String resonance of a bass guitar A note with fundamental frequency of 110 Hz. Computed with from sampled sound with https://sourceforge.net/projects/amoreaccuratefouriertransform/ .

The first three resonances in an open cylindrical tube. The horizontal axis is pressure.

The first three resonances in a one end open and other end closed cylindrical tube. The horizontal axis is pressure.

Acoustic resonance is a phenomenon that consists of a given acoustic system amplifying a sound whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies).

The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter acoustic resonance can occur at frequencies outside the range of human hearing.
