http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_438_438 Anyone ever actually hear this thing on? It says "Oversized muffler with spark arrestor screen produces only 67 dB(a) @ 7m". I know that the 5000W ones are stupid loud. Let me know. I dont want to be that guy.... Yes, I know Hondas are really nifty and quiet.
Well, if this puts it in perspective for you - 67dB is in the same range as a vacuum cleaner (about 50-75dB). Now, you will need to be ~23 feet away from it (with nothing like a trailer or building to echo the noise) for it to be as loud as a vacuum cleaner. Standing right next to it will be considerably louder. Stickboy274 sells a very similar generator that isn't quite that loud. You can have a conversation with someone standing right next to it. Its not Honda quiet, but it will get the job done. Hope this helps.
