And since electric leaf blowers often have a much higher pitch, that pitch attenuates at a much greater rate

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.

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.

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

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.
