This is mostly an engineering problem I think. The new Dewalt DCBL777Y1 leaf blowers are so quiet that even on loud I can use it in my garage without feeling like it’s loud or my watch triggering a sound alert. With my gas leaf blower, even outside it’s deafening and my watch immediately triggers. And the electric one is 2x more powerful than the gas one (in CFM, no bs about a smaller nozzle and “high mph”, the thing BLOWS). It also works upside down and doesn’t dump exhaust so I can use it inside as well as upside down when drying my car. No shill, I paid full price for mine and have no affiliation with Dewalt, just surprised and happy. I expected to return it because I didn’t believe it would be better than my gas blower. That gas blower has been on a shelf for the last 3 months. I’ll probably just sell it, there’s no use case where it’s better than the Dewalt except for long runtimes, which I don’t need.
