Resonance can be engineered to strengthen sound or damped to prevent malfunction

Evidence

Resonance is a phenomenon found frequently in physical systems. It may be desired, undesirable, or even harmful, depending on the case. If the radiation of sound of a musical instrument is too weak, then building a body or sound board with stronger resonances may help to increase the loudness of the sound source. At the same time, the resonance colours the sound which, if properly designed, can make it more appealing. On the other hand, resonances may amplify noise or even cause a machine to malfunction due to strong resonant behaviour. In such a case, damping helps to reduce undesired or dangerous vibration or harmful noise. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 156

• XREF: This application of resonance to instrument soundboards connects to the ‘trees as infrastructure’ essay’s material on musical instrument wood and violin sound.
• ADDENDUM: Resonant soundboard design to strengthen and color sound bears directly on how wooden bodies shape instrument tone, relevant to tree-material applications in the trees essay.
