  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.

    Good job not reading any part of the article and confidently announcing your completely incorrect take on things to everyone.

      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.

        As the article states, it’s this sound that they got rid if. A 97% drop in the high pitched shrill of the electric leaf blower.

        Read. The. Article.

        It’s a 2 minute read ffs.

        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)_/¯
