Hi, I'm looking for an equation which links capacitance to the phase difference between two microphones (picking up audio from a loudspeaker). (the speaker gives off a signal at 3 kHz).
My experiment, at the end of the process, was devised to be linked into the setting of microphone positions on a kick drum of a drum kit. For example, if two microphones were used, there would be a phase difference between the two signals into the mixing desk.
As such, I’m representing an approximate frequency of the drum kit with a signal generator attached to a loudspeaker for ease of use in a physics lab. Therefore, I was hoping that using a capacitor in series with microphone A (closest to the speaker), I could add a phase shift to produce constructive interference and therefore remove the phase difference between microphone A and microphone B.
I was therefore hoping that there may be an equation linking either phase difference, distance from the loudspeaker, frequency or wavelength to the capacitance required to shift the phase of A to produce constructive interference.
Any help apprectiated,
Cheers
