- Definition "opposition of a medium to a longitudinal wave motion, characterising the relationship between the acting sound pressure1 and the resulting particle velocity1 sound pressure: [ IATE:1366357 ]" Reference "COM-Term.

- Comment "The specific acoustic impedance, z, is an intensive property of a medium and is the property of a particular geometry and medium. We can specify the z of air or of water. acoustic impedance = pressure/flow andspecific acoustic impedance = pressure/velocitySymbol: zUnit: pascal second per metre, often called the raylSee also: acoustic impedance: [ IATE:1487856 ]Reference: COM-Terminology Coordination, based on:The Australian Office for Learning and Teaching.
