Soundproof your floors to overcome two types of noise


There are two types of noise that silencers on your floor can counter: impact noise and air noise.


The two methods of sound transmission must be considered together to ensure that the maximum amount of noise is reduced.


Impact noise

Structural noise is caused by vibrations, usually when an object hits the floor.


This can be a ladder, dragging furniture, vibrating utensils, or dropping something heavy on the floor.


The falling weight creates a very percussive sound that vibrates on your floor

Lowering the weight creates a lot of noise impact


Unlike walls, floors are an important factor in building sound pollution due to noise and traffic frequencies.


Impact noise has a greater impact on the floor below than in the room where it vibrates freely through the ceiling.


Soundproof a floor reduce the impact of both above and below noise.


Air noise

This type of noise spreads through the air and includes sounds such as music, voices, television, and barking dogs.


Again, floor insulation solutions help you keep this noise in your room from disturbing your neighbors or roommates on the ground floor and to prevent noise from below penetrating the floor.


How To Make Soundproof Floors: Where Should I Start?

If you've recently built a house or remodeled an attic or basement, now is a great time to keep the floors soundproof while your beams and floors are still exposed.


However, it is perfectly possible to make your floors soundproof - no matter what they are made of - in a pre-built house or apartment.



Most floors are made of wood or concrete.


The concrete floor perfectly protects the air noise from flowing.


However, a sound such as a strong footstep can cause vibrations and create a crash sound that is completely diffused.


Many new buildings now use concrete in wood for floors because of their strength and noise reduction.


For example, part of the specification for building The Shard in London is that all 42 floors are fully sound proofing.


They achieve this by using insulating material for the acoustic screed and the (very) heavy concrete floor.


For those of us who don't live in The Shard (or in a concrete apartment), chances are we have hardwood floors.



They're not very good at stopping noise or vibrations in the air, so they'll need more work to isolate.


How can you make wood flooring soundproof?


Let's have a look.


Wooden floor

There is usually a hole under the wooden floor where the sound echoes slightly inward and travels significantly between the floors.



To have a soundproof wooden floor, you have several options, including:


Sound insulation under floorboards.

Basic floating.

Acoustic pillow.


These methods can be combined for best results. Below are other ways to make your hardwood floors soundproof.


The wooden floor also makes a lot of noise if you walk on it in high heels. If this is your problem, check out our article on How to Soothe Your Heel, or check out our article on How to Walk Calmly.


Concrete floor

Concrete floors contain a lot of mass and are therefore very much protected from airborne noise.


However, they sent out a clashing sound quite well. If you've lived under a concrete floor before, you're probably familiar with the morning your neighbor knocks, shakes on the floor.


To make a soundproofing on a concrete floor, you need to add an absorbent layer to reduce impact. A simple mat and rug combination works really well.



If necessary, you can purchase very dense acoustic pads to absorb more vibrations.


Unless you have a serious problem with impact noise, a standard mat and rug or mat combined with your concrete floor should be sufficient to effectively insulate the floor from impact noise.
