Acoustic Impedance - an overview ScienceDirect Topics

WitrynaAs opposed to constant voltage circuits, in AC circuits the impedance of an element is a measure of how much the element opposes current flow when an AC voltage is applied across it. It is basically a voltage to current ratio, expressed in the frequency domain. Impedance is a complex number, which consists of a real and an imaginary part: Witrynaratio of specific heat of a gas: ... may be measured by connecting the probe to a manometer or U-tube and then determining the water displacement as the immittance device air pressure dial is rotated. If the SI unit of deca pascals (daPa) is used, an appropriate measuring device must also be used.
