Beginning in late 2016, diplomats posted to the United States embassy in Cuba began to experience unexplained health problems including ear pain, tinnitus, vertigo, and cognitive difficulties which reportedly began after they heard strange noises in their homes or hotel rooms. In response, the U.S. government dramatically reduced the number of diplomats posted at the U.S. embassy in Havana. U.S. officials initially believed a sonic attack might be responsible for their ailments. The sound linked to these attacks, which has been described as a high-pitched beam of sound, was recorded by U.S. personnel in Cuba and released by the Associated Press (AP). Because these recordings are the only available non-medical evidence of the sonic attacks, much attention has focused on identifying health problems and the origin of the acoustic signal. As shown here, the calling song of the Indies short-tailed cricket (Anurogryllus celerinictus) matches, in nuanced detail, the AP recording in duration, pulse repetition rate, power spectrum, pulse rate stability, and oscillations per pulse. The AP recording also exhibits frequency decay in individual pulses, a distinct acoustic signature of cricket sound production. While the temporal pulse structure in the recording is unlike any natural insect source, when the cricket call is played on a loudspeaker and recorded indoors, the interaction of reflected sound pulses yields a sound virtually indistinguishable from the AP sample. This provides strong evidence that an echoing cricket call, rather than a sonic attack or other technological device, is responsible for the sound in the released recording. Although the causes of the health problems reported by embassy personnel are beyond the scope of this paper, our findings highlight the need for more rigorous research into the source of these ailments, including the potential psychogenic effects, as well as possible physiological explanations unrelated to sonic attacks. 0096名無しさん@1周年2019/01/08(火) 13:43:34.52ID:lSeqT1PE0 7キロヘルツって可聴域じゃないの? 0097名無しさん@1周年2019/01/08(火) 13:43:59.11ID:4aARa7mZ0>>1 その昆虫兵器を外国大使館周辺に大量にバラまくという最新テロ 0098名無しさん@1周年2019/01/08(火) 13:44:23.56ID:Qp6nCQCI0 で?誰かが流してたのか? 庭に大量発生してるだけで被害があるのか? 0099名無しさん@1周年2019/01/08(火) 13:44:25.23ID:YveaG7MN0 ウチの回りにも夏になるとキーンというか ピーンというかモスキートノイズ的な音出す虫いるよ 0100名無しさん@1周年2019/01/08(火) 13:44:37.66ID:iLCoZdhN0 一方日本人は虫の音を楽しんだ (´・ω・`) 0101名無しさん@1周年2019/01/08(火) 13:44:58.85ID:YTrllqhQ0 国防省はキューバに謝れよ。 いつものように、軍需産業およびウォールストリート、さらにそいつらにカネもらった政治家やマスコミが、ありもしない架空の敵を作り上げ、軍事費増やし、くすねて、私腹肥やそうとしたんだろ。 0102名無しさん@1周年2019/01/08(火) 13:45:03.27ID:zPZqA61tO>>99 オケラ 0103名無しさん@1周年2019/01/08(火) 13:45:11.49ID:Fcu276uH0 不規則な騒音はイラッとくるね 0104名無しさん@1周年2019/01/08(火) 13:45:14.58ID:1l0SHnYs0 コオロギ養殖してアメリカ大使館の周りに配置するテロ 0105名無しさん@1周年2019/01/08(火) 13:45:34.76ID:iLCoZdhN0 日本大使館員「その攻撃はできたら秋に頼む」 0106名無しさん@1周年2019/01/08(火) 13:45:39.24ID:zPZqA61tO 清虫終式 0107名無しさん@1周年2019/01/08(火) 13:46:04.99ID:YTrllqhQ0 外交官の病気なんて、どうせ、パリかロンドンに出張すれば治るんだろ。 クズしかいないな。 0108名無しさん@1周年2019/01/08(火) 13:46:17.61ID:hIxDQ9df0 虫の声が聞こえないケトウw 0109名無しさん@1周年2019/01/08(火) 13:46:20.34ID:D6wf6pYX0>>2 こうろきさとみってか 0110名無しさん@1周年2019/01/08(火) 13:46:20.90ID:ddzl9ZrV0 韓国海軍「日本海にもレーダー波を発するウミガメが!」 0111名無しさん@1周年2019/01/08(火) 13:46:22.78ID:YTrllqhQ0 パリかウィーンかな? 0112名無しさん@1周年2019/01/08(火) 13:46:35.98ID:b2ANhyAI0>>101 まだ確定してない サンフランシスコでこれまでの調査結果がとりあえず発表されただけ 0113名無しさん@1周年2019/01/08(火) 13:46:54.03ID:IDcFeSUq0>>1 これは恥ずかしいw
