Four Aspects of Sound Isolation

Four Aspects of Sound Isolation

When it comes to sound isolation for your recording studio environment, you only need to keep four things in mind.
Mass: The first line of defense in soundproofing
Decoupling: Break the connections that sound vibrations use to get from one side of a wall to the other.
Distance: Gain better overall sound reduction and increased low frequency isolation.
Absorption: Control mid to high frequency and also damp the individual wall panels.

Acoustics for recording or theater playback

Small room acoustics for recording or theater playback

A typical small recording room is going to be made in a room available in the home. There are magnified acoustical issues with small rooms that are not issues at all with medium to large rooms, rooms of 1500 cubic feet or larger.

Let us use a room of the dimensions, 12 feet in length, 10 feet in width and 8 feet in height.

The first thing we want to do is to understand how sound is going to be in this room, how it is going to interact with the space as sound becomes the small room acoustics.

Acoustic isolation / sound proofing


Soundproofing a home recording studio

Soundproofing on “Holmes on Homes”

This is a good example of what is called “isolation” and how to do it. Isolation is often confused with acoustical treatments. This has always been incorrect.

The sponsor is Quietrock(r) so thier product is used in this video. For your home theater or studio, standard sheetrock can be used with very good results.

 

Look closely as this video plays. After the sheetrock has been removed from the wall you can clearly see two(2) different stud framing sides to this wall. This is a simple “decoupling” technique that will give you a better rated wall then a simple one row stud framed wall.

Sound proof window plug

How to build a window plug and stop sound leaks

This is a good fit as to the importance of doors and windows.


After all is said and done, windows and doors are part of the vertical few that are the biggest sound leak areas your recording and home theater construction will suffer at.

What the video presents is good general purpose information as it relates to sealing up windows and doors to prevent sound or air leakage. It at least gets the builders mind on the idea! And this is an important mind set to develop. It shouldn’t be thought of along the way, it should be ever-present.
