The sound pressure or its level can be harmful if it is moving too much your eardrums.
"Permitted Exposure Time Guidelines - SPL"
Sound pressure level Lp and permissible exposure time t:
115 dB = 0.46875 minutes (~30 sec)
112 dB = 0.9375 minutes (~1 min)
109 dB = 1.875 minutes (< 2 min)
106 dB = 3.75 minutes (< 4 min)
103 dB = 7.5 minutes
100 dB = 15 minutes
97 dB = 30 minutes
94 dB = 1 hour
91 dB = 2 hours
88 dB = 4 hours
85 dB = 8 hours
