In absolute silence, 144 dB will cause ear damage. Not probably, will. Or as OSHA says, maximum allowed exposure to 115 dB is about 30 second. For every 3 dBs the permissible exposure time before possible damage can occur is cut in half. 118 dB ~ 15 second 121 dB ~ 7 seconds 123 dB ~ 3.5 seconds 126 dB ~ 1.7 seconds See http://en.wikipedia.org/wiki/Dynamic_range -- Pat Farrell http://www.pfarrell.com/ _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
