I visited Oz twenty-summat years ago and, while there, we went to a zoo somewhere North of Melbourne. A kookaburra was perched near the exit of the aviary and I was maybe six feet away from it when it went off. By Dog, it was bloody loud. You seriously wouldn’t believe how much noise can come out of such a small package.
What amazes me, here in the Midwest, is how loud the cicadas are. Per some website,
According to the U.S. Centers for Disease Control and Prevention (CDC), exposure to sounds of cicada buzzing, which can reach 100 decibels, for 15 minutes can be enough to cause noise-related hearing loss. The CDC says 100 decibels is approximately the noise level of a motorcycle revving or a jackhammer in operation.
Imagine a tree full of them! [Such as the linden in our front yard] I don’t understand how something so small can be so loud — it has only a tiny surface area to induce vibrations in the air, right?
Cicadas – we have to filter out the frequency of cicada noise in some locations at certain times of year because otherwise it’s impossible to make noise measurements. Adds a level of error sadly. CDC is correct. That’s your noise dose for the day right there in 15 minutes. if that’s all the sound you’re exposed to – no biggie. if you got hours of that daily for a month or so a year, it would have an impact.
Kookaburras – impressive, but oh so Australian ;-)
Crickets can be loud, too. And when I was living in Oklahoma City, we had a summer filled with millions of grackles in the city. My, those grackles are loud! Especially when there are hundreds of them right outside your bedroom window early Sunday morning.

Some animals have amplifiers built in. Siamangs and gibbons for instance – hot DAMN they’re loud for their size.

Then, there is the mating call of our furry friend, the Koala. Sleep is hard at night when a whole colony is on the mate!
