今天听“活络位子”的时候，有一飞机经过，给予灵感？
飞机在空中飞过，我们在地面上听到的是什么频段的声音？
还有，想问阿邓兄：“音障”——是指飞机在接近到超越音速的时候产生的一种对飞机机械结构和各种飞行条件的综合障碍，对于声音的反映来讲，有什么启迪吗？当年突破音障时所有的对声音研究有没有应用在今天的音响研究上？——这个音障的研究成果如果能够应用上，我想：应该是一种极致的突破！

It counts on the distant of the jet. Most of people staying at
home cannot feel great impact of the jet engin while they are
taking off and the sound energy is not that great.

But if you live very close to the airport, then the impact would
be great.

Sound barrier happens when the jet flies up to the speed of the
sound (speed will change with atmospheric presure and
temperature), then it will produce sound blast.
There is no implication of sound blast could apply into audio,
but even  any speaker cannot produce nicely the sound
pressure of the jet engine. Save you time.

I can tell you one fact that in Heathrow Airport, London,
whenever the Concord take off on the runway, most of the
cars in the parking lot nearby, was stimulated by the roaring power of the jet engine and start to sing like a symphony.
But other jets would do the same. It's quite amazing

大家可要放心哦，“防尘帽”很快就会有“结论性”的成效的。
