Comment by Chris G on March 18, 2013 at 6:25pm That make sense Kolten. I should have read the small print or thought about it rather than taking it at face value. It might be visible at night with lights if the speaker freq was near 60 cps.

Comment by Chris G on March 18, 2013 at 3:59am At first I thought I wouldn't need to use my o-scope because the f-generator has a calibrated dial but after looking up Avian hearing thresholds and seeing frequencies as low as 30 Hz for Great Horned Owls I considered the other wildlife and nixed the idea as a permanent installation. Wildlife doesn't need another noise pollutant.
Comment by Tom Sarbeck on March 18, 2013 at 1:20am PS. Higher frequencies than we humans hear might bother neighborhood dogs.
Comment by Tom Sarbeck on March 18, 2013 at 1:18am Chris, if you also have an oscilloscope you can see your frequency generator's output.
Comment by Chris G on March 17, 2013 at 5:05pm I have a frequency generator and will do that in the back yard if I can find an cheap weatherproof speaker and it doesn't bother the birds.

Comment by Joan Denoo on March 17, 2013 at 2:33am A simple, few words, repeated many times, and at least the initials begin to fit a concept of E=MC2. Thanks Ruth.
That's why my pee does when I sneeze while taking a leak.
