loud bangs

[p robertson]

I hope this is the right place to pose this question. I had recently installed a new amp circuit-board into my case, and switched the power on a loud bang and a white flash! a small piece of metal had shorted the live terminal to the case which was earthed.{btw the house supply tripped}.what I would like to know how loud was this bang in dB any estimates? this sort of thing must have occurred to others.Thanks P.s i'm worried abiut my hearing.

Been there, done that. My hearing still works. The bang may be loud, but it's very short in duration. I doubt it has enough energy to do any damage. But you could always go to an audiologist and have your hearing checked.

Nah, there's sounds loud enough to damage your hearing instantly. 140dB or higher, from memory.

I seem to remember you can never pass 184dB(?) anyway, you can't exceed total vacuum. So that narrows it down already

Thanks for the reply, I sure your right though just me worrying!

Like a 1977 Status Quo concert !
Couldnt hear for 3 days afterwards.
Thats before laws came in to limit concert sound levels.

.30-06 rifle being fired 1 m to shooter's side 7,265 Pa 171 dB (peak)

That explains the very loud seeming breech noise from a .375 H&H rifle that I fired a few times.

Did your ears bleed? If not, try again.

If your ears start bleeding, you may be pointing it the wrong way. I find away from my head best
