此外，由于引擎（发动机）外部运动较慢的空气覆盖了高温燃气排出引擎后部时的噪音，“高旁道比”（高涵道比）飞机的噪音指数下降了80%左右。
They are also some 80% quieter because the mass of slower-moving air shrouds the noisy hot gases coming from the rear of the jet.
尽管如此，Hemcrete的独特属性——热容量、碳负极、空气可渗透性等等——使得它成为外部围护结构的首选。
Nevertheless, the unique properties of Hemcrete - thermal mass, carbon negative, air permeability, etc - made it the first choice for the external envelope.

“这和向火焰上吹空气非常不同”Cademartiri说，“向火焰上吹气时，是在火焰外部产生气流并将空气推入火焰中。”
"This is quite different from blowing air on the flame," Cademartiri said. "When you blow on the flame, you generate flow outside the flame and you push air into this flame."
