Hi!
I'm a college student and I'm running an experiment to measure the acoustic resonance curve of a Helmholtz resonator and to measure the acoustic resonance curve in an open-open tube and I just found this thread.
The app is being used and I can't understand how to best position the speaker and microphone for the experiment.
Using only a phyphoxed phone close to the mouth of the bottle used as a resonator, the curve cannot be obtained?
Is it necessary to place a speaker reproducing the frequencies generated by Phyphox in the bottom of my resonator and a microphone, located in the mouth of the bottle, that can produce the curve by another app experiment?
Sorry for my bad English, it's not my first language.
