Sound doesn't travel in a vacuum. Bass traps work by eating up the energy in pressure waves that hit them, there's a lot of waves that don't hit them. Which means that bass traps are only good for minimizing resonances inside an enclosed room, not to stop bass from reproducing through walls or materials.
