Yes, its the length or, indeed volume, and any restriction which determine its efficiency at producing a wave form in the correct phase (180deg) and at sufficient amplitude. A mouse fart even if 180deg out of phase would not cancel out an elephants fart. So I guess that the pipe has to be of similar bore and you need to tailor the length to the frequency you wish to cancel out. And thats where your maths comes in.
