The Microwave Auditory Effect

Abstract

Overview

The microwave auditory effect is a significant biological phenomenon triggered by microwave exposure. Unlike typical auditory processes that involve sound waves, this effect occurs when pulsed microwaves are perceived directly through electromagnetic waves.

Findings

• Absorption of a single microwave pulse can generate perceivable acoustic sounds like zips, clicks, or knocks.
• A sequence of microwave pulses may be heard as buzzes, chirps, or tunes.
• Extensive research involving humans and animals has led to these observations and the documentation of neurophysiological, psychophysical, and behavioral impacts.
• When microwave pulses are absorbed by head tissues, they generate a pressure wave that moves to the inner ear through bone conduction, activating cochlear receptors similarly to normal hearing processes.

Conclusion

Depending on the power of the microwave pulses, the induced sound pressure may exceed the auditory threshold, potentially causing tissue damage and presenting risks of both lethal and nonlethal brain injuries.
