![]() Install extra insulation if you can easily access the area between the ceiling and the floor above it, or the walls of your basement blown insulation is the simplest alternative because it does not need the removal of structures. It will also reduce the amount of noise that may be heard in the space above or next to the basement. Because insulation absorbs sound waves, it can help reduce the amount of noise you hear coming through the floor above you or the walls of your basement. Insulation is a good technique to cut down on sound transmission. Video: Basement Ceiling Soundproofing – 4 DIY Ways to Do it Cheap! Keep in mind that the denser the drywall, the better the soundproofing properties (what is drywall – read here). We recommend utilizing sound deadening drywall and adding Green Glue soundproofing solution to the back of the drywall before installing it for the greatest effects. It adds bulk to the room, which helps to decrease sound transmission through the ceiling and walls. ![]() Drywallĭrywall may also be used to soundproof a room. Remove the adhesive backing’s cover and place it on the surface of the area you want to seal. Cut lengths of weather stripping to size after measuring the area where it will be used. Acoustic caulking from Green Glue is a polymer that helps to minimize vibrations generated by soundwaves, reducing noise transmission. We recommend using either Green Glue ( official website) acoustic caulking or weatherstripping to fill any gaps. Soundwaves travel through gaps, so closing them will assist to stop the flow of undesirable sounds. If there are any gaps in your basement’s ceiling, walls, or around the windows, fill them up. We’ll go through some of the different ways you can prevent soundwaves from going out or into your basement in the sections below. You may use several soundproofing techniques once you’ve determined the type of noise you want to eliminate. This is the type of noise you hear when someone walks overhead and the sound of their footsteps can be heard in your basement, or when someone bounces a ball into the basement ceiling and you can hear it through the floor. When an object comes into contact with another structure – including a person’s footsteps on a floor – soundwaves are generated, and these soundwaves pass straight through the structure hence, impact noise is also known as structure-borne noise. Instead of air, the medium through which impact noise travels is a solid structure. The sound then passes through the solid object and out into the surrounding space. Soundwaves move through the air until they hit a solid object like a wall, floor, or ceiling. The medium in the case of airborne noise is, as the name implies, air. Soundwaves are created when someone or something generates noise, and these soundwaves are taken up by a medium. The most frequent sound you hear is airborne noise, which includes things like people chatting, TV noises, and music. Plan out the inner basement walls, HVAC, and plumbing, as well as soundproofing materials that dampen or absorb sound, to prevent sound from traveling in the wrong direction. Moreover, by decoupling the levels, you may stop the pathways mechanical sound vibrations can travel via joists and supports.īecause they are indirect, the most challenging paths are those where flanking noise can travel (we explained what flanking noise is in our article: How to Soundproof an Air Vent). To soundproof a basement, you must use added mass to prevent or absorb airborne sound waves, we will explain this later. The higher the STC the more effective it will be to soundproof the different parts of your basement. Once you’ve determined what you want to achieve, choose the STC ( Sound Transmission Class) that best fits your needs. ![]() Ultimately, if you’ll be making noise at godly hours or late at night, you should remember to increase your soundproofing. It’s fine to go a little crazy, but if your needs aren’t so great, why waste money? The question is: how loud can you get? Maybe you will be using your basement as a home theater or a drum room. Soundproofing levels may be measured, so understanding what you want to accomplish is definitely important.
