Honestly I expect to see a Dyson Leaf Blower.

Re: Students invent quieter leaf blower
#12Minor nitpick about the reporting: > The team reduced the overall leaf blower noise by about two decibels, making the machine sound 37% quieter. While a 2 dB reduction in noise does represent a 37% reduction in acoustic power, our perception of sound is logarithmic so this is extremely unlikely to "sound 37% quieter"-- Assuming the reduction is from 50 dB to 48 dB, it will sound about 4% quieter. Much more significan…
In the video, we see the students briefly rotating the model in the CAD software—with translucency on—it looks like the one main stream is divided into many spiral chambers which then exit distributed along the rim of the attachment's opposite side.
With that in mind, I wonder how much, if at all, the reduction would be if the entire nozzle were designed this way, instead of just the end bit.

#13First, it's an attachment that could fit on nearly all blowers. Second, it dampens the noise while retaining all the force. If this works out, it will be amazing! Kudos to the student teams!
Looking forward to being put on a list for purchasing a leaf blower silencer.
Not to mention the 3D print files.

#14I didn't know of electric-battery-powered leaf blowers! Here in France i always suffer gas engine blowers which are so annoyingly loud and smelly.
Re: Students invent quieter leaf blower
#15Is leaf blowing a worldwide nuisance or an American thing? I hate it. And it serves no ecological purpose.
Worldwide.
Sucks to be an earthling trapped here with leaf blower jerks.

I'm in Australia and someone near me has an electric one.
Although quieter than the gas ones, it's still far from silent and the noise is still annoying but higher pitch. Like a high-pitched vacuum cleaner noise.
Most people have the much louder gas ones though, they're the worst, and anecdotally the people operating the gas ones seem to rev them up and down more which makes it even more annoying.
Every time I hear one, I have nothing but negative thoughts about the person using them, and disgust for the society that allows them to ruin the environment for such minimal benefit.
A rake works almost silently... but then you can't irritate everyone within a kilometer radius.

#17After reading all comments, not rushing to the comments, I have to say, I have a quiet leaf blower to, it is, as mentioned in this thread somewhere else, a rake and I would appreciate if more people would use one.
Re: Students invent quieter leaf blower
#18Patented and licensed, so not coming to a neighborhood near you unless mandated by local government. Because while people want their neighbors to use it, in enough cases they won't pay the extra and rationalize it somehow.
You wouldn't download a quieter leaf-blower... unless of course you had a 3D printer
ATF: you got a tax stamp for that suppressor?
Re: Students invent quieter leaf blower
#19Congrats to these students for producing a clever solution to a real practical problem! I hope that the students will own the patent, and not the university. Many schools have a way of taking ownership of absolutely anything their students come up with.
That said, I prefer just raking up leaves manually. It makes no noise, it's quiet, and it's good exercise.

I agree completely!
My favorite weed killer is my own two hands and a weeder.
Having said that, I live in Arizona and the dominant landscape design here is trees and bushes planted with rocks for the ground cover. A leaf rake is real good at picking up both the leaves and the rocks. I wish there was a leaf rake that didn't pick up the rocks. I have grudgingly bought an electric leaf blower because of the rocks :-(
