Nabasala sam prije na Quori o RF hearing effect. Ovo je neki sažetak
The RF hearing effect, also known as the microwave auditory effect or the Frey effect, refers to the human perception of sounds when exposed to pulsed or modulated radiofrequency (RF) energy, particularly microwaves. Essentially, some people can hear sounds, often described as clicks, buzzing, or hisses, when exposed to specific types of RF radiation.
Here's a more detailed explanation:
How it works:
The effect is believed to be caused by the rapid heating and subsequent thermal expansion of brain tissue when exposed to pulsed RF energy. This rapid expansion creates thermoelastic waves that travel through the brain and stimulate the auditory system, mimicking the perception of sound.
Frequency and Pulse Characteristics:
The RF frequencies that induce this effect typically range from 200 MHz to 6.5 GHz, with short, strong pulses (around 30 microseconds or less) and long intervals between pulses, similar to radar signals.
Individual Variation:
Not everyone experiences this effect, and it's thought to depend on factors like the individual's hearing sensitivity and the specific characteristics of the RF exposure.
Weaponization Concerns:
There is some discussion about the potential for using the RF hearing effect as a weapon, as it could potentially be used to create auditory hallucinations or other auditory disturbances. However, there's no evidence that this has been done or that it's a viable military application.
Havana Syndrome:
The RF hearing effect has been mentioned in relation to the mysterious Havana Syndrome, where individuals have reported various health issues, including auditory disturbances. However, there's no conclusive evidence linking the RF hearing effect to Havana Syndrome.

The Frey effect ( microwave auditory effect, microwave hearing effect, or RF hearing ) is a phenomenon that occurs near powerful sources of pulsed radio frequency radiation . Some people are able to reproducibly perceive pulsed radio frequencies as clicking sounds without any additional aids (such as radio receivers ).
A description of the effect was published by the American neurologist Allan H. Frey in several articles starting in 1961. [ 1 ] [ 2 ] [ 3 ]
This phenomenon was discovered during World War II in people who were in close proximity to a powerful radar installation .
