College Students Invent Quieter, Powerful Leaf Blower

Quieter Mornings Ahead: College Students Invent a Leaf Blower That’s 40% Quieter and Just as PowerfulPhoto byWILL KIRK / JOHNS HOPKINS UNIVERSITY

BALTIMORE, Md. — Wake up on a Saturday morning to your neighbor's leaf blower? Relief is on the way! A group of engineering students at Johns Hopkins University has developed a groundbreaking leaf blower that’s nearly 40% quieter while retaining the power and functionality users expect.

This innovative device is the result of an ambitious project where students meticulously analyzed the complex sounds produced by traditional leaf blowers. They focused on mitigating the most irritating aspects of the noise, ultimately designing an attachment that functions like a car muffler. This attachment effectively reduces noise without compromising the blower’s airflow and power.

“The noise is deeper,” team member Leen Alfaoury explained in a demonstration video. “It is not screechy. There’s no high pitch sound that is, like, really annoying to hear.”

The invention, now patent-pending, has garnered significant attention. Stanley Black & Decker plans to manufacture and distribute the product within two years, potentially bringing quieter mornings to neighborhoods nationwide.
