How do you mean friend?
I mean it's not just how loud the sound exposure is but how long it goes on.
There are OSHA charts that show maximum exposure and duration. Unfortunately they are designed to only protect the majority of people and not the smaller percentage that us more susceptible to noise trauma. In addition, they are based on the risk of permanent threshold shifts (hearing loss) and not temporary ones, which still result in permanent damage to synapses.
