Leaf-blowers

Is there a reason why leaf-blowers have to be so unbelievably freaking loud?



I understand their function, and how helpful they can be when it comes to gardening and yard work...but why is it that one simple leaf-blower is capable of producing the same amount of noise as a small bulldozer?

Imagine that you're sitting in your home office (okay, fine, your bed) trying to get work done, but you can't, because it's lawn maintenance day on your block, and for two and a half consecutive hours, the only thing you hear is the constant blaring buzz of leaves scattering about. Of course, the noisier it is outside, the more my dog is likely to react inside, causing excessive high-pitched barking right in my ear on top of the ever so pleasant leaf-blowing backdrop.

It's a wonder I ever get anything done.
