Abstract

Overview

The study explores the phenomenon known as the microwave auditory effect, a significant biological effect of microwave exposure on auditory perception. Specifically, it investigates the perception of sounds produced by pulsed microwaves and their potential to cause tissue damage.

Findings

• Perception: Pulsed microwaves can be heard as distinct sounds such as zips, clicks, buzzes, chirps, or tunes by humans.
• Mechanisms: The microwave pulses, once absorbed by head tissues, generate a pressure wave that travels via bone conduction to activate cochlear receptors.
• Threshold of Perception: The induced sound pressure can significantly exceed the threshold of perception leading potentially to tissue injury.

Conclusion

This study demonstrates the lay of converting microwave pulses into sound, with potential risks of tissue damage and explores its utility in biomedical imaging, illustrating its dual capacity for harm or clinical benefit.
