Pololu - Understanding Destructive LC Voltage Spikes
"There are several ways to limit the magnitude of the initial LC transients:
- Limit lead inductance
- Add resistance to the LC circuit
- Add a large, high-ESR capacitor across (in parallel with) the low ESR capacitor"

SMPS noise reduction - forum.allaboutcircuits.com
"The frequency at which the noise repeats is not what you have the problem with: look at the noise waveform. The sharply rising edges have components that go into the hundreds of Mega Hertz. That's whay they are so hard to kill"

"Use a low pass filter. As stated, you must use caps that are good at mega hertz ranges like ceramic caps and possibly polyester film caps. Aluminum electrolytics and tantalums will have very little effect since the noise frequencies are above their resonant frequency."

More good stuff in this thread...

Vermont Is Currently Enacting Some Of The Most Restrictive Rules On Wind Energy In The US | CleanTechnica
A new rule says wind turbines can’t be louder than a quiet library. It will stifle Vermont’s wind industry. Conservationists love it.

This Cleverly Designed Park Reduces Noise Pollution Around Amsterdam's Busy Airport
Paul De Kort and his team did research into the physics of sounds and stumbled upon the work of the German physicist and musician named Ernst Chladni. Chladni is sometimes referred to as the ‘grandfather of accoustics’. The design team used his principles to design a series of hedges and ditches southwest of the airport. They sit approximately 36 feet apart, the distance of the wavelength of the airport noise. The simple design intervention has caused the noise levels from the airport to drop by half.
