showing how to soundproof a wall

There are a lot of ways to sound insulate a wall; some methods are complicated and expensive like adding sound deadening material inside an existing wall which also requires a highly skilled and handy person and some techniques are easy and inexpensive, like adding soundproofing material outside an existing wall(Recommended).

It is straightforward and you don’t need to be an expert or highly skilled, follow this guide you will surely soundproof your wall fast and easy.

1. Determine which area you want to soundproof and carefully measure it.

This is one of the most important steps because it ensures that the right amount of material is ordered by doing this, you will cut down the costs as you don’t want any unwanted extra material.

2. Choose the right wall soundproofing foam Panel.

There are a lot of sound deadening foams. Unfortunately, not all foams can deliver what you expected that is why when you choose a foam you need to select the right one that will not only soundproof your wall but also saves you some money in the process.

I recommend Double Thick Acoustic Wedge soundproof foam panel from will do what is required and is very affordable(Click here to check price on Amazon). if you already bought the material that’s okay, move on to the next step)

3. Cut the foam panel according to the size of your wall.

Most panels come in as a  12 or 24 pack cover, depending on the size of the wall the 12 pack foam cover may be too big if that’s the case, cut the soundproofing foam according to the size of your wall.

If the 12 pack cover doesn’t cover the whole area, it would be wise to purchase the 24 pack cover. How do you know how much you need?

Simple, the average scale of the sound insulating foam is one tile = 1 square foot. What I like about Double Thick Studio Acoustic soundproof foam Is that it covers 2 square feet per tile which is 2x more than a usual Foam. This will save you a great deal of money.

4. Implement the soundproof wall foam by using adhesive.

Now that you have you the right size form, it is time to attach it to the wall you wish to soundproof; This will require something sticky to help it stick to the wall.

Regularly Glue could work, but I don’t recommend it for the long-term purpose, in fact, it is better if you use a proper adhesive to help the foam stick.

All you have to do is apply the adhesive to the foam and accurately place it where ever you desire. Don’t get too overwhelmed this is really easy, and you can do it for 2 hours even if you are not a really handy person.
