How to Reduce Sound in a Building

Noise is any unwanted sound. It could be the sound of traffic running down the highway, a video playing loudly in a room where you’re trying to have a conversation or hearing the conversation in the room next to yours. Noise pollution can disrupt your work, or sleep. There is noise everywhere, but there are ways to eliminate noise pollution. Below are some changes that you can make to your house to help eliminate the amount of noise.

To solve noise problems, first, you need to understand a bit about how sound travels. When an object vibrates, it creates wavelengths called sound. Treble consists of short wavelengths, and bass consists of long wavelengths. Treble bounces off most hard surfaces. Soft materials tend to absorb treble wavelengths. Bass resonates with hard surfaces and is not as easily absorbed by soft items.

Most walls and ceilings do a poor job of effectively controlling noise. Walls are created using drywall with a blank space filled with air. Noise can travel right through the walls. If walls are parallel to each other than soundwaves are likely to bounce back and forth between walls, causing an echoing effect.

One way to solve this problem is to install a noise barrier wall. The construction of these types of walls can vary, but they are all designed to help reduce the amount of noise comes into a room. Some use a layer of polymer instead of the standard drywall. The polymer material reflects about half of the noise.

Fiber Cement siding is better than aluminum, wood or vinyl at reducing noise. Spray foam insulation blocks noise better than fiberglass. Some construction workers use a method of sandwiching concrete and drywall to reduce the amount of noise. Acoustic panels can also be placed on walls to help reduce the noise. For best results, the noise reduction coefficient needs to be .85 or above. No matter what method you choose, you need to make sure that the walls have no cracks or holes. A hole in the wall allows noise can move freely.

Noise can travel freely through cracks in windows and doors too, so it is important that everything is sealed tightly. Windows installed as a double or triple pane to help reduce noise. If installing new windows is not an option, install an acoustic seal. Use chalk to seal up any creaks in the window and buy heavy noise canceling curtains.

The doors should be a solid wood core door. The door needs to be sealed as well to stop the noise. Even a little crack can transmit a lot of sound to other rooms of the house.

The best floors to have in a house are cork or concrete. For hardwood flooring, floating hardwood leaves a gap between the actual flooring, helping to stop the sound. Adding carpet or padding to the floor can also help absorb sound. To help battle sound outside you can plant a row of trees or hedges. These plants can act as a natural barrier to sounds entering your yard.
