Resonance |
The condition in which an object or system is subject to an oscillating force having a frequency close to its own natural frequency resulting in amplification of the signal. |
|
|
Natural frequency: definition and determinants. |
The frequency of of oscillation that an object or system will adopt freely when set in motion or supplied with energy. Decreases with increased length, decreased width, decreased elasticity (material and contents, e.g. air bubbles). |
|
|
Damping |
A decrease in the amplitude of an oscillation as a result of energy loss from a system owing to frictional or other resistive forces |
|
|
Frequency response |
Relationship between the frequency of the measured waves and the amount of amplitude amplification which might occur as the result of resonance |
