It is very easy to permanently damage a persons hearing. The young on buses have those dreadful machines so loud that the windows are shaking. A normal conversation between two people is held at about 85db. Constant sound at 90db, for eight hours, will permanently damage a persons hearing. And 90db isn't much!! Damaged hearing doesn't show itself as a loss of the ability to hear. Rather a person with hearing damage is considerably less able to distinguish between background noises, so if there is any other source of noise around, a person with damaged hearing will not be able to hear what is being said to them. A conversation between two people will have to be more or less shouted so the audibly impaired person can hear what's being said to them. Then there's the tinitis, imagine trying to get to sleep on a night with unbearably loud whistling in your ears all night. Fortunately the titnitis clears up, your brain eventually filters it out, along with that whole range of sound; after about twenty years! If you and you're friends are planning doing anything at 265db, make plans to be somewhere else.
Avoid loud noises, hearing damage is a nightmare.

Yes, it would burst your eardrums. But that would be the least of your worries since it would also kill you instantly.

As the sound pressure No's increase logarithmically I would doubt that that figure could be reached, and if it could it would probably destroy whatever was making it.

OSHA says that any level over 85 dB requires ear protection.
