BTW here's the cheapest [new] ultrasonic detector I can find ...http://www.amazon.co.uk/Discovery-Channel-D12-Ultrasonic-Detector/dp/B00DUNS8K8It's a toy but apparently it does work and you could conduct experiments to see if you are being bombarded with ultrasound, (which you are not) , and find out if ultrasound can penetrate walls & windows.

[attachment=19239]A jet-engine 100 feet away produces 140dB of sound energy.Have you noticed any jet-engine-sized equipment being installed within 100 feet of you ?,[ if it emitted ultrasound-only it would have to be closer and/or more powerful than a jet engine at 100 feet, as air transmits audible-sound better than ultrasound, and need to be louder-still if a wall separated you from the alleged source ].If the CIA / FBI / MI5 / B&Q / have miniatured these devices, and their huge energy supply, so they are not conspicuously visible, use your ultrasound-detector to track them down : the closer you are the louder it will become ... http://hyperphysics.phy-astr.gsu.edu/hbase/acoustic/invsqs.htmlAlternatively consider the possibility that the phenomenon is endogenous.
