In my opinion, loud starts at a rock concert under normal circumstances at around 105-110 db. Please tell me what you think! Am I noiseboy?

dbA or dbC? There can be a big difference in perceived loudness between 110dbA and 110dbC.

Shame on me, shame! I can't remember!

The one that is corrected to human perception...

loud is when it is in excess of the situation. 95 Db is a roar to an audience that is quiet, and yet talking to each other during the performance. At the same time, loud can be 120 at a metal gig, and the crowd starts moving back from the "steal your face ripping mains", or it could be from proximity of a 2,000 lb compisition "B" munition compressing your body with low frequency waves well over 120.

Watch the audience, they will let you know if they start having a problem with loud. Other than that, it is your choice as to what fits the situation.

good luck,

Mark

I always spec systems to be capable of producing a clean 110dB at the mix position, with adequate coverage for the entire venue, and this seems to work. Our local authority insists that 95dB is plenty loud enough and doesn't like people making more noise. No one i've met takes any notice of this. It depends on what you are doing, and how much ambient noise there is.

It all depends upon the situation. On stage my band runs on the loud side for bigger stages at 96dB and a FOH at 105dB. For small clubs we turn down to 91dB on stage and 98dB for FOH.

This seem to be a comfortable for our situations. We always use a dB meter for all of our shows. It works for us. Every situation is different. Indoor to Outdoor and everything in between. Posted by Marty McCann on May 15, 2002

Loud is in the ear of the "Behearer".

Guns & Roses may not be too loud for a teenager at 90 dB. But,his truck driver father may insist that he "turn it down". However if the kid played Merle Haggard, at say 85 dB, dad would probably tell him to "turn it up".

Of course a distorted sound is perceived as louder than an undistorted sound at the same level.

When making measurements regarding OSHA hearing regulations the dBA scale is the only one to use.

The loudest show that I heard recently was a Jars of Clay concert in a Metal building (Agri-Center), it measured 115 dBA at the top of the bleachers. Positively deafening.

The loudest thing I ever heard was an explosion of an underground ammo supply bunker in Vietnam. The blast was so strong it knocked over an outdoor Shit House (unfortunately, I was in it at the time).mfm

Could that be what is called a "shitload of loudness"?

Just Kidding!
