Soundproofing materials can be confusing, so we’re going to take some time over the next couple of days to take a closer look at several of the most popular and talk about why they work (or not).
Vinyl materials, also formally known as mass loaded vinyl of MLV, are often used to block noise. Mass loaded vinyl works by adding density (or mass, or weight) to an area, making it hard for sound to pass through.
The problem with using MLV in soundproofing is that it really doesn’t weigh a lot at all - maybe 1-2 lbs per square foot. That means MLV will work well if you have a small sound problem, but not if you’re fighting a very loud noise, or one with a strong frequency.
If you’re lucky enough to have a speedboat, yacht, or cabin cruiser than you’ll probably want to take the time to soundproof the interior just a little bit. Who wants to be aroused from a seaborne nap in the cabin by the sound of the incredibly loud marine diesel engine or by the sound of the waves slapping on the side of the hull? Why not enjoy your time on the sea as much as possible?
Soundproofing a boat is easier than you might think. The main source of noise is, of course, the engine compartment. With that in mind you’ll want to adhere some mass loaded vinyl to the inside walls of the engine compartment. You can get it to stick by using some sort of contact cement or, for added effect, another acoustical product like Green Glue. Whatever you do, make sure the products you choose to use are waterproof.
To finish off the project you’ll simply have to apply some acoustical caulk around the seams and perimeter of the vinyl. Make sure you let your work dry completely before putting the boat in the water. The soundproofing effects garnered by just this little bit of work will prove astounding.
Do you have an old computer that makes a ton of noise? Believe it or not, you can soundproof your computer as well and the process is incredibly simple.
You’ll start by opening your computer so that you can work with the CPU case or cover. You’ll want to take a small amount of mass loaded vinyl and glue it to the inside of the case so that it covers as much area as possible. It is important to make sure that you do NOT cover the areas that usually allow your processor ventilation system to work. Take a piece of vinyl and glue it to the bottom of your computer case as well (on the inside or outside).
Before you know it you will have drastically reduced the amount of noise your computer makes. Just make sure you are carefully when taking your computer apart so that you don’t cause a static charge that will damage your processor. If you are nervous about working with your computer ask something with a bit of technical experience to help you take it apart. Better safe than sorry!
