Effects of low frequencies on heart devices?

Discussion in 'Miscellaneous [BG]' started by bassman1185, Aug 20, 2001.

  1. I've heard that low frequencies can really screw up pacemakers and other heart-related devices. I've played in a couple of nursing homes, and I play regularly at church (we have a lot of elderly people at my church) and I have to think that it would really stink to kill somebody because I was a little too loud. Does anyone know about this?

    I don't know about the heart, but I heard that ultra low frequencies can induce bowel movements. :D

    Well....... I think if you are playing and nobody┬┤s getting at least a headache, then you need more volume... :):D

    My uncle (five years older than me, more like a brother) has always wanted to mount a 15" speaker in the end of a 6 foot piece of PVC sewer pipe, drive it with a big head, and see if he can knock people over using it as a "sonic bazooka". (He saw the movie "Scanners" a few too many times.) Every time he brings it up, I ask his doctor to increase his lithium dosage...
  5. Low Frequencies will:
    drive out vermin,
    induce labor,
    make beer go flat,
    have groupies fall in love,
    stimulate bowel movements,
    some ear bleeding,
    cause richter scale activity,
    irritate barkeeps,
    make booties shake,
    and attract all manner of law enforcement, but
    I've never heard of it causing heart problems yet. What I have heard, however, is TURN IT DOWN!
  6. That would be amizing!!!!!!!!!!!! you could play different notes to shoot out different power shots. Personaly i would use a small diameter pipe, then the blast would be more concentrated. That would be great. I think it's possible
  7. heheh, cool !

    so if i turn my amp up real high and do some speed-slapping, some dude with a pacemaker will start to breakdance ?

    :D !!

    Ok, i heard, i only heard so don't shoot the messenger, but there was a dude with a thumping phat car stereo. He was driving along with mates no doubt, and the hardcore bass took over the rhythm of his heart beat, so likewise when he got out the car he dropped dead.

    no, but someone may hack off your thumb.

    I've played in front of some elderly people, they didn't seem like they were having coronaries.
  11. Hell, I'm in trouble. I dont have a pacemaker, but I do take heart medication.....and I looooove my B string!

    Alright, let us clarify one thing. I think bassman1185 is confused with the terminology - there are different sorts of "low frequencies". Bassists like us deal with low frequency sound - the range that we play in even if you go down to the lowest note will have NO effect on pacemakers.

    The type of low frequency that affects pacemakers and other electrical devices are electric and magnetic low frequencies - these frequencies are known as ELF or "extremely low frequencies".

    An excerpt from the World Health Organization site:

    "EMF Interference

    Strong ELF fields cause electromagnetic interference (EMI) in cardiac pacemakers or other implanted electromedical devices. Individuals using these devices should contact their doctor to determine their susceptibility to these effects. WHO urges manufacturers of these devices to make them much less susceptible to EMI."

    The link is here:

    WHO website about ELF

    Other links of interest about ELF:

    International Programme of Chemical Safety Site

    National Health and Occupational Safety Commission of Australia

    So feel safe that as a bassist, the only way you would kill an elderly person is if you play really bad music, or hit them on the head with your bass. :)

    In the village where I live there is a guy who owns a van with a massive sound system. He uses it for competitions and stuff like that. It seems that he was in the top 5 loudest vehicles in Ontario. Anyway, when he really cranks up the volume he says that your heart will try to synchronize itself to the bass. And if he cuts the music too fast you could die. So he has to turn it down gradually. But then again he could just be full of **** and he's trying to impress people.

    Not "could be"; "is". IMO that crap should be illegal and the dudes making that level of noise in residential areas should serve time. But that's another subject...
