Soundproofing – What materials should you invest in?

09 Jul Posted in Family


For a wide variety of reasons, soundproofing is a great investment. Mainly because of privacy matters, many choose to make such investments, and surprisingly, they are not as expensive as they might think. However, it is necessary to do some research, read reviews, and decide what materials work best for this type of home improvement. These investments might be highly beneficial for musicians (stop noise complaints from their neighbours) as well as for families who want to offer a peaceful indoor environment (repel outdoor noise). However, below are some general considerations on soundproofing and the materials one must invest in for this purpose.

1. How does soundproofing work?

Soundproofing has the main purpose to prevent outdoor sounds from coming in, and to prevent indoor sounds from going out of a room. This means that you basically must prevent the vibration’s travel through walls and floors. There are several ways in which one could soundproof their property: decouple surfaces, dampen sounds, add mass and absorb sounds. Each technique requires different materials for soundproofing. Below we will analyse two of the most facile soundproofing techniques.

2. Materials that absorb sounds

The main technique to soundproof a room by absorbing sounds is filling in any types of gaps from where sound might enter (or leave) you room. This technique is used because sound travels faster through the air, rather than through other materials. For this purpose, it’s advisable to invest in the following types of materials, known as acoustic sealants:

  • Acoustic caulk – it oftentimes comes in easy-to-use tubes and you can easily apply it in all areas from where air might enter your home. Corners, cracks in the walls and even around ventilation holes. Acoustic putty is another option homeowners have, because it’s a dense air sealant.
  • Door seals and door bottoms – install such products on your doors. They will prevent sound to travel from any potential small gaps, solving the problem of airborne sound.

3. Materials that add mass

As we previously mentioned, adding mass is yet another effective way to soundproof a property. Because sound travels through vibrations, it is necessary to add mass to walls, let’s say, to prevent it from entering or leaving the house. Adding dense materials to surfaces acts as a great sound repellent. Some great materials to soundproof a house are:

  • Mass loaded vinyl – it’s a material generally used to block sound from travelling through walls, ceilings, pipes, and so on. Many use them to manufacture curtains or window covers from this amazing material.

As you can easily notice, with minimum investments one could soundproof their property in a highly efficient manner. Make sure to document yourself well before bringing some improvements, because the quality of the materials you use will certainly influence how good they will soundproof your property. Stopping noises from leaving or entering a property is more beneficial than many might think, especially for those who appreciate greatly their privacy and peace of mind.
