Thank you all for your suggestions.
Here is one big answer to all of the responses:
Yes, we have considered using electrical apparatus involving opamps, resistors and pentiometers, to alter the cancellation of certain frequencies, but we need some guidance in the area.
Yes, thank you...
Some background information:
I am trying to cancel audio signal/noise in an enclosure I have constructed.
I have two identical woofers positioned opposite each other in the enclosure.
I have a very accurate sound level measurement microphone positioned between the two drivers.
I am using sound...
My colleagues and I are building a phase adjuster for LFN (Low Frequency Noise) audio signals. Since we would like to be able to adjust a range of signals that encompasses a range of around 50-400 Hz, an op amp-driven, analog solution would not be economical, nor efficient. Since we need to be...
