Alright, I need help from you all, as Google has not helped me in the matter. Perhaps I suck at searching, I don't know. Anyways, I need your help on two things:

1) What, on average, is the distance between the stage and teh nosebleed seats in a theater ? Since theaters vary greatly, I refer to the classic Broadway-esque theaters... the types you see people perform on in the movies.

2) What, on average, is the distance between the playing field and the nosebleed seats in a stadium ? As in sports stadiums, like baseball or American football, or like the Roman Coliseum... if they vary too much, stick with baseball. As the playing field itself is very large, sizes of playing fields in general would help in this matter too... I know from home plate to the outfield walls tend to be 350 feet-ish and from one endfield to another is 100 yards, I think...

Any and all help I could get on the matter would be highly appreciated.

Define nosebleed. You mean the front row?

[Edit: I was close >_>]

Nosebleed = the farthest seats. In sports stadiums, they tend to be called that because they're also the highest off the ground.

If you feel the range in sizes is too great, at least supply the ranges, please. I need SOME idea of measured distances to refer to later for my project in works.

can you not find ground plans anywhere?

Every search I tried came up with where to buy tickets and what they were showing and stuff. Again, I don't claim that my google-searching methods are good, but I did try. As I've said, any and all help I recieve would be much appreciated.

Soccer fields are generally about 100m x 70m. AFL and cricket stadiums are much bigger, being about 170m x 150m.

I've always though 'nose bleeds' to be defined by your height above the playing field. If you're in the top tier (or the very back, if there's only one tier), then you're in the nose bleeds.

Typically, things like that are very stadium specific.

Unless I'm mistaken, what Geb really wants to know is the usual maximum range that the human voice can clearly be heard. Obviously, that's gonna depend on environmental factors to a large extent, but what he's looking for is a base figure to work with.

Unless he's talking about something else entirely...

No, it's the same issue I'm tackling, Krig. I'm working with those two things because voice is not the only thing I'm taking into consideration.

And sorry if the "nosebleed" word choice threw you off -- I really was refering to the farthest distance an audience member would be from a player on stage or on the field.
