Can't be done because the sound from source propagate as a spherical wave. To cancel it with destructive interference you would need to make a wave which focuses to the source and would only work if you are in between the noise source and the counter wave generator. Unfortunately to make a plane wave you would need infinite number of point sources or need the counter source further away. An alternative is to track listener and cancel the noise around that region but you would only be able to do that with very low frequencies with wavelength larger than distance between your two ears.
