Mention was made of the use of sound supressers on private aircraft in the "flying in Europe" thread. I think this is topic that is totally ignored in the US and would like to address it. Im sure everyone in the US has experienced having to raise your voice in a conversation while sitting in your backyard because a small aircraft flying over so high you can barely see it ( about 10,000 ft) makes a sound loud enough to compare to a two-stroke dirt bike passing by a 100 ft away. Isnt it time that general aviation manufactures start investigating sound absorbing materials and muffling systems to use when designing their planes?
