Abstract

Acoustic transients can be thermally generated in water by pulsed microwave energy. The peak pressure level of these transients, measured within the audible frequency band as a function of the microwave pulse parameters, is adequate to explain the "clicks" heard by people exposed to microwave radiation.

Main findings

Pulsed microwave energy can thermally generate acoustic transients in water. The measured peak pressure levels within the audible frequency band were reported as adequate to explain clicks heard by people exposed to microwave radiation.

Outcomes measured

microwave hearing (auditory clicks)
thermoacoustic acoustic transients/pressure within audible band

Limitations

No population/sample size described in the abstract.
Exposure frequency, intensity (e.g., SAR), and duration are not specified in the abstract.
Study design and experimental details are not provided in the abstract.
