Re: P.S.

"Despite what I've read others post here, the SPL of a 100 piece symphony orchestra playing at full volume (fff) rarely goes over 100 db in the audience."

I have to disagree with this.... I've heard quite a few unamplified orchestral performances where I thought the peak SPLs approached 110 dB. Note that these are instantaneous- Such as a combination bass drum thwack and cymbal crash.... The levels were not sustained long enough to do major damage to one's hearing.

Also note that a distorted signal will seem louder than a clean signal at comparable SPLs. And because of that, a symphony orchestra rarely sounds "loud", but the acoustic energy that's present is of a higher SPL level than one would think.
