Larry, it's your hearing and your decision, of course, but I'd never listen at that level. If that measurement was a continuous level rather than just a split-second peak, it's well into the area where permanent damage can take place. Examine
this table showing recommended limits from the EPA and World Health Organization on exposure levels(in minutes)for non-occupational environments. The less stringent numbers in the first two lines are for exposure at work, where it's considered(by some)that some long-term loss is acceptable.
My own practice when I'm listening "loud"(more commonly it's about 10dB lower)is to be around 80-85dB average, with a split-second peak on even the recordings with the widest dynamic range hitting no more than about 20dB higher in the 100-105dB area.
