Nice to see proof that, while still quite loud to the user, multiple tested battery blowers fall off to reasonable levels by the time you get to 100-200ft which is a pretty typical distance for neighbors in a lot of areas.

Key takeaway regarding gas blowers: "Noticeably louder to 4 times louder"

Thanks for the link, that’s good info. My model is listed; it seems accurate from experience: way too loud for comfort while operating it, would be disruptive to a bbq 50 feet away.

The gas ones are certainly louder, though.
