I’ve seen some news info about how loud the noise can be from cicada singing. Since Bonne Terre Mo has been considered an epicenter for cicadas I thought I would take some informal readings from our lake house at TDL just outside of Bonne Terre. They are loud but how loud?
Our house is surrounded by trees on three sides and I can physically see cicadas everywhere. I’ve taken three different measurements at loudest times each one about 3 minutes long. The average sound level is Leq= 64dBA. Frequencies range from 1kHZ to 6kHz. Since this includes sounds from other wildlife I compared these measurements to previous measurements without cicadas of Leq=44dBA.
Btw Leq stands for the equivalent average over a time and A stands for A weighted which is how the ear hears sound. ( nerdy acoustic talk)
Yes they are annoying but I don’t think I need hearing protection ( OSHA says 85dBA for 8 hours) to sit outside on the porch. Maybe these cicadas are not having trouble mating lol.
I did see one news report of 80-90dBA measured up in a tree but I don’t plan to spend my day day climbing trees right now.
If they are louder in your location by all means be aware of wearing hearing protection !!!

Reducing noise in our environment continues to be a challenge. I’ve recently had the opportunity to work with customers to reduce noise in the workplace and create more privacy, less stress and a more productive workforce.
