…is this not just a muffler/silencer for leaf blowers? Good on these kids! This definitely falls under the ‘why didn’t I think of that!’ category for me.
correct me if im wrong here, but gas leaf blowers are inherently many times louder than electric leaf blowers to begin with. Calculating the near field DB levels doesn’t really count here since most of the annoyance is actually going to be from other people who have to listen to it running.
And since electric leaf blowers often have a much higher pitch, that pitch attenuates at a much greater rate, especially compared to that of an ICE meaning that it’s often silent, if not very quiet, at the same distance that an ICE would be rather loud at.
Also, in my defense 90% of articles these days are not worth reading, i’m sure they probably did something as i literally mentioned in my previous comment, but like i said, comparing this to a traditional ICE leaf blower (which people seem to fucking love for some reason) in comparison i’m still pretty confident that this would make almost zero fucking difference, since the vast majority of noise coming from an ICE blower is not air noise, but engine noise.
But yes thank you for telling me that i’m wrong and bad for not reading an article about an item that has probably 20-30% market share from my anecdotal experience.
i am aptly aware of this, in fact i’m aware of the fact that it’s actually a 12db drop in volume. Someone else kindly told me what was in the article.
But my primary point is still true.
and in defense of myself, most articles are bullshit anyway. 50% of it is filler, and 20% of it is useless information, edu sites are generally better, but there’s no guarantee, and i don’t bother with most articles these days. And my problem here isn’t even the fact that they did drop the volume of the noise, my problem is that i’m not sure this is a significant accomplishment.
There are a lot of fields actively researching this exact same concept.
i’m not here to read articles most of the time, because people talk about what’s in the article here. And in this case, leaf blowers, specifically electric ones are a bit quieter in near field operations.
Which i definitely expected, based off of the headline, but like i said, compared to a traditional ICE leaf blower, especially commercial backpack setups. Does it make a difference? Uhm. Not sure.
It’s funny to me that people yell at me about not reading articles, even though i understand the general pretense of it, without reading it. People literally corrected me by stating numbers, because that was the only thing i didn’t mention, since i didn’t read the article. And i didn’t even come here to speak about it, i mostly came here to complain about the fact that small ICE engines exist on lawn equipment.
I’m completely uneducated in this field, but there’s a 2 min video attached to that page that demonstrates before and after. Sure sounded better to me ¯\_(ツ)_/¯
i’m not educated in the field specifically, but what i do have a knowledge base of is the fact that this probably isn’t a technical W for the leaf blower industry, especially judging that most commercial leaf blowers are gas ICE based equipment, and that even with the home market being more accessible than ever, a lot of home owners still use ICE based equipment.
Put together with the fact that the high pitch whine attenuates aggressively at distance, compared to much lower pitches. It’s likely that it has little benefit for anybody other than the user, in which case, hearing protection.
I’m sure this is a more broad accomplishment, but this has been a field of study across multiple industries for multiple reasons.

it’s electric.
Which means it’s automatically 200x quieter than a two stroke.
Idk what else they did but im pretty sure it makes almost no difference lmao.

As the article states, it’s this sound that they got rid of. A 94% drop in the high pitched shrill of the electric leaf blower.
Read. The. Article.
It’s a 2 minute read ffs.

So you’re not here to read articles ever? You’re just here to get corrected in comments?
