The only EM field the human body radiates is infra red (heat). It can warm a wall but not pass through a wall.

If you are referring to electro-magnetic fields, then there is only one kind of field. Unless you mean something different my kinds of EM field, such as geometry of said field, or perhaps different sources of EM field in the body. The field produced by the body, I think, is very minute, so you would have some trouble measuring it at any real distance. It would go thru walls, unless the body were inside of a faraday cage. But, I do not think that you would be able to distinguish it from background noise.

A great spectrum of frequencies,like EM waves,or EM fields,there are,but depends on wall-s nature how much are decreased.

all kinds...provided of course that we're talking about wood framing (residential) vs steel framing (commercial). If it were steel framing, an EM field would be altered, shunted, and sometimes retained...dependent on the situation. why?
