Yup, electromagnetic pulses are all around us all the time. High tension power lines on tall utility poles are thought to affect mammals--one study found that cows become disoriented near them.
When I was in the Navy aboard a carrier flight deck, I would sometimes hear a repetitive buzz or a pinging sound that was so soft, I'm sure no one else heard them. My hearing discrimination was naturally really good, so I was trained to detect the tiniest differences in sounds, and my job was in Electronic Intelligence--operating equipment that would locate enemy radars, missiles, and such.
Keep in mind that, in order for something to make any sound, it has to physically move an object (usually a speaker), vibrate it just a little. When I looked for the source of the sound, I discovered it came from the ship's long range radar. Every time it pointed in my direction, my plastic noise protection (Mickey Mouse ears) would rattle a bit.
Also, while I was inside of an aircraft repairing the equipment, there were times I would notice a faint vibration of the toolbox next to me. So I went outside and saw it was the altitude finding radar on the helicopters overhead, pinging me.
Even today, I often hear the tiniest buzzing noises while driving down the highway, and then look up to see jumbo jets preparing to land. I can tell (from training) that their radars are scanning the area.
Every radio and TV station, every police speed trap, and even the WiFi in your house and at Starbucks are sending EM waves through our bodies. And of course our cell phones are right there, next to our brain, emanating EM waves. The Navy even has a giant antenna under the ground in Virginia that communicates THROUGH the Earth to the other side. And then, there's my laptop computer, literally sitting on my lap, transmitting to the Cloud...
If electric waves caused ALS, every American would have it by now.
