After the overnight heavy rains and storms, they've gotten even louder. Noise started about 3 days ago so probably another 2 or 3 weeks to go. My driveway has quite a few dead ones.
Just checked the noise level using my iPhone app: 40dB inside my garage with no other noise sources, 71 dB just outside the garage door. Of course, that includes other background noises as well as cicadas but I have no idea at the moment what the usual background level would be. I'll check after the cicada invasion is over.
