The notion that electromagnetic energy can interact with human tissue and cause sensations – including perceived sound effects – is uncontroversial. This was suspected as early as the late 1940s and established experimentally in the 1960s. A good deal of the research was in fact conducted in prestigious, federally funded mainstream laboratories. Three names in particular have been associated with this research. Alan Frey, Leif Salford, and Olle Johansson. Another term for “microwave hearing” is the “Frey Effect”. There are further and somewhat troubling experiments, by Salford in particular, that raise serious concerns about the potential overall impact of cellular and wireless energy on human systems. That is a serious but different topic, which I leave to others.
NOTE: I do not claim that microwaves play any role in the world Hum – in fact I think it’s trivial to demonstrate that is not the case. The purpose of this reference list is to demystify the topic and to establish that EM radio energy can be interpreted as sound. I am pursuing the theory that VLF radio is responsible for most of the world Hum.

There are many similar studies. Those familiar with how these journal articles work will want to refer to the reference lists in the above articles. Examining the reference lists for those articles, and so on, will generate a working list of all the formal studies that have been conducted on these topics. This can take some time, but for those who are interested in doing serious research, it’s a process that must be done.
