What sound pollution? There are permits and everything, and woodlands are really, really big. A couple hills over you wouldn't be able to hear a thing.
Perhaps humans wouldn't be able to hear a thing, but what about birds, rodents, and other animals? 100dB is something only humans can produce. To assume that other species aren't negatively affected seems wrong to me. I don't have the data to prove it, however.
Any concert amphitheater probably has 100x the sound power. Our speakers are very loud when you’re dancing next to them, but they’re not strong enough to be ear-splitting to a seated crowd of 80,000 people.
