- Comment "It allows us to calculate acoustic power, intensity and the reflection and transmission at boundaries.Not to be confused with:specific acoustic impedance [ IATE:1075739 ]The specific acoustic impedance is a ratio of acoustic pressure to specific flow, which is the same as flow per unit area, or acoustic flow velocity, u. So we define acoustic impedance Z and specific acoustic impedance z.Thus:acoustic impedance = pressure/flow andspecific acoustic impedance = pressure/velocitySymbol: ZUnit: pascal second per cubic metre (Pa·s/m3) or the rayl per square metre (rayl/m2)Reference: COM-Terminology Coordination, based on:The Australian Office for Learning and Teaching.
