    The team reduced the overall leaf blower noise by about two decibels, making the machine sound 37% quieter.

    It’s an insignificant 2db, I don’t know why buddy didn’t provide the relevant information.

      Reading the article, reducing the shriller frequencies by 12db is still pretty nice, looks like it’s designed for electric blowers which are already way quieter than gasoline powered ones, already generally in the hearing safe range. 2db overall should still be noticeable though, be generally less annoying.
