatively thin metal panels so as to extract energy when panels flex Lowers "Q" of each panel mode Goal: to reduce air low (over the panel)-induced vibration and radiated noise
Damper - A part of an air conditioning system that can be opened or closed to allow more or less air to pass
{i} person or thing which causes gloom or depression; device that regulates the draft in a stove or fireplace; device which reduces the intensity of sound in a musical instrument
An adjustable gate installed in a duct for the purpose of regulating airflow or introducing outside air to the ducting system
a device that decreases the amplitude of electronic, mechanical, acoustical, or aerodynamic oscillations a movable iron plate that regulates the draft in a stove or chimney or furnace
That which damps or checks; as: (a) A valve or movable plate in the flue or other part of a stove, furnace, etc
A movable plate in a fireplace that allows smoke and fumes to travel up the chimney's flue
The mechanically adjusted mechanism located at the discharge end of a ventilating system located in the ceiling or floor The damper adjustor will regulate the volume of air being discharged
The mechanical device that regulates the flow of air up a chimney or in an air vent
To put a damper on something means to have an effect on it which stops it being as enjoyable or as successful as it should be. The cold weather put a damper on our plans
Found in ductwork, this moveable plate opens and closes to control airflow It is also used in zoning to regulate airflow to certain rooms
A device that is located in ductwork to adjust air flow There are basically two types of dampers: manual and motorized A manual damper generally consists of a sheet metal (or similar material) flap, shaped to fit the inside of a round or rectangular duct By rotating a handle located outside of the duct, a technician can adjust air flow to match the needs of a particular area or room (see Balancing) A motorized damper is generally used in a zoned system to automatically deliver conditioned air to specific rooms or zones (see Zone Control)
