Ultra-Sound: Mouse repellent to muscle warmer

Short post. ..  possibly one for future development..  but I couldn’t resist comparing the wonders of ultra-sound – well, more of the ways in which we now use it.

Only yesterday I was at the Osteopath, and he was using a sort of ultrasound hand-held device to warm up my back-muscles, before the twisting and manipulating  the spinal column . And today while at a diy hardware store, I came across sonic mouse repellent gadget!  Quite amazing how we use sound now in everyday life.

That’s excluding the professional expert use of ultra-sound .. in radars (well, actually sonars in submarines), and ultrasound scans of pregnant women (which is non-evasive and harmless, compared to say an x-ray!).  There are side effects, a sure – in the case of Sonars in deep seas, it must surely affect some marine life that (well, nearly all of them) depend on sound vibrations to detect food or dangers; In the case of a baby- well, although human hearing does not encompass the ultra-sound ranges, no telling if some developing embryos may well `hear’ it?   After all, some people are susceptible to EM waves (electromagnetic) – people who live under power lines, people who are surrounded by electric equipment..  and me!

Oh yes, sometimes I do get a tingle and a kind of head-achy sense, just before a text arrives on y mobile phone..  way before any nearby radio speakers buzz and tweak.  That used to happen with the older mobile phones (not so much now). Okay that’s more radio waves, but still he point I make is..  people may be picking up these things, so unborn embryos might do..

Okay, leaving that debate aside – I am still marveled by the advancement of technology!
