How to Soundproof a Duplex: What Works Currently

In this article, I am going to share with you the best ways to soundproof a duplex.  I am not going to lie, proper duplex soundproofing can get really challenging and expensive, given that you hire an Acoustic Engineer.

However, in this post, I am going to share with you things that you can do yourself to drastically cut down the noise. without wasting any more time let’s jump straight to it.

Where is the Noise Coming From?

Finding out where the noises and sounds come from is essential because that can save you a ton of money and time. This is a crucial step, so when thinking about soundproofing your duplex it is vital to investigate where the noise comes from and the type of noise it is.

Mass is the name of the Game

When it comes to soundproofing your duplex, adding more mass is crucial to see significant results, the more mass you add the better the soundproofing.

Now, the type of mass you are willing to add depending on whether you own or rent the duplex if you own the duplex you have a pretty good advantage since you can take extreme measures that won’t get you into trouble.

Now that you know that you need to add mass in order to soundproof your duplex, let’s look at some of the ways you can add mass to sound dampen the duplex.

1. Building another Layer of Wall in the Duplex

This is the most effective method,  just like we spoke about how important mass is. Building an extra layer of the wall in the duplex will dramatically cut down the noise.

The only downside to this method it can get a little bit pricey and takes more effort, time and can get you into trouble if you are renting the duplex.

If you are renting, then number two is more applicable to you. If you own your duplex I highly recommend you do this step before moving on to others.

2. Acoustic Foam Panels

In all truth,  using acoustic foam panels will not fully soundproof the walls of the duplex, although it will reduce the noises by a noticeable difference.

An advantage of using acoustic foam panels on your duplex is the fact that they are affordable, easy to install and great for people who rent since this is not a permanent solution.

Acoustic Foam panels will help out a lot but do expect to hear some sound waves but not as strong as before you installed them and when combined with the other methods it can get powerful.

Foam panels are elegant too, you can get ones that match with the interior of the duplex and will instantly improve the aesthetics of the area.

3. Installing Low-Frequency Sound Traps

Low-frequency sound traps also known as bass traps are important to add in your duplex in order to absorb low-frequency sound waves,  fortunately, these are straight forward, all you have to do is place one in each corner of the duplex and let them do the work.

4. Hanging Sound Blocking Curtains

Sound blocking curtains are curtains that are thick and since they contain a lot of mass and thickness they have the ability to block out sounds. Installing these curtains will help combat any noises coming through the window of your duplex.

5. Weatherstripping the Doors

Most people when soundproofing any room, make the mistake of forgetting/leaving the door and this is a huge mistake since all the sound waves can just go through the gaps freely and this defeats the whole purpose of soundproofing the other areas in your duplex.

Fortunately, closing off the door gaps is simple all you need is a soundproof door weatherstrip, and apply that on the gaps, they are self-adhesive and pretty straight forward and can also help prevent the door from slamming.
