What is the Golden Mean, a.k.a. the Golden Ratio, a.k.a. a ratio of 0.618? It’s a mathematical relationship discovered by the Greeks that occurs widely in nature and is also used for various things, such as finding the optimum room dimensions for the best acoustic results. But here’s another application for you to try: use the Golden Mean to calculate your listening position in your studio. Place your listening position at a distance from the back wall equal to the Golden Ratio times the length of the room.
So, if your room is 20 feet long, place the listening position at 12.36 feet (0.618 x 20) from the back wall, then create an equilateral triangle with your monitors based the listening position.
Note that this technique works best in a rectangular room; as the room’s dimensions approach a square, it will be less effective.
