Helmholtz Resonator using voltmeter

  1. Oct 22, 2014 #1
    Hi,

    I am trying to understand how precisely a voltmeter is used to measure the resonant frequency of a sound wave in a helmholtz resonator. Is it simply that the maximum voltage corresponds to the resonant frequency?
    A detailed description or external link would be great.

    Many thanks.

    What voltage? The resonator does not produce a voltage. Do you have a sensor, a transducer somewhere?

    A microphone connected to a voltmeter.
