SOUND 101: The “Golden Acoustic Ratio”
From all the research I have been doing for the past decade, here are a few ratios that I have found that are suitable room dimensions for recording, they are:
1 x 1.6 x 2.56 (famous golden ratio) – invented by the Greeks &
.62 x 1 x 1.62 – sound engineers use this.
H = Height of ceiling, W = Width of room, L = Length of room
For example, if you have a room that is 8 feet high, you multiply the 8 to 1 x 1.14 x 1.39 (1st ratio) which equals =
8 ft x 9.12 ft x 11.12 ft
I know what you might be saying, what if I cannot build my own room what do I do? Here are a few suggestions:
1. If you have a large room where the ceilings are high and the walls are far apart, you don’t have to worry about reflection, but everyone else,
2. Use false walls and ceilings. In small studios, like most project studios, builders would make the room to the size they want. I consulted many sound engineers and they reaffirmed my beliefs that false walls and lowered ceilings can drastically improve room acoustics.
3. Buy studio foam and room treatments. Do not use egg cartons or mattress topper, buy studio foam. What it does is that it absorbs some of the energy from the mid-range and higher frequencies, not bass! You need at least 2 inch foam, for the ceiling, side walls, and the wall behind your monitors. You might say, man I don’t want to mess up my living room with all this sh#t! That is why make it removable. Just like a picture frame. Same goes for the ceiling, you can make a dropped ceiling. Remember, what you are trying to do is slow down the reflections enough so that what you hear is the direct sound without the reflections.
4. Take your mix-down to a friend who has a studio, or actually pay for studio time. A proper mix-down is essential to a proper master. Remember, your master will never be to its fullest potential.
In summary, we have covered having proper monitors, how to set it up in your room, and how to make your room as acoustically friendly as possible. Next month on “SOUND 101” I will review some recording/mix-down techniques that are used to make EDM (Electronic Dance Music).
