Acoustic insulation in University of Alberta Farm, the cavity half of the job

Acoustic insulation is one lever of four. Mass, decoupling, damping and sealing are the others, and a cavity full of good batts behind an unsealed perimeter still leaks sound. We would rather explain that first than have you pay for batts and be disappointed.

Acoustic Insulation University of Alberta Farm Edmonton: your questions answered

Can you add acoustic insulation to a wall that is already finished in Edmonton?

Not without opening it. If the wall is staying closed, the practical route is adding mass and damping on the room side. We will tell you what that realistically achieves before you decide.

Can you stop footsteps from upstairs?

Partly. Insulation in the joist space handles the airborne half — voices, television. Footsteps are impact noise through structure, which needs decoupling or floor treatment above. We explain which half we can address from below.

Will it stop footsteps from upstairs?

Not on its own. Footsteps are structure-borne — they travel through the framing, not the air in the cavity. That needs decoupling, such as resilient channel, with the insulation as one part of the assembly.

Will this soundproof my media room?

For dialogue and mid-range, yes, meaningfully. Bass passes through cavity insulation almost unaffected because it moves the structure. If nobody upstairs should hear the movie, the assembly needs mass and decoupling too.

Do I need to seal as well, or is the insulation enough?

You need to seal. A perfectly filled cavity behind an unsealed perimeter still leaks sound — gaps at the floor and ceiling and back-to-back outlets carry it straight past the batts.

What should I realistically expect afterwards?

Conversation next door becomes an indistinct murmur rather than words you can follow, and television becomes background. It will not be silence, and bass will still come through.
