I don’t think active noise cancellation can work like you are hoping. Active noise cancellation works for a target location (your ear’s location) not for a general area. It works by wave superposition cancelling out the wave for the target location. But the waves won’t cancel at any other location. I think you want something more like metamaterials that can be put on walls for homes and offices.
