Golden Ratio

[I'm Painting Again]

somehow special or magical have the same credibility as fortune cookie fortunes

I love fortune cookies!

to help everyone remember the Golden ratio

1.6 is the lonliest number

thank you

rather 1.618033988749894848204596834365638117720..... is the lonliest number hehe

gotta love those nerds!

In case anyone's interested, the "golden ratio" is that ratio which is created when you cut a straight line into two sections, A and B, such that the length of the whole line is to the length of A in the same ratio as is the length of A to the length of B. So for example, 1.6 is to 1 approximately as 1 is to .6.

Given this ratio's peculiar construction, it is reasonable to suppose that it might be "found" in nature more than any random ratio.

As to whether it is a magic number for the construction of room ratios, let me ask you this: do 6, 10, and 16 share any common factors? Sure they do, so this room will have bass problems, eh?

I haven't check my memory versus facts, but I seem to remember that the Golden Ratio is used to figure out string vibration harmonics somehow. So it would seem to me that using the same ratio to set up a room could result in a room that would encourage harmonic build-up & standing wave problems. But like I said, i haven't checked my memory versus facts.

And the gregorian chant remark, I think the cathedrals weren't built w/ sound in mind, but the chants were written to accomodate the long reverbration times. I think.

not sure if this helped answer any questions....

The important ratios in string vibration are all simple ratios - 1/2,1/3,1/4, etc of the string length. This is because a string can vibrate with stationary points at equal intervals along the string, creating 2, 3, 4, etc equal segments of the string. In fact, all tonally pleasing vibrations possess the same characteristics (air columns, strings, well I can't think of anything else that can be reduced to one of these), because, essentially, the brain enjoys moderately difficult but not impossible tasks, and resolving combinations of simple ratios into their component parts is just right.

To sum up, I don't think the Golden Ratio is useful there.
