While I don't know that I've ever experienced a double brood, I've experienced plenty of cicada hatches in my life and this is probably the best way to describe the auditory experience that I've seen! I never know how to describe it to people who haven't been in it but that's a great way. It feels like you're almost swimming in the sound it's so intense. I once was driving along a highway during a brood and thought something was wrong with my car because of this awful sound that had just started, stopped at a rest stop, and was instantly immersed in cicada sound. It was wild!
