Hi there, I am currently looking into Active Noise Control and its potential applications as part of my Honours for Industrial Design. From what I have looked into Active Noise Control, it seems it is easier to achieve if you have direct access to the source that is creating the noise. So my project question is if surface transducers (or maybe speakers) were put on an object producing noise (such as a kettle or even a power tool) and have played the inverted sound of the object via them being connected to an ANC circuit, and microphones to pick up the objects noise in the first place (which would also be placed on the object as well), would you be able to get the noise dampened?
I came across this circuit on Instructables for Active Noise Cancelling Headphones-

Would it be possible to adapt this circuit to suit my project question (ie have the surfaces transducers as the outputs instead of the headphones)? Or are they simply too different?
Thanks for any feedback
