Noisy generator and ride lawnmower engines drive me crazy! Why not replace the 50 cent muffler they use with a car muffler and viola, I would assume it would be much quieter. This applies to mopeds too.

For the lawns, how about a reel cutter mounted in front of a Segway? |

Would the engine still be able to
breathe? |

Most of the noise from small engines like these is not from the exhaust. They tend to be air-cooled so don't have the sound-insulating effect of a water-jacket. |

What does the bowed string instrument do? |

I think the viola is designed to be played quietly and hide the remaining noise from the near-silenced exhaust. (sp: voila) |
|

This isn't a bad idea though, they are noisy things and thre would be a market for them with better silencers. |
|

I wonder if the reason the muffler is minimal is because a fully silenced muffler would involve too much of a penalty in engine output? Boy racer cars have custom air inlets and exhausts to boost airflow, and therefore power. |

Nuvess, our rabbit, has a round cage which he can push around on the grass, and that makes for an almost completely silent lawnmower. |

I love it and it gives me an idea, see "solar powered lawn mower". |
