10 comments on “Hum, Vibration and Rumble in Costa Rica : Jan 9

  1. That sound in the first video sounds exactly like the Colorado video, even to the point that you could hear the gravel moving from the guy walking.

  2. I’ve been watching videos and checking out this blog for hours, and man, I’m getting freaked out. What in the world is going on? What kind of phenomenon makes that kind of sound, be it man or nature?! O.o

  3. Here are reports on similar phenomena from three major news outlets:

    New York Times:
    http://www.nytimes.com/2003/12/02/science/here-and-there-mysterious-hum-bedevils-unlucky-few.html?src=pm

    BBC News:

    ABC News:
    http://abcnews.go.com/blogs/lifestyle/2011/10/viewers-guess-what-causes-the-mysterious-hum/

    And four academic articles:

    Cowan, James. “Kokomo Hum.” Acentech Consultants. Acentech, 1 Oct. 2003. Web. 19 Nov. 2009.

    Moir, T.J. “Auckland North Shore Hum.” T.J. Moir Personal Web Page. Massey University, 1 Mar. 2007. Web. 19 Nov. 2009.

    Deming, David. “The Hum: An Anomalous Sound Heard Around the World.” Journal of Scientific Exploration. 1 Oct. 2004, Volume 18, Number 4: 571-595.

    Mullins, Joe H., Poteet, Horace. “A perceived low-frequency sound in Taos, New Mexico.” Journal of the Acoustical Society of America. 1 Nov. 1994, Volume 96, Issue 5: 3334-3334.

    And one Wired article positing an explanation:

  4. I don’t think that the actual occurrence of the noise heard in Costa Rica is a hoax rather that the news station used the sound from the Colorado occurrence as any news source would use stock video of a tornado or lightning strike etc. As someone who speaks fluent Spanish, the news caster nor anyone reporting on this story ever claimed that the noise heard was the exact noise played but was rather quite similar. I don’t think that you guys should be so quick to dismiss the incident as simply a hoax.

  6. I picked up on this topic from one of the forums I am on. The opinions there are mixed. I am going to pay attention to the sky I think for the next little while. I live on an acreage in southern Alberta and you can hear a pin drop if there is no wind. I can promiss you that if I ever hear something like any of these videos claim, I will record it and there would be no BS. This site will be the first place it is sent. Luckily there is lots of work in the area, oil/gas drilling, siesmic crews, logging, etc. Hopefully this can be proven real or fake soon.
