Students’ Leaf Blower Suppressor To Hit Retail

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.

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

Electric is so much quieter. They have them in Singapore

I still say replace them with rakes.

seems like snake oil. whe using my electric leaf blower all the noise sounds to be coming from the big fan at the top of the device and not the nozzle

Why do leaf blowers exist in the first place?

So it's taking some of the air out of the stream, slowing it down, and putting it back in the stream... How does this not affect the performance?

Companies know they can make tools quieter. They didn't do it because louder sounds more powerful to consumers.

Why not just use a rake and a broom?

Somebody tell Kate Blanchett

I want the stl!

Let me help you with the correct wording: 'Power to noise'-converters. You're welcome.

Why isn't there video of this yet? I didn't care at all what an article says. Show me the video

I'll wait until I can 3d print my own. I'm not paying for a hunk of plastic.

Good. I fucking hate leaf blowers.

The best invention against leaf blowers so far is the scrapyard.

There’s no way this won’t affect the final CFM or Velocity of the air.

This would be no different than running it at a little less than 100% power, but wastes that energy instead.

Why else would they not provide any technical detail, even a wind velocity test would be huge FFS.

Are the majority of people who use leaf blowers regularly really going to buy/use these?! I think the leaf blower droning is almost a relaxing noise to me but those god forsaken commercial mowers are a little annoying
