Do you hear that? It’s the sweet sound of innovation.   Senior @jhumeche students Michael Chacon, Andrew Palacio, Madison Morrison, and Leen Alfaoury successfully designed a leaf blower that drops the overall noise level by nearly 40%. After workshopping more than 40 versions, they landed on an attachment that cuts the machine’s noise almost like a muffler on a car. @stanleyblackdecker expects this patent-pending product to hit store shelves in two years. Video Description: The video starts with a student using a leaf blower and demonstrating the sound level before and after with the improved product outside on the Homewood campus. It then shows interview clips from four students and scenes of them working in the classroom.
