Helix can do about 120dB.....Helix baby. Lotsa EAW. JBL, SLS do well over 130dB SLS can handle lotsa kilo watts, incredible stuff......music is meant to be absord felt and heard, if ya just wanna hear it, get a clock radio. 180dB must be incredible.
I have a feeling that 180db would cause your ears to pop and probably cause irreversible damage to your hearing.
180dB might even rupture internal organs....hearing damage occurs a lot less than 106dB for some extended period. 180dB is properly weapons grade sound levels.....
And guess what? It is coming back...
Anak Krakatoa is the site of the original explosion and left open ocean in its place. In 1927 it started coming back. The Krakatoa island is what is left of the original island after the explosion.
In 1975/76? my ex and i attended the Emerson Lake and Palmer "Brain Salad Surgery" concert at the smallish Anaheim Convention Center. They ran quadrophonic 10K watt P.A.'s and huge amp stacks. She said "It was like having a wire pulled through your brain". It f***ed up our hearing pretty bad. Featured Keith Emerson and his famous grand piano rotisserie spinning like a top.
I can remember my best friend's brother went to go see Grand Funk one time by himself. When he got there he saw on the stage basically just a small drum set and some guitars. But those amps just blew him away. He couldn't hear right for a few days after that. Same thing happened to me at the Cheap Trick concert I mentioned above. My ears were still ringing the next day. I had to have damaged my hearing. No doubt about it. I went and saw Santana at the outdoor concert arena in Albuquerque a few years ago or so. They were just right. About 80 decibels at a couple of hundred feet. I have one of those radio shack meters so I'm just guessing based on reading the meter while listening at home.
Yea, the little Radio Shack meter is handy... Concerts in the '70's were just brutal. Grand Funk had a rep for being the loudest. ELP stacked their quad p.a. towers IN the seating areas. I saw J Geils and Johnny and Edgar Winter and White Trash at the Santa Monica Civic ('73/'74) and we had to move away from the stage and sit way back. TOO LOUD TO ENJOY!! Our ears would buzz for a week. Who knew ?? Groups like Traffic, Zappa and the Mothers and CSN&Y really dialed in their sound to suit the venue. Elvis Costello and the Attractions (This Year's Model- his angriest and rockingest tour) in '76 came on stage with the barest minimum of equipment. The drummer had a simple 3 piece trap set. We thought they were going to suck and they flat rocked the house. Everything was perfectly miked and the only amps you could see were the stage monitors. They gave us goose bumps. Mink De Ville and Stray Cats opened. Tickets were $7.50. What a concert.
