damper

DAM-per. [English] 1. In a piano, dampers are movable mechanisms covered with felt that rests on the strings to prevent unwanted vibration of the strings. When the damper pedal is pressed, the dampers rise up off the strings, and a more resonant, sustained sound is achieved.

: to make (something) less strong, active, or exciting. His bad mood put a damper on the celebration. He was putting a bit of a damper on her spirits.

More physical kinds of dampers include a device that restrains air in a chimney, by blocking or directing its flow, and a pad that's made to soften or muffle the sound from a musical instrument.

Dampers are a lot more than simple airflow adjusters. They are integral to the control of cool, warm, high temperature, dirty, or even toxic air. They may also be used for fire protection. Dampers maintain air quality and provide worker safety, which is why they are essential for industrial airflow regulation.

A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses.

A damper is, at its most high level, just a Newtonian fluid: it resists motion. The force that it imparts on the body is stronger when it is moving faster.

Vibration damping is a term that's used in industrial, electronic and ergonomic applications when there is a need to reduce the amount of energy that's produced by the system. Normally engineers try to address and reduce this energy at its source so the disturbing force is not at or near a natural frequency.

pianos …found on most pianos, the damper pedal on the right lifts all the felt dampers above the strings, allowing them all to vibrate freely; the left pedal shifts the keyboard and action sideways to enable the hammer to strike only one of the two or three unison strings of each…

Vibration damping dissipates vibration energy. It absorbs or changes vibration energy, reducing the amount of energy transmitted through the equipment or structure. Understanding these processes - and when to use them - also requires understanding two concepts: transmissibility and natural frequency.

With passenger comfort its primary function, the Yaw Damper is an independent subsystem compatible with any autopilot system. It enhances directional stability by eliminating short-term yaw oscillations.

Damping is one of the most effective methods of controlling noise and vibration. It is a process that converts vibrational energy into heat, eliminating the vibrational energy through friction and other processes.

A damper is a device. Damping is the effect of the device. A dashpot is the name of a certain type of mechanical damper that has a piston in a cylinder and a hole (or many holes) in the cylinder to let fluid go in and out of the cylinder as the piston moves back and forth. That causes the damping effect.
