Acoustic Treatment Layout Blueprint (Should it cover the ceiling and floor or just walls?)

Your theatre room acoustics treatment will not be done only by installing acoustic panels on the side-by-side walling.

You will have to cover the ceiling reflection areas and the floor reflection areas too.

The complete treatment layout will be side-by-side walls,  ceiling, and floor. It means that you will have to cover every hard surface in the room that can reflect sound. Also, you have to install soft sofas too.

If the room floor’s hard surface is visible then it will increase the overall echo of the sound. 

The problem with the floor is that you can’t install acoustic panels on it. The floor will not look good with the acoustic panels. 

 The sidewalls and the ceiling can look fabulous with the panels.

But one simple and creative thing that you can do for the floor is to place a soft rug on it to cover the hard surface of it.

This soft rug will absorb the sound rays and will stop the reverberation of the sound.

That must be dense and soft to absorb the sound effectively.

Bass Traps For Home Theater

These panels are the same as others, no different in shape and material.

The only difference in these bass traps other than other panels is that these panels have special areas for installation. 

Bass traps can be installed in those areas where two surfaces meet with each other like wall corners. You will have to place acoustic panels in these corners to trap the excessive bass and hence they will be called bass traps.

They kill the excessive reverberation of the bass and hence refine the overall base of the audio and deliver the pure form of the bass.  

You can also DIY or buy decorative panels for corners. I just wanted to let you know that bass traps can only be installed at the corners.

For the best bass, you should consider the best Subwoofer as well. After that, you will get the most realistic audio that can make your friends get jealous.
