87Elastic modulus — An elastic modulus, or modulus of elasticity, is the mathematical description of an object or substance s tendency to be deformed elastically (i.e., non permanently) when a force is applied to it. The elastic modulus of an object is defined as… …
88Acoustic 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… …
