This post is part of a series called How to Build a Home Video Studio.
How to Plan Your Home Video Studio
How to Refine the Sound of Your DIY Video Studio

In the introduction to this series, we took an overview of everything you need to set up a home video studio. In this tutorial, you'll learn how to treat the floor of your studio to reduce reverberations and improve your sound quality.

Cut Reverb With Carpet

Any hard surface reflects sound and causes echo. The room I'll be using has hardwood floors, and wood floors reflects sound like crazy (concrete is bad too). That's one reason we'll start with the floor. The second reason is of course convenience: I want to set the carpet first and then add stuff in the room. As you can see from the comparison in the video below, a carpet makes a huge difference to the sound.

 

Now, apart from the carpet thickness, there is something else to consider.

Carpet Color

If you pay attention to the beginning of the video (until about 01:10) you'll see the image has an orange tint. But everything after that point doesn't. That's because the hardwood floor reflects light with a color cast. Once I put down the carpet, which is a darker ivory color, that orange tint disappeared.

Be careful when choosing the carpet. If you get a colored one you might end up with bigger problems than room echo. Pick a neutral colored one, preferably light gray or ivory. For reference, this is the carpet I'm using. It looks more beige in the website photo than it really is.

How to Set the Carpet

Now, setting the carpet is a pretty easy task. As I said in the video, I didn't glue it to the floor because it usually leaves residue. Depending on the size of your room and the kind of floor you have, Hold It tape or similar products can help keep rugs and carpets from sliding. Mine will be kept in place nicely by the desk.

 

The Next Step

Now that the carpet is set, let's finish the acoustical treatment by adding panels and bass traps. That's coming up in our next tutorial.
