Question: How long can a person endure a certain noise level before hearing impairment occurs?
"Permissible 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
82 dB = 16 hours
Lower dBs are said to be harmless

Accepted standards for recommended permissible exposure time for continuous time
weighted average noise, according to NIOSH (National Institute for Occupational
Safety and Health) and CDC (Centers for Disease Control and Prevention).
For every 3 dB sound pressure level (SPL) over 85 dB, the permissible
exposure time is cut in half - before damage to our hearing can occur.
