Liked: Taos Hum Strange low-pitched sound coming out of nowhere in Taos, New Mexico. Source unknown. Listen carefully... NOTICE! High-pitched sound you hear is only electronic noise that appeard during the recording. Taos hum is super low bass sound in the background. If you can't hear it, it means that you're using bad quality speakers/headphones, or it's just impossible for you to hear such low bass sounds. via YouTube https://www.youtube.com/watch?v=EuRBM0i8mbI
