I'm sorry buddy but that just isn't convincing to me, what about how these ghosts are talking. I want to know how you know what wavelength to use, articles showing the tools efficacy. If I listen to static long enough I bet I'll start hearing stuff. Ghost kinda violate the first and second laws of thermodynamics. How do they take energy and produce it into a wave? If they don't eat or absorb energy it violates the first law.
Do you see or hear animal ghosts?
Where do ghost get energy?
Why is a ghost web made of?
Again, this seems to be a long thread debating the existence of the spririt world. I'll answer your last question and then I am done. Trying to figure out what "helps" those on the other side communicate is part of the science. Electromagnetic fields do seem to have a large impact, so does water, the wind, and things like "white noise". It seems they are able to manipulate those things to get it out. If it was easy to explain, it would be easy to explain. Kind of like trying to explain the "flex" defense to someone who doesn't even know what football is. If you are really interested, do some research. If you want to experiment yourself, PM me and I will be happy to help. I wish you all the best and appreciate your questions, but I'm pooped............AND Baylor is playing UW.
Sorry, I did not really fully answer your question. Yes, noone like to "listen" for something for too long. The sound is usually very clear with the digital recorders and what you do is ask questions, wait about 30 seconds for an answer (it can be very difficult for them) and move on to the next question. Many times, we will get EVPs that are comments about what we are doing. The most common, and sad, is "help". I use Adobe Audition software. Check it out. It really is not that hard to do EVP research!!
Check out some websites about EVP. I think there is one called Voices on the Wind that used to be pretty good and had some good EVPs.
