It does this through its open-celled structure, which traps sound waves and prevents them from bouncing off a flat surface. This is because acoustic foam doesn’t block sound, but rather it “improves” acoustic quality. However, bear in mind that it should never be used on its own, but should complement other soundproofing materials. Acoustic foam is ideal for this, and it’s essentially the stuff used in recording studios. MLV is a popular product in all kinds of soundproofing jobs.Īlong with sound deadening, you’ll also need a material that reduces echo and reverberation, as these both contribute to overall noise levels. This is helpful because the heavier an object is the more difficult it is for sound waves to pass through it. It’s also very dense, which adds extra weight to the box. The technical term is deadening, as it doesn’t vibrate, which is how sound waves pass through a solid surface. This means that when a sound wave comes into contact with it, it simply dissipates. In short, it’s what’s known as limp mass. Mass loaded vinyl is one of the best soundproofing materials in almost any situation, as it’s specifically designed for this kind of job. So what products should you use? Here are my top suggestions: Dense mass makes the box heavier, meaning sound waves aren’t able to vibrate through it, and acoustic treatment helps to reduce echo and reverberation. What soundproofing materials do I need?Ī soundproof box requires both dense mass and acoustic treatment, as this is the most effective combination that covers all issues. Green Glue is ideal for this kind of project because it not only seals gaps but also dampens sounds escaping through the cracks. Most of these items should be fairly easy to get MDF should be available from your local hardware store, and you can get Green Glue (Amazon) online. Make sure you have everything on this list before getting started: Materials you’ll need for a soundproof generator boxįor this project, you’ll need a few standard building materials, some tools, and then some specialist soundproofing equipment. I’ll explain these steps in more detail below, but first I’ll go through a list of the materials you’ll need, along with which are the best soundproofing products to use in this kind of project.
