翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Perception of Infrasound ： ウィキペディア英語版 Perception of Infrasound Infrasound is an anthropocentric term that refers to sounds containing some or all energy at frequencies lower than the low frequency end of human hearing threshold at 20 Hz. It is known, however, that humans can perceive sounds below this frequency at very high pressure levels. Infrasound can come from many natural as well as man-made sources, including weather patterns, topographic features, ocean wave activity, thunderstorms, geomagnetic storms, earthquakes, jet streams, mountain ranges, and rocket launchings. Infrasounds are also present in the vocalizations of some animals. Low frequency sounds can travel for long distances with very little attenuation and can be detected hundreds of miles away from their sources. == Mammals == The production and perception of infrasound has been observed in multiple mammals, including whale, elephant, giraffe, hippopotamus, and rhinoceros. For most of these animals, observations are preliminary and their sensitivity to infrasound has not been quantified. If an animal produces a low frequency sound, and uses it in communication, it suggests the animal might also be sensitive to infrasound. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Perception of Infrasound」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
