Pure silence.

  1. Oct 19, 2013 #1
    Hello,

    How can one go about acquiring an effect of soundlessness on the brain? For example, as earplugs are to hearing capacity, the affect would be on the mind and brain.

    What? That implies that I would be dead or in sleep.

    With reference to the likeness in post #1, the affect on the mind and brain would be greater than that of the earplugs on the mind and brain, or hearing capacity.

    Etherialist.18, Can you be more specific? Your question is not worded so clearly and so members here are having difficulty giving meaningful responses.

    Are you asking what would happen if the mind/brain was deprived of all stimulus? This is known as "sensory deprivation" and a Google search brings up many examples. If yes, then why not list those mechanisms that serve to stimulate the brain? Then research each one, and the effects on the brain of "turning it off"?

    If this is not what you are asking about, please try again.

    No, I do not mean to sensory deprivation. In other words, I mean a taking away of sound from the external, and possibly internal, environment of the individual. For example, a unique head-set that I would wear that blocks sounds - though, I'd still see visuals, see my environment etc.

    It's very hard to totally block sound. Ear defenders work to an extent but very loud sounds don't just go in through the ear, they physically shake/vibrate the whole body.

    Just Google "noise cancelling headphones".

    I have those already. Would gun ear muffs be better? I'd like a tool to block all sound frequencies etc.

    When you're wearing sound-cancelling headphones, what do you hear?

    You can experience the real thing by visiting an anechoic chamber.

    They are used in research projects with sound; you may find one at your local university - look for a professor who specializes in acoustics; they will know.

    I don't understand what you were originally asking about, in that you inferred your requirement was different than earplugs.

    That said:
    Consumer grade active noise cancelling headphones have their place, but are not really all that quiet.

    The highest rated earmuffs are around 33dB (NRR) ( http://www.amazon.com/Pro-Ears-Passive-Hearing-Protection/dp/B00117XML0/ref=pd_sim_sbs_sg_1 ) , and earplugs go to 33dB. Supposedly wearing them both only gains you, like, 10dB more.

    Remember there is sound conduction through your mouth and skull also.

    Going into an anechoic chamber you can hear the blood pumping in you ears. There is no silence - you become the noise maker.

    Which is really weird!

    I definitely agree. If the OP is looking for total silence, ear plugs only make the sound of breathing and pulse more noticeable.

    I'm not clear that the OP knows WHAT he is looking for. Seems to have changed over the course of the thread.

    Repeated and prolonged exposure to extremely loud sounds has been shown to reduce the functionality of the ear's ability to hear. You could try that until you don't hear anything anymore.

    Are there specific sounds that are a problem? As meBigGuy and edward explained, you won't be able to hear absolutely nothing, even if you just hear yourself. You just have a choice what to hear (and how loud).
