Helmholtz Resonator using voltmeter

Click For Summary
SUMMARY

The discussion centers on measuring the resonant frequency of a Helmholtz resonator using a voltmeter. It is established that the resonator itself does not generate voltage; instead, a microphone or transducer must be employed to convert sound waves into electrical signals that can be measured. The maximum voltage observed on the voltmeter corresponds to the resonant frequency of the sound wave produced by the resonator. Understanding this relationship is crucial for accurate frequency measurement.

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?
