Silencing Aircraft Engines: New Material Could Reduce Noise To That Of A Hairdryer

I actually like jet noise
It's a good news/bad news story. The good news is that jet engine noise will be reduced to that of a hair dryer. The bad news is that hair dryer noise will be increased to that of a jet engine.
But electric!
I don't think the jet efflux noise will be reduced in any way by this material.Hair drier? I think not.
I’m developing haberdashery for unicorns and magnetic chocolate teapots. Those might also reduce engine noise.
