The brain can perceive microwaves as sounds in a phenomenon known as the Frey effect. Over time, targeted microwave energy could induce head injury. A microwave weapon, according to the New York Times, could look like a satellite dish and may be handheld or fixed to a variety of transportation. Citing research, the New York Times reports that U.S. diplomatic staff in Cuba experienced intense high-pitched sounds inside their hotel rooms and homes.   University of Pennsylvania brain expert Douglas Smith told CNN the injuries are like &#8220;like a concussion, but without a concussion&#8221; as patients had no previous head trauma. A senior U.S. administration official told CNN authorities suspect the injuries were caused by microwave beams, but added that they have no solid evidence.   <\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-embed-wordpress alignright wp-block-embed is-type-wp-embed is-provider-rh-negative-blood-and-people\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"2T5ZrzX2e4\"><a href=\"https:\/\/www.rhesusnegative.net\/staynegative\/the-electromagnetic-field-of-the-heart\/\">The electromagnetic field of the heart<\/a><\/blockquote><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; clip: rect(1px, 1px, 1px, 1px);\" title=\"&#8220;The electromagnetic field of the heart&#8221; &#8212; The Rh Negative Blog\" src=\"https:\/\/www.rhesusnegative.net\/staynegative\/the-electromagnetic-field-of-the-heart\/embed\/#?secret=eh9lPk0FXE#?secret=2T5ZrzX2e4\" data-secret=\"2T5ZrzX2e4\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Allan H. Frey was the first American to publish on the microwave auditory effect (MAE). Frey&#8217;s &#8220;Human auditory system response to modulated electromagnetic energy&#8221; appeared in the&nbsp;<em>Journal of Applied Physiology<\/em>&nbsp;in 1961.&nbsp;In his experiments, the subjects were discovered to be able to hear appropriately pulsed microwave radiation, from a distance of a few inches to hundreds of feet from the transmitter. In Frey&#8217;s tests, a repetition rate of 50&nbsp;Hz was used, with pulse width between 10\u201370 microseconds. The perceived loudness was found to be linked to the peak power density, instead of average power density. At 1.245&nbsp;GHz, the peak power density for perception was below 80&nbsp;mW\/cm<sup>2<\/sup>. According to Frey, the induced sounds were described as &#8220;a buzz, clicking, hiss, or knocking, depending on several transmitter parameters, i.e., pulse width and pulse-repetition rate&#8221;. By changing transmitter parameters, Frey was able to induce the &#8220;perception of severe buffeting of the head, without such apparent&nbsp;vestibular&nbsp;symptoms as dizziness or nausea&#8221;. Other transmitter parameters induced a&nbsp;pins and needles&nbsp;sensation. Frey experimented with nerve-deaf subjects, and speculated that the human detecting mechanism was in the&nbsp;cochlea, but at the time of the experiment the results were inconclusive due to factors such as&nbsp;tinnitus.<\/p>\n\n\n\n<p>Auditory sensations of clicking or buzzing have been reported by some workers at modern-day microwave transmitting sites that emit pulsed microwave radiation. Auditory responses to transmitted frequencies from approximately 200&nbsp;MHz to at least 3&nbsp;GHz have been reported. The cause is thought to be thermoelastic expansion of portions of auditory apparatus, and the generally accepted mechanism is rapid (but minuscule, in the range of 10<sup>\u22125<\/sup>&nbsp;\u00b0C) heating of brain by each pulse, and the resulting pressure wave traveling through the skull to the&nbsp;cochlea.<\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube aligncenter wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Rh Negative Superpowers: Electrokinesis\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/dVdWnSCUI6M?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>In 1975, an article by neuropsychologist Don Justesen discussing radiation effects on human perception referred to an experiment by&nbsp;Joseph C.

Since the radiation levels approached the (then current) 10&nbsp;mW\/cm\u00b2 limit of safe exposure, critics have observed that under such conditions brain damage from thermal effects of high power microwave radiation would occur, and there was &#8220;no conclusive evidence for MAE at lower energy densities&#8221;.<\/p>\n<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/static.hupso.com\/share\/buttons\/share-medium.png?w=640&#038;ssl=1\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"What is the Frey effect?\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>","protected":false},"excerpt":{"rendered":"<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img src=\"https:\/\/static.hupso.com\/share\/buttons\/share-medium.png\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"What is the Frey effect?\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the&nbsp;human perception of audible clicks, or even speech, induced by pulsed or modulated radio frequencies.
