Anyone who sincerely believes electric leaf blowers are - on average - even close to as loud as gas-powered blowers has to be arguing on the smallest of small sample sizes or bad faith. They're not comparable, there's a reason community-driven pushes to ban leaf blowers focus on those with combustion engines.

Can an electric leaf blower be as loud as a gas-powered one? Sure. I'm sure under the right circumstances a Prius can make noise comparable to Corolla too. Electric leaf blowers aren't silent and are often loud, but not aggravatingly loud. They won't make your next-door neighbors lose their mind, much less your neighbors two doors down.

The above poster isn't saying electric models are quiet, just that they are quieter than a similar gas model. Which makes sense when you think about it. Both of them probably have similar air turbulence noise of the blower part, but an electric motor is almost always way quieter than a bunch of pistons rattling about and having fuel-air mixture detonations.
