Which Generator Won't Hurt My Ears

Hello folks, I am kinda new to these forums and I wanted to ask for your help. I am currently thinking about getting one of these top generators http://generatorist.com/best-5500-watt-portable-generators for my cottage and I was wondering which one would harm my ears the least?

I don't want to buy something that will be bad to my health obviously, but I need something strong to power my living in the wilderness. 

Thanks a lot for any advice, like methods to protect my hearing or which one is the best option.

Have a nice day!
