4. Tuned mass damper - Wikipedia

   en.wikipedia.org/wiki/Tuned_mass_damper

   Now considering m 2 = ⁠ m 1 / 10 ⁠, the blue line shows the motion of the damping mass and the red line shows the motion of the primary mass. The amplitude plot shows that at low frequencies, the damping mass resonates much more than the primary mass. The phase plot shows that at low frequencies, the two masses are in phase.

5. Dumping (pricing policy) - Wikipedia

   en.wikipedia.org/wiki/Dumping_(pricing_policy)

6. Radiation-absorbent material - Wikipedia

   en.wikipedia.org/wiki/Radiation-absorbent_material

   For low-frequency damping in military applications, this distance is often 60 cm (24 in), while high-frequency panels are as short as 7.5 to 10 cm (3 to 4 in). An example of a high-frequency application would be the police radar (speed-measuring radar K and Ka band), the pyramids would have a dimension around 10 cm (4 in) long and a 5 cm × 5 ...
