As far as the law is concerned:

http://www.hse.gov.uk/noise/regulations.htm

Quote:
The level at which employers must provide hearing protection and hearing protection zones is now 85 decibels (daily or weekly average exposure)


From the the U.S. Occupational Safety and Health Administration:

http://www.osha.gov/pls/oshaweb/owadisp ... &p_id=9735

Code:
         TABLE G-16 - PERMISSIBLE NOISE EXPOSURES (1)
______________________________________________________________
                            |
  Duration per day, hours   | Sound level dBA slow response
____________________________|_________________________________
                            |
8...........................|                    90
6...........................|                    92
4...........................|                    95
3...........................|                    97
2...........................|                   100
1 1/2 ......................|                   102
1...........................|                   105
1/2 ........................|                   110
1/4  or less................|                   115
____________________________|________________________________
 Footnote(1) When the daily noise exposure is composed of two or
more periods of noise exposure of different levels, their combined
effect should be considered, rather than the individual effect of
each. If the sum of the following fractions: C(1)/T(1) + C(2)/T(2)
C(n)/T(n) exceeds unity, then, the mixed exposure should be
considered to exceed the limit value. Cn indicates the total time of
exposure at a specified noise level, and Tn indicates the total time
of exposure permitted at that level. Exposure to impulsive or impact
noise should not exceed 140 dB peak sound pressure level.



Any exposure to more than this would result in permanent hearing damage. We can keep this in mind and eventually monitor the sound level of our shows to ensure a safe environment for our staff and volunteers.

Nope. This just came up in the workgroup meeting.
