How to Soundproof a Basement Ceiling?

When you make an unfinished basement your living space, the sound effect from upstairs on those living downstairs or vice versa is generally overlooked. The sounds coming from a TV upstairs can sound amazing to you if it’s a Sunday or you are in a good mood. But not when you are seriously working on something in your basement office. The same goes true if you try to sleep on the first floor and there is a lot of noise coming from the TV in the basement.

Aren’t there any ways to solve these noise issues? Of course, there are. Here we have come up with ways to soundproof the basement ceiling of your home. Before diving into it, let’s find out the areas to soundproof in a basement.


Areas to SoundProof in a Basement

Your basement needs soundproofing, but which areas should you start from?

Basement Ceiling

One of the biggest sound contributors in your home is the basement ceiling. The sources of sounds could be vibrations from footsteps, dropped items, and the list goes on. Seal any cracks, holes, and gaps on the floors (subfloor) above your basement. Doing so will ensure that these minute crevices are not allowing the noises to sneak into the basement.

Add new mass layers to the soundproof basement ceiling. Form these new layers with materials like mass-loaded vinyl, drywall, etc. for basement sound insulation. You can also consider getting soundproof panels installed for added security as it will help in noise reduction by absorbing and reflecting sound.

Doors and walls

If you think that simply closing your door will keep away the noise from the basement at bay, you need to rethink. A soundproof basement is the ultimate solution. It also comes with additional privacy, especially when you have decided to set up the home studio or office for which you need minimal distractions. Add door seals or sweeps to soundproof the doors and for closing the gaps between doors and staircase/floors. Door sweeps or seals are solid and dense so that the sound waves cannot easily pass through them. Adding a soundproofing foam is also a good idea.

As far as basement walls are concerned, add soundproofing boards to minimize the flanking and mechanical noises coming from the basement. You can even opt for small sound barriers, as small as less than half an inch thick, for basement sound insulation. If you are creating separate rooms in the basement and creating walls there, follow the decoupling process. It lets you leverage sound isolation systems. Need more to soundproof the basement ceiling?

Floors are also one of the areas impacted by the noise coming out from the basement. This happens especially in homes that have unfinished basements with concrete slabs.

What you can do here is install an absorption floor between the concrete and the final floor. The other thing you can try is placing flooring underlayments under carpets.

HVAC and Pipes

Check the positioning of the HVAC system, plumbing pipes, and furnaces of your home. Consider their level of reverberations and how these transfer through the basement walls.

Insulating pipework addresses the noise and sounds before they can transform into the noise in your home. Also, you can fill the space between the walls and pipes with different soundproofing materials.

How do you install soundproofing on a basement ceiling? 

It’s time to silence the sounds coming from the basement ceiling. Here are the steps –

Seal all cracks in the subfloor

Start by sealing the gaps and cracks in the subfloor above the basement. You can use a ladder and a calking gun. Gather tape measure, utility knife, and straightedge to score. Now, cut the drywall sheets into strips and fill the cracks and cavities.

After sealing the subfloor, install the first layer of drywall. Want the best results? Use soundproof drywall. After securing the first layers, add the second layer of drywall to create a dense barrier against noise.

Install insulation

Acoustic insulation like fiberglass or mineral wood are effective basement sound insulation method. Distribute the insulation evenly between the joists to make the basements quieter.

Add a resilient channel 

Install a resilient channel between the drywall and the framing studs. These specialized metal furring strips reduces the amount of vibration occurring through the wall and hence reduce the sound transmission.

Install the final ⅝” thick drywall

Install the final ⅝” thick drywall to create a barrier against unwanted sounds. This additional mass further enhances the soundproofing effectiveness, ensuring minimal noise transfer between floors.

Some Guidelines for Sound Proofing from Nation Building Code – Alberta Edition 

Soundproofing basement ceiling materials must be used for every dwelling. This is done to minimize the noise levels between units –

  1. Sound absorbing materials of at least 150mm to fill joist spaces.
  2. Placing 12.7mm thick gypsum board on the ceiling on both sides of the wall.
  3. The ceiling should have a sound transmission class rating of at least 43 or a separating assembly and adjoining constructions. The combination of both of them should give an apparent transmission class rating of at least 40.
