  • impedance matching

    the technique of choosing or adjusting electric circuits and components so that the impedance of the load is equal to the internal impedance of the power source, thereby optimizing the power transfer from source to load.

  • acoustic ohm

    the unit of acoustic impedance, equal to the impedance of a medium in which a sound pressure of one dyne per square centimeter produces a velocity of one centimeter per second.

  • mechanical impedance

    impedance (def 2).

  • acoustic impedance

    the total reaction of a medium to the transmission of sound through it, expressed as the ratio of sound pressure to particle velocity at a given point in the medium.

  • acoustic reactance

    acoustic impedance caused by the inertia and elasticity of the transmitting medium.

  • acoustic resistance

    acoustic impedance caused by the internal friction of the transmitting medium.
