January 9 2013 – Willoughby, Ohio. These high-pitched weird sounds were recorded at around 11 A.M. in Ohio. They seem to be a kind of siren malfunction. However what makes me think a bit more about it is the length of the malfunction (about 5 minutes tells the recorder) and the reverberation of the noise (sometimes louder than other, maybe the wind?). The weird noises as started abruptly as they finished. Well what do you think about this recording. Probably a siren but for what? Any idea? But it sure is creepy.
