I couldn't remember the exact numbers, but I thought it was around 80db. According to OSHA, it's a little higher, at 85db they suggest ear plugs:d)(1) When information indicates that any employee's exposure may equal or exceed an 8-hour time-weighted average of 85 decibels, the employer shall develop and implement a monitoring program.
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................| 115What you have to realize is that these are the levels and durations where damage is guaranteed. According to OSHA, you're ok for an hour at 95db. But listening that loud begs for more volume and you'd have to go to 100-105 to sense much increase and the safe time limits get increasingly small.
I don't know about woofers. Over execusion is typically a problem AFAIK.
