Give then a Nobel Prize!
It’s almost like it’s a requirement for every landscaping company to use the most noisy, ear destroying, gas-powered leaf blower that they can buy that can be heard from 2 city blocks over.
Probably. lol. You look out the window to see what’s making all that racket, and you see their logo on their truck / shirts.
Gas powered is still vastly superior for things like leafblowers. A good gas one can last 15 years and take a total of $40 in maintenance parts for that entire time, all while blowing harder. High end battery powered ones will last 45 minutes and need a couple hundred dollars worth of replacement batteries every few years. My stihl from 1997 still works like it’s new.
For 99% of applications, a corded electric blower with an extension cord is far superior than every other option.
Sure, if you need less power and want to deal with the extension cord, and where you’re blowing is within 100 feet of an outlet. Doesn’t work well for gutters or large properties or houses with only 1 or 2 outlets outside.
Huh. I can’t think of 297 other uses for a leaf blower, so I guess your 99% claim might be a bit…overblown.
How high are your fucking gutters?
Just one nitpick – usually one can swap out batteries and continue to use the tool.
30 minutes from a $100 battery vs an hour from a $1.25 in fuel, no recharging, and no batteries that go bad.
Especially gas-powered as they can then rev them all the time, raising the annoyance to completely new levels.
Too bad no one invented rakes yet.
This is like comparing sweeping to a proper vacuum cleaner
Kinda, although recent vacuum cleaners are way less noisier than gas-powered leaf-blowers.
Well now I want a gas-powered vacuum
You ever tied using a metal rack on pavement? It’s about as pleasant as nails on a chalkboard.
Jackhammers are so loud, haven’t they heard of a hammer yet? I am very smart btw.
Jackhammer and a hammer are not doing the same job. Pickaxe is more akin to a jackhammer.
Okay
Jackhammers are so loud, haven’t they heard of a pickaxe yet? I am very smart btw.
This does nothing to address the lovely whirl of a 2 stroke.
Electric leafblowers exist. That problem is already solved.
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.”
Adds Chacon: “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.
I wonder if that shares the same physics as silvent’s compressed air guns.
Silvent’s air nozzles reduce the sound level when blowing with compressed air compared to blowing through open pipes. This is due in part to the reduction in noisy turbulence from using Silvent’s air nozzles, and also because of the nozzles’ special design. Silvent’s air nozzles pass the compressed air through small holes and slots, which raises the sound to frequencies beyond what the human ear can perceive. This allows us to make blowing with compressed air both quiet and efficient.
Could use an even quieter compressed air gun
No, not the same … in your paragraph you describe an increase of the frequency at a level human hearing do not perceive while the other made cancellation of a given frequency using phase shifting and recombination.
wtf is shifting?
The wording is comically awkward and imprecise. But if I had to guess, they figured out a way to fiddle with how the air is routed through the secondary portion such that the emitted noise is phase-shifted to cancel out the frequencies they’re targeting.
Seems baffling
Eeeeeeeeeeyyyyyy
Cue right wingers protesting the new “woke” leaf blowers.
Cue the left-wingers being rage-baited about the right wingers protesting the new “woke” leaf blowers.
All the while the leaf blower manufacturer is getting free publicity.

Coming soon: The all new, all American, COAL powered leaf blower.
Now with a slide whistle and megaphone attachments for extra annoying noises.
Whistle goes, “Woo, woo,” but that’s only in the mo’ning.

pasta powered leaf blower
I’ll let my gas powered leaf blower running all day now to make your woke blower useless. Get owned, sucker
Blowing coal lel
There certainly are plenty of people who use those things because they enjoy being obnoxious twats.
I use things that work (even if you find them loud or annoying) because typically over engineered things (like the ‘quiet’ leafblower) are most likely very problematic and will fail. I just do not trust anything new anymore. Companies did this and forced me to stop caring about ‘innovation’ with their constant lies and fraud.
Edit downvotes clearly from people who are pissed they have to replace their expensive appliances every 5-7 years because ‘innovation’
I use things that work
Blowing leaves around instead of removing it, isn’t ideal then.
Leafblowers are used to collect it into a pile which is then raked/shoveled into a bin. The blower is much faster and less effort than the rake at collecting everything into the pile.
Everyone I see using them merely uses it to blow the detritus into the street. What you’re saying makes a lot of sense, but people don’t do that
Yeah, well, you can’t fix stupid.
Although if there isn’t that much, I suppose letting it dry and break down in the local environment is better than putting it in a landfill. If there’s a lot of it, then at least in cities I’ve lived in, they can and do ticket for putting yard waste or shoveling snow in the street.
No, that’s what a rake does.
Yeah, I figure that’s the kind of thing they’re going to say.
No we obviously need more cheap plastics that will dry rot in your shed and shitty rubber grips that will turn to sticky goo in five years, as well as lowest bidder designed control circuitry with a dozen corners cut.
I get what you mean, modern power tools feel like Fisher Price toys. They’re disposable.
What happened to the giant metal vacuum cleaners that doubled as a blunt-force weapons?
Hey, don’t diss Fisher Price toys. The old ones from 40+ years ago were solid. So much so that the iconic telephone on wheels and with eyes is still around.
Modern day crap though? Oh I’m with you!
Maybe the garbage brands. Milwaukee, DeWalt, Makita, etc are very well made, and significantly more powerful than they were 5-10 years ago.
This is very true. I just know my neighbour wouldn’t choose a quieter option if he had the chance
Seeing how some very particular relatives are, I wonder if much of the gas leaf blower cloud is less “watch me stick it to the libs” and more “look at me, I’m cleaning my yard, that makes me better than you”
And by “cleaning my yard” they really mean “blowing whatever I consider a mess onto whatever is beside my yard, or in the general vicinity for the dust”.
The same kind of morons rolling coal and destroying their engines.
I instantly imagined someone rolling coal with their leaf blower… you know it’s going to happen, even if they’re not diesel.
No, they’ve moved on to “DEI” as their racist dogwhistle now. Keep up.
“I’d never even heard of this 2 weeks ago, but after watching a single 90-second segment on Fox News, it’s all I can talk about and clearly the reason why the country is failing!”
Too bad these innovations wont make it down to the workers that stores hire from 11pm to 3am to clean the store parking lot across from me.
Good thing is you could 3d print some and give them to them. If they use a compatible blower that is. Or if you’re handy with modeling you could probably modify the attachment part.
(10 hours of work later)
“Ok how much money will this save me for the risk of your plastic thing melting all over my blower.”
I invented a leaf blower that is 100% silent and is shaped like a rake.
Interesting, my rake makes some sounds when I use it. It’s pretty loud on hard surfaces.
Let me just rake up all this sand and grass clippings.
Too bad there isn’t one shaped like a broom.
I think we’re on to something here. Like, different takes for different things to rake up. Brilliant!
That’s way too expensive. I just use my fingers.
Can I borrow them to clean my yard? I promise I’ll get them right back to you.
“Patent pending” and already picked up by a major manufacturer. So what this means is basically while it could be a good thing… the article is basically an advertisement for an upcoming product.
Not nearly as good a thing until it gets copied/the patent gets worked around. Also, zero explanation of what was actually done to accomplish this, so again, leaning more towards “this is just advertisement with extra steps”.
Good engineering and industrial design programs find opportunities for students to work with real companies on real products.
Back in the day I used to be the student that published stuff like this to our product design department’s website. The point wasn’t to demo tech or sell a product, it was to make the program look like something worth applying to and donating to.
If a brand was name dropped, it wasn’t because we wanted to sell their thing. It was because we wanted to let applicants and alumni know that we were offering real world experience with recognizable companies. It’s basically like a reverse internship. Department faculty finds companies to bring to the students, as opposed to students applying to companies.
Man. People will be negative about everything.
New breakthrough that may change the entire landscape of an industry? Oh, we hear about breakthroughs every few weeks. Call me if it actually makes it to market.
New apparently game changing breakthrough that’s already being taken to market? Boo advertising, we should just quiet launch it and see if anyone notices? Seriously?
IMHO, the thing that’s being promoted here isn’t the leaf blower. It’s the university’s engineering program and the opportunities it’s providing for students.
I kind of doubt someone has this University blog post in their deck of Spring 2024 leaf blower marketing initiatives.
This is the kind of stuff that the people managing internships handle in a company. Companies do this for talent acquisition. They don’t even do it for the cheap labor, because coaching students usually gobbles up a lot of your IC’s time.
Now do the trimmers and the lawnmowers
What about hair dryers?
Do them too!
It been brought by Black & Decker, no ?
It looks like it was sponsored by black and decker but the whole article looks like an ad for Dewalt…
Black and Decker owns DeWalt.
Cool, do they offer whistle tips?
It’s that woo-woooooo
Yes its called not gas powered.
This is about making an electric leaf blower even quieter. The students were not given a gas leaf blower to design around.
How could you possibly know this!?
A spirt visited me and told me this.
Luckily that spirt read the article and watched the video in it.
Why not use a rake? It exercises you and doesn’t pollute. Plus it can make you laugh if you see someone walk into it and gets slapped cartoon style in the face.
Neighbor’s tree dumps leaves all over my concrete patio, every week. Rake doesn’t work well on concrete, doesn’t fit in every crevice the leaves fall in around my yard, and also takes awhile. Leaf blower does the job in 5 minutes. If you’re faced with this problem, you’ll pick the leaf blower over using an awkward rake for 20 minutes every week.
Also, leaf blowers are now battery powered, so concerns about gasoline emissions are not as much of a factor.
Battery-powered silent leaf blowers. We really are in the future.
Can’t wait to use this in Leaf Blower Revolution
