A quieter leaf blower? No. They did not do that. They found a way to quiet an existing leaf blower. Adding a silencer to a gun doesn't mean that you have invented a new gun. >> They workshopped more than 40 versions of the solution they finally settled on: an attachment that cuts the machine's noise almost like a silencer on a gun or a muffler on a car.

This device looks like it could be used on any leaf blower, although the difference is probably less dramatic on a gas-powered model.
