SUMMARY

The microwave auditory effect, also known as the Frey effect, is a phenomenon where individuals perceive sounds through the application of microwave radiation. This effect has been documented in various studies and is theorized to occur due to the rapid thermal expansion of tissues in the head, creating audible sensations. The discussion references a Washington Post article and a History Channel segment that question the feasibility of this phenomenon, highlighting a general lack of understanding among laypersons regarding its scientific basis.

PREREQUISITES
  • Basic understanding of microwave radiation principles
  • Familiarity with auditory perception mechanisms
  • Knowledge of thermal expansion effects in biological tissues
  • Awareness of scientific skepticism and media representation of scientific phenomena
NEXT STEPS
  • Research the scientific studies on the microwave auditory effect
  • Explore the mechanisms of auditory perception in humans
  • Investigate the implications of microwave radiation on biological tissues
  • Review media portrayals of scientific phenomena for accuracy
USEFUL FOR

This discussion is beneficial for neuroscientists, audio engineers, and anyone interested in the intersection of physics and human perception, particularly those exploring unconventional auditory phenomena.

I came across one article in Washington Post.

It was talking about "microwave auditory effect," which I had no idea of.
So, I have read the below regarding microwave auditory effect in wiki.
http://en.wikipedia.org/wiki/Microwave_auditory_effect

I still have no clue. Just jaw opening... How is it possible -
I also saw the History Channel "It's impossible."

I am depressed. I couldn't understand it at all regarding the possibility.
Except asking questions that I cannot write here
(otherwise, it would be deleted as a violating the rule of forum, received warning
as it shown below with yellow color >_<)

Is there anyone who can explain to me in easy terms, not physics term?
It will be really appreciated. Thanks -
