Want to cancel noise from neighbor's shower pump
Question

Answer
Although attaching devices to the walls to cancel out noise is possible, unfortunately there are no such devices available commercially. The only real solution to the problem at this time is to use acoustical materials to to walls that will reduce the sound coming through them.
If the electric shower pump is accessible, acoustical insulation could be put in its enclosure.
Sorry that I can't offer a better solution.
