When a pianist actually looks at the damper action while pedaling, or watches the hammers strike the string for only a split second, her body will shift to a more kinesthetic, intuitive and efficient mode. During performance, most students will need to stand while depressing the damper pedal to access the interior of the piano. While not the best way to introduce damper pedaling techniques, four-voiced chorales are highly appropriate for reinforcing or testing established pedaling techniques. The basic notes of Philip Glass's music are very few and usually surrounded by a haze of the overtones created by the damper pedal of the piano.

The tank has been equipped with torsion bar running gear and hydraulic dampers have been fitted to the first and last pair of wheels. Its twin-turbo engine has 425 bhp instead of 340 bhp but the most significant work has been saved for the chassis, which gains stiffer springs, race-specification dampers and a front anti-roll bar. Thankfully, the dampers and shock absorbers do their job without being easily visible, taking away nothing from Foster's ‘blade of light.’ Also known as crankshaft dampers, these devices dwell in the harsh environment of a vehicle's engine and serve to reduce the noise and vibration of a vehicle. The dampers react in real time to variations in the road surface or driving style and adjust themselves automatically to the prevailing conditions. The keen driver is more likely to appreciate the difference made by lowering the car, fitting 19 in wheels with special Pirelli tyres, and the Sky Hook active dampers that act 10 times faster than conventional adaptive damper systems.

Each damper then effectively does its own thing, responding to what each individual wheel is doing and controlling the stance, roll and pitch of the car. MacPherson's design placed the damper inside the spring and did away with the upper arm, thus halving the number of components. The suspension is custom made double wishbones with coil-over dampers front and rear, and while the rear also utilises custom made fabricated steel uprights, the front end gets surprisingly mundane by using uprights from an old Cortina.

Closing outside air dampers or shutting off exhaust fans - either partially or completely - reduces heating and cooling loads caused by the intake of outside air. Cycling fans and adjusting damper settings can cut fan motor loads and reduce exfiltration, potentially cutting uncontrolled exhaust of conditioned air. Check the seal on the flue damper and make it as snug as possible. They also should have electrically operated dampers to limit and control the amount of outside air entering the return side of the air handler. Service openings must be provided in air ducts adjacent to each fire damper, smoke damper and smoke detector to accommodate inspection and operational tests. For example, on most bath fans and kitchen exhaust hoods, the damper is located on the housing of the fan unit, right at the point where the vent pipe attaches to the housing.

When you use your fireplace, you can reduce the stress on your heating system by opening dampers at the bottom of the firebox. An open damper in a 48-inch square fireplace can allow a heat loss of up to 8 percent through the chimney. According to the latest standards, dampers must either be removed or permanently secured in the open position if gas logs are installed. When your home is warm enough, the thermostat causes the damper to close, and the fire burns at a reduced level. When the fireplace is not in use, keep the flue damper tightly closed. These pressure transducers are connected with the dampers via a control unit which changes the position of the dampers in accordance with the airflow condition. Airflow into the base of the flue and out of the top is regulated by dampers controlled by the building management system, which also controls airflow from the building into the flue. Similarly, closing outdoor air dampers will reduce humidity levels but will also reduce the amount of outdoor air being brought into the building, potentially causing indoor air quality problems. 2Australian NZ An unleavened loaf or cake of flour and water baked in wood ashes. 〈主澳/新〉硬面包，硬烧饼 Example sentencesExamples As representative of everyday staple I would like to single out damper, a simple flat bread made of self-raising flour and hot water and baked on the hot ashes or on a wire over a small fire.
