How to Soundproof a Floor under Carpeting Part 1 How to Soundproof a Floor under Carpeting Part 1
This is the first of a two-part article on how to soundproof a floor under a carpet. Soundproofing the floor helps reduce the noise made when people walk around your home or apartment. This is especially important if you have noise-sensitive neighbors who live below you or want to eliminate some of the squeaking and loud noises that are some time present when living in a home with old wooden flooring.
The first part of this two-part series will focus on measuring the floor area and preparing the floor for the installation of the soundproof barrier. The second article will discuss the process involved in fastening the soundproof material to the floor prior to the installation of the carpeting.
Step 1: Measure the Floor Space
To begin the process of making your floors soundproof, the first step in the process is for you to measure the floor area. Area is the total measurement of the room, which is determined by multiplying the length of the room by the width of the room (area equals length times width). The resulting calculation will give you the room’s square footage, which you need to purchase the soundproofing material for your floor.
Using a tape measure, measure the length of the room, which is the north to south measurement. If the room is not a perfect square or rectangular shape, you will need to take a series of measurements and add them together for the room’s length. Repeat this process for the east to west measurement or width of the room. For example a room that measures 10 feet in length and 10 feet in width has a total area of 100 square feet (10 feet X 10 feet = 100 feet).
Step 2: Purchase Soundproof Floor Material
With the measurements that you obtained in the first step, you need to go to a home improvement center or carpet store to purchase the material for soundproofing the floor. The material can be a fiberglass or foam type material that is easy to manipulate and place on the floor to provide you with the soundproofing that you desire. You should be able to find the type of soundproof material that provides the best sound insulating quality, depending on the type of housing you live in.
Be sure to purchase several square feet of additional soundproof flooring material to give you enough to work with when you begin the installation process.
Step 3: Prepare the Floor for the Soundproof Floor Material Installation
Remove any old carpeting and any other obstructions that may be on the flooring such as nails and staples. You can use a pry bar or claw hammer to accomplish this task. Once you have removed all obstructions on the floor, take a shop vacuum or broom and sweep all debris up before proceeding with the next steps, which will be explained in Part 2.
