Resonance can amplify desired sound or cause harmful machine vibration

Evidence

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
