If you listen to music in a room that emphasizes the bass frequencies then chances are you’ll compensate for this by reducing the bass. The problem is when you take your recording out of that room, the sound or mix is probably going be bass ‘light.’
Studio Acoustics progresses by looking at acoustic principles. Sound is transmitted by sound ‘waves’ of different lengths, shapes, and intensities. Alan looks at how waves behave in an enclosed space and how they reflect or get absorbed by hard surfaces.
The three main forms of sound behavior are examined: Sound Isolation, which is how you can stop your sound going out of the room and also stop sounds you don’t want from coming in. Sound Absorption, which is how sound can be soaked up like a sponge and so deadened. Finally, Sound Diffusion, which is how sound waves are broken up and dispersed. A small room without some form of diffusion will generate what are called room modes, which are build-ups of waves that bounce back and forth without being broken up or diffused. The fluttery pinging sound you hear in an empty room with symmetrical walls is a very easy to hear manifestation of this.
Studio Acoustics then looks at what you can do to improve or enhance the sound of your recording environment. The producers of the series actually constructed a purposed built studio for the making of the program and you get to see the construction process from start to finish including an examination of such things as floating floors, non parallel walls, window double-glazing, lighting, doors, and more.
Although Studio Acoustics takes a thorough look at how sound behaves in a typical recording environment you don’t have to be on the point of building your own recording studio to make use of this information. Alan and acoustic team offer a lot of simple practical advice that can be applied to a bedroom or garage recording space.
Finally, Studio Acoustics looks at how best to place your equipment. This is a vitally important subject. Alan shows how monitors should ideally be placed at ear level, in an equilateral triangle between the speakers and yourself. And he tells you why!
Studio Acoustics and acoustic treatments may not be the most glamorous of subjects but at least part of the reason great studios have produced great records in the past is that they both encourage and help produce great recordings to begin with, and then they let the mix engineer and producer mold those recordings into tracks that sound good in
