My house vibrates!

Discussion in 'Miscellaneous [BG]' started by Nomadic Herder, Nov 15, 2001.

  1. I've been playing around with my amps and basses lately. If I play an F (1st fret E or 13th fret E, somewhat on 8th fret A) the whole house starts to vibrate. The amp isn't set very loud. Is everything in my house tuned to F? Why would it do this? It's fun nonetheless. :D

    My practice room has metal horizontal blinds. If I turn up too much, they sound like a junk truck on a potholed road!
  3. i have it when i strike the E on my B-string... makes a lot more bass than the open E

    Welcome to the wonderful world of Resonant Frequencies!
  5. The Eb on the thirteenth fret of my D string makes my house vibrate and my ears hurt.

    here a little thing to do

    lay down on your bed or something else soft and put your amp on your chest (if it doesnt crush you that it) now turn it up full and play the lowest note you possibly can play

    on a more respectable note, then i put a plectrum(there that word again:eek: ) on a cd cover and i play a low note it sometimes vibrates and all the goo inside my lava lamp goes all weird when i play F..but it only happens on F....

    Yeah, I find most of the notes on the E string past fret 12 vibrate on my bass.

    You guys ever read "The Big U" by Neal Stevenson? A guy takes out a huge university with resonant frequency.
  10. There was a TV programme on here in the UK last week about ancient burial chambers amongst other things. They discovered that many of them have the same resonant frequency...... spooky! They even thought that the cavities had been 'tuned' to that particular frequency by placing large stones inside them as baffles. Sorry can't remember what exact frequency it was.

    Also, they showed that some ancient configurations of standing stones can actually amplify the sounds made in front of them.... almost as if they were built as an auditorium.

    I would LOVE to see that show! Having participated in ritual chanting, it would be a real trip to do it in a chamber that is resonant to the freq range of the chant. Major power raising!

    Do you recall anything at all about the resonant freq - was it in the human voice range?

    Also, do you remember what circles they were at? We noticed a similar effect at Hurlers on the Bodmin Moor.

    Anything around a low A will rumble my walls in many different rooms. Sometimes there will be a jammin' party at my house with PA and everything. The house really shakes then.

    My band tunes to C. When I play an A# on any string the drummers snare will rattle really bad.

    I once read somewhere about a guy who supposedly went to a skyscraper that was in the process of being build. They had build only the steel skeleton of the building. That guy taped an electric toothbrush to some steelpart at the base of the building, turned it on, and went for a walk. When he came back the whole skyscraper had started to shake and everybody was in panic. The guy just took the toothbrush off and the building stoped shaking.
    Seems like the toothbrush had excatly the resonance frequency of the building.

    If your really patient you can empty out a bathtub just by moving one of your hands a little bit in the water. You just need to hit the right freq.

    it's time to call a skilled carpenter!
  16. A True Lo Freq Story - We finish playing a monstrous bass song, "Rocky Mountain Way" (Joe Walsh), and go on break. The guitarist and me go up to the bar of this dive and he orders a beer for himself and a bourbon for me. The bartender says, "Your bass player's going to have to take that in a beer mug."

    The guitarist says, "Run out of glasses???"

    Bartender replies, "NO - Your bass player knocked all the cocktail glasses off the shelves on that last song."

    Ahhh! 3x15, 450W, reverse-W enclosure :D
  17. i had a friend of mine over the other day and i played an A on the E string and he actually started to cry! it was hilarious. i didn't even have the amp set half way and it made him cry.

    You can have some fun with resonant frequencies. Try butting the headstock of your guitar up to the wall (works better on dry wall than plaster). Then play. The effect is awesome with a guitar but still noticible with a bass.

    Isn't it true that 7 Hz is the resonant frequency of a chicken's head? Seriously, I heard that if you emit 7 Hz to a chicken for a while, their head will explode, or something to that liking.

    I haven't heard that one. I have heard that there is a very low frequecnt (sub-audible) that will make ones bowels loosen. You would want to save that sort of special effect for the last encore.
