Electric leaf blowers are already far quieter than their gas-powered peers, but they still aren’t the kind of thing you’d like to hear first-thing on a Saturday morning. Looking to impr…

    what they did :

    “Our product takes in a full blow of air and separates it,” said team member Leen Alfaoury. “Some of that air comes out as it is, and part of it comes out shifted. The combination of these two sections of the air makes the blower less noisy.”

    … “It ultimately dampens the sound as it leaves, but it keeps all that force, which is the beauty of it.”

    Their design cuts the most shrill and annoying frequencies by about 12 decibels, which all but removes them, making them 94% quieter.

      This “conversion” from decibel to per cent is more than ridiculous.

        Why? dB is logarithmic so it’s difficult for people to picture how loud something is, if that’s the only number given.

    If it were me that designed this, I would license out the design for manufacturers to use in their production models instead of making some kind of attachment that is unlikely to work on all models. That seems much more likely to achieve the goal of reducing noise from leaf blowers long term. Get like 3 manufacturers on board that could even charge a premium, and you have reduced the noise potentially forever while still making a tidy profit.

    MAKE GAS LANDSCAPING TOOLS ILLEGAL

    Give away free electric tools if they trade in their gas ones. It’s so bad for health to be huffing 2 stroke fumes all day every day.

    Edit, I realize that this is meant for a electric leaf blower since it would do fuck all for a gas one. Doesn’t change my opinion about landscaping tools tho

      The gardener in my last apartment replaced all of his powertools (mower, blower, trimmer, …) with electric ones powered by an accu-pack he carries on his back. This is an absolute game-changer! I could actually sit outside again and even do stuff for work, when he was there.
