Sure if you compare the loudest backpack blower to the quietest electric there’s a Night and day difference,.
But what about the quietest gas one compared to the loudest electric? I’ve got a 60v leaf blower, it’s iirc 13db louder than the 20v. And it’s far louder than a lot of gas ones people use for personal use.
If the deafening whine of a leaf blower feels inescapable, you’re not imagining it.
Leaf blowers produce a low-frequency buzz that “allows loud sound at harmful levels to travel over long distance and readily penetrate walls and windows,” said Banks, who published a peer-reviewed paper in 2017 analyzing noise pollution from the gas-powered lawn equipment.
The pilot study found that the loud noise produced from the machinery could travel up to 800 feet away from the source.
Short- and long-term exposure to noise pollution has links to a host of health impacts, including, in some cases, increased risk of heart attacks, strokes and other serious heart-related problems, and hearing loss. The Centers for Disease Control and Prevention lists gas-powered leaf blowers and lawn mowers among the sources of loud noise that can damage hearing over time.
Electric leaf blowers are quieter. After testing both types, Consumer Reports gave electric devices an average score of 2.9 for noise at the ear, compared to 1.7 for gas models. (The lower the score, the worse the noise.) And when the sound was measured 50 feet away, the electric leaf blowers earned an average score of 4.8 versus 2.5 for gas.
“It dissipates over a much shorter distance and it can’t penetrate walls and windows easily either,” Banks said.
This is a well known fact about how sound travels through the environment. Lower pitch noises (gas engines) tend to travel very far and very aggressively. They’re so much more potent.
High pitched whining sounds (electric motors) don’t travel nearly as well as lower pitch sounds, and they tend to be much much quieter at distance.
Combine that with the sound profiles of the ICEs compared to the constant whine of an electric motor in a certain part of the spectrum of audible sound. Now you have modulation on the ICE which is going to be much more potent to begin with, since it’s an entirely different sound profile. As well as being much harder to tune out, given the fact that it’s not just a persistent whine.
This is why the abrams powered by a gas turbine are known for being incredibly quiet, even though when up close, you can still hear them loud as shit. The sound just can’t travel through the environment as effectively, and like i said, even if it does. It’s not exactly the incredibly distinct sound of an ICE.
I mean sure you might have to wear hearing pro still. But that’s not my problem, what is my problem is having unavoidable hearing damage from my neighbors who are currently mowing.
I’ve got an electric powered one, it’s just as loud as a gas one, but still within municipal sound limits.
Sorry, find something else to complain about.
No it’s not.
Source: I have ears and have been around both.

TL;DR - Not only quieter but the sound from and electric leaf blower doesn’t travel like the sounds from a gas leaf blower.
Electric just as loud… WHAT? ARE YOU EVEN A HUMAN?
They produce the same DB the percussive sound of the engine travels further. At the point of sound they can be just as loud.
yeah, me and my homies mow and blow within ten meters of each other so that way we all share equal hearing damage.
Once you’re about that distance away you’re safe from hearing damage even if it’s annoying to listen to.
It’s only important for people using the equipment and their crew. If you’re that close, the fuck you doing that close lmfao.
i think you might have missed the joke
you’re very wrong btw.

I addressed that in another comment, at the point source the DB is the same, but the percussive sound of the engine travels further.
yeah, and that’s a good thing?
