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.
It was a collaboration with the company. They probably helped fund it for exclusive licensing to start.
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
I don’t know mate, I wouldn’t replace my electric tools–drills, grinders, saw… with gas ones. But these outdoors tools are a different kind of beast. I’ve only used an electric chainsaw and it was an absolute crap, maybe there are better ones but it was crappier than the smallest and shittiest gas chainsaws I’ve used, and a cord around you in that setting isn’t great either.
The problem with electric gardening tools is they aren’t that feasible for contractors.
Batteries don’t last long and take a long time to charge, so it’s just not an option when you’re working all day. Corded means at every location, you have to figure out outlets, extension cords, fuss with tangles and obstructions, etc.
If you’re doing your own lawns, yeah, you can probably get into a workflow that works for you. But a lot of people hire out for landscaping.
Swappable batteries resolve this issue pretty well. The energy density is far from comparable, but if you’re already hauling a van or trailer to the job site, then a dozen spare batteries isn’t an issue.
Except being very expensive, wear out after a few years (at best), and being sensitive to being in the hot sun all day every day. All in a profession mostly worked by under privileged people where frugality is a necessity of life.

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.
Electric is so much quieter. They have them in Singapore
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.
