Ayone know the wattage used at a Rock concert?

I thought the world record was 134 decibels by Motorhead.

I don't doubt that there are bands that are playing louder than the Who did way back when, but whether or not they make it into Guiness is another story. I also have to question how the spl measurements were taken, the distance from the stage, the size of the venue involved and the amount of bodies in attendance. All of these things will drastically alter the results of any type of measurement. Sean

Well, I never heard the Who in an indoor venue, but for my money, the loudest I ever heard (made me leave, the only time that ever happened) was Mahavishnu Orchestra ca. 1971 in CT. My ears hurt even now, thinking about it (and my brain cries out, "why o why did you stay for even 10 minutes?"

The Who's summer tour had 120,00 watts of audio power.

Well i heard some loud concerts in my day. But in 95 i was working for pro audio and i was a record holder for that year a us auto sound compition in kansas city. Our van produced 191 dbs which was a record you could her it a 2 1/2 miles away. That was 22000 watts. But as for concerts. ive worked as a sound tech and on average 30,000 or more depends on what kind of music. Ive worked with groups like Alabama and the use 40,000 watts but look at pantera who used 25,000 watts, but you have to mention a group like scorpions 60,000 watts but remember we are talking about bands that could rock 20,000 crazy fans and still could be louder. A b1 bomber her tubines can produce well over 250 dbs at half throtle witch could damage or even kill.so sound all you have to remember that 1000 watts with no obstuctions can carry to the horizon
