damping material การใช้

• Other damping materials include products that use wood, titanium or synthetics.
• It has also been used as a sonic damping material in sensitive phonograph components.
• This is often due to the degradation of the damping materials in the component.
• Sound is also dissipated into the fiberglass damping material.
• The cabinet is filled with acoustic damping material.
• :Obviously if energy is being dissipated in a material, that material is called a damper or damping material.
• But the energy needs to be absorbed somehow so, could I just use damping material to damp all resonances?
• This model had carbon fiber fenders and clutch cover, sound damping material, adjustable Showa suspension, and an aluminum swingarm.
• The Wescam ball is attached to a helicopter or airplane through a shock absorber that uses springs and other damping materials.
• They generally achieve this by incorporating a tiny diaphragm to reduce low frequencies, together with absorbent or damping material for high frequencies.
• The constrained layer damping tools usually apply high damping material in the tool end's clamping interface, at specific areas where vibration strain energy concentrates.
• The engineer might focus on changing materials, using a damping material, isolating the machine, running the machine in a vacuum, or running the machine slower.
• Most stainless steel sinks are made by noisier than most other sink materials, although better sinks apply a heavy coating of vibration-damping material to the underside of the sink.
• In some loudspeaker designs, a hole is cut at the center of the parabolic dish, or damping material placed, such that no sound is reflected directly at the speaker driver.
• A reason for this may be that adding damping material is a needlessly inefficient method of increasing damping; the same alignment can be achieved by simply choosing a loudspeaker driver with the appropriate parameters and precisely tuning the enclosure and port for the desired response.
• This speaker introduced the concept of flat crossover, and at the same time used some innovative solutions as the upward inclination of the baffle, obtained with the special stands and the use of damping material ( foam ) in the baffle, in order to reduce the diffraction phenomena.
• Wind, powertrain, road and vehicle body noise was reduced by improving interior acoustics through new damping materials, a total of 10 shear-style isolating body mounts, heavier sealing of body and panels, redesigned rubber door seals, and extensive use of interior structural acoustic foam in the upper B-pillars, upper and lower D-pillars and floor pan.
• Damping materials like Akasa's PAX . mate or Dynamic Control's Dynamat can do the same for the PC case's walls . ( These products, from $ 20 to $ 40, are available from computer dealers and Web sites catering to do-it-yourselfers, as are other items mentioned here; a resource list is at nytimes . com / circuits .)
