Electric leaf blowers are already far quieter than their gas-powered peers, but they still aren’t the kind of thing you’d like to hear first-thing on a Saturday morning. Looking to impr…
If it were me that designed this, I would license out the design for manufacturers to use in their production models instead of making some kind of attachment that is unlikely to work on all models. That seems much more likely to achieve the goal of reducing noise from leaf blowers long term. Get like 3 manufacturers on board that could even charge a premium, and you have reduced the noise potentially forever while still making a tidy profit.
