My name is Alex Genadinik. I've been in Elearning since 2014 and have over 250,000 students. Here is my Udemy teaching profile.
In this article, we'll cover:
1) What is acoustic foam.
2) Other options if you don't want to use acoustic foam.

I am also available for Elearning coaching to help you plan, create, and promote your course.
Acoustic foam is foam that helps you get rid of echo in your recording. When you record your courses, the sound waves bounce of the walls and if they keep bouncing, they will cause your audio to have an echo-like effect, which will decrease your audio quality and with that the quality of your courses.
If a sound wave hits foam, it won't bounce off it. This way the foam helps you decrease the echo in your audio. Foam is relatively cheap and you can attach it to the walls of your recording studio.
The main problem with foam is that it's ugly and takes a lot of space on your walls. If you live with anyone, they are unlikely to want it on their walls.
A workaround is to buy an area rug for the floor. The rug will also help to get rid of the echo and some people might aesthetically prefer it to foam.
Here is a page on this website which lists all my best courses with discounts.
Creating courses can take weeks or months. If you don't want to create courses on your own and get courses overnight, course licensing is possible.
With course licensing, a person can get courses to sell overnight. I offer a few licensing options for my 125+ courses.
I offer the course licensing option through which you can license my courses to sell on your website and keep 100% of lifetime revenue.
If you need additional help, I offer the Elearning franchise option which comes with my courses to resell, a website, and coaching in one package.
