Acoustic resonance — is the tendency of an acoustic system to absorb more energy when the frequency of its oscillations matches the system s natural frequency of vibration (its resonance frequency ) than it does at other frequencies. A resonant object will probably… … Wikipedia
Acoustic impedance — The acoustic impedance Z (or sound impedance) is a frequency f dependent parameter and is very useful, for example, for describing the behaviour of musical wind instruments. Mathematically, it is the sound pressure p divided by the particle… … Wikipedia
Strouhal number — In dimensional analysis, the Strouhal number is a dimensionless number describing oscillating flow mechanisms. Often, it is given as:: mathrm{Sr}= {f Lover v} where Sr is the dimensionless Strouhal number, f is the frequency of vortex shedding, L … Wikipedia
