  • Improving acoustics

If you’re looking to prevent TV noises, music, or your dog’s barking from traveling around your apartment complex, you’re dealing with airborne noise. As the name says, this is the type of sound that travels through the air. That means it probably goes through small holes, under your doors, or directly through the floors and ceilings.

The other type of noise you’re trying to prevent is structure-borne or impact sound. These types of sounds happen when force is applied to the walls, floors or ceilings. So, impact sounds are your footsteps, or kids throwing plastic bricks and dribbling balls on the floor. You can learn more about different types of noise here.

No matter what the source of the noise is, there are some quick and easy steps you can take that will make it at least a bit quieter. You probably know that noise pollution can mess with your productivity and mental health, as well as actually damage your hearing and increase your blood pressure. So, it’s best that you work on suppressing sounds that contribute to the noise pollution you’re already dealing with.

Soundproofing Your Floor Is Easier Than You Thin

Unless you’ve got a millennial living in your basement who has the sleeping habits of bat and likes to party at midnight, the necessity for sound proof flooring usually stems from unwanted vibrational noise that comes from the house itself rather than exterior noise.

Soundproofing a Floor

All flooring projects begin with a subfloor and can be complimented with a soundproofing material.

Flooring underlayments are used to soundproof a floor. It’s important to choose the right type of underlayment for the flooring type.

 

What type of floor are you soundproofing?

The two main floor construction types are timber joists and floorboards, or concrete floors. Concrete floors have a high level of mass. Concrete floors will block airborne sounds (conversation, television). Impact sound (footfall, moving furniture) will still through the floor to the room below. If your floor is timber joist and floorboard both impact and airborne sounds can be a problem.

How To Soundproof a Concrete Floor

Concrete floors carry a lot of mass so are extremely good on their own at soundproofing against airborne noise.

To soundproof a concrete floor you need to add an absorbent layer on top of the concrete to help deaden any impacts.

A simple combination of underlay and carpet works very well.

If needs be you can purchase acoustic underlay which is designed to be extra dense so that more vibrations are absorbed.

Unless you have a serious problem with impact sound then standard underlay and carpet combined with your concrete floor should be sufficient to effectively soundproof a concrete floor against impact sound.
