I dont think audiologists have a clue. All we know is for sure that super loud prolonged exposure is bad - gunshots, cannon etc can cause instant damage. Rock concerts are damaging. Another big factor is aging - hearing (like eye sight) deteriorates with age - some much faster than others.
I agree that giving ears a break is crucial. Avoiding loud rock concerts. Also avoiding instantaneous damage from loud explosions is key. It appears that continuous background noise is also bad (engine noise in a mechanical room or factory).
I suspect ear buds are very bad as low frequencies are trapped in the ear between the bud and ear.
Natural variability in the individual makes it so hard to generalize.
