You bring back memories of Gladys Kravitz from Bewitched! You weren’t just imagining things. I spoke to Linda Gedemer, an acoustician at Acentech, who reminded me how far thunder can travel. The distance that sound waves roam, she says, depends on terrain, tonal frequency (if their pitch is high or low), weather, and wind. Bass notes on a warm, breezy night go the farthest. The Electric Daisy Carnival was held at the Coliseum this summer, on a day when it was 78 degrees and the wind was gusting. Those ravers do love their loud beats.
