Okay, so is this dangerous or not? From what I've read if this happens one should remember what caused it and avoid repeating it.
Well, I have mild temporary threshold shift with small bit of ache in my right ear. This occurred after listening to my sub trying to play the loudest scene in the movie Inception (elevator/mountain facility explosions) - you see we are having some friends over to watch it this weekend and I wanted to make sure the VTF-15H can handle at the desired level and setting.
At the listening position I was getting peaks of 103dBC (109dBZ). But I did spend some time closer to the sub while listening for distortion, port noise, or bottoming out (about 3-4 feet and closer to the wall). I was having peaks up to and perhaps above 110dBC in that location. I had the DIY mic about 2 feet from the sub and it was maxing out (it was calibrated with REW to only go 113.5dBC) I had the movie at -10dBFS. Most dialog was around 65dB.
The overall SPL of the scene was averaging around 85dBC Slow at the listening location. But I repeated the scene over and over while taking measurements and adjusting some settings on the sub. I did this for perhaps an hour or so, with maybe 10-15 minutes near close to the sub.
So I'm writing this to ask at what SPL, and for how long, does it take to have TTS? And more importantly how dangerous is it? I realize there are various degrees of TTS, but still I'm curious if any of it is safe.
