I loathe leaf blowers, so I often wonder what the acoustic design limits for a high speed air moving device are. How quiet could it be if the air source was impractically far away, and the business end was just a carefully engineered duct? Could the tone be changed into \
@ID_AA_Carmack Dyson could do it. Loud sound will probably arise from vortex shedding in the output structure or vibration. High modulus of elasticity materials and proper laminar flow design will enable fast flow without noise. Using an electric motor would be silent
@JonathanClaass4 @ID_AA_Carmack Rubbish. You clearly don't own any Dyson products. They are all really loud despite none having anything like the air moving demands of a leaf blower.
@JonathanClaass4 @ID_AA_Carmack If @Dyson could do this they would have made quiet hand dryers rather than ones that sound like jet engines
@JonathanClaass4 @ID_AA_Carmack Dyson convinced many to vote Brexit. I’m never buying Dyson products again (and I used to love his vacuums…now I use Shark…just as good, if not better).
