Nano carbon fiber wire as low frequency wave guides

[extremesoundandlight@yaho]

Here is another concept take nano carbon fiber wire with a density x
amount then layer a nano wire of carbon around it with less density.
The difference in the carbon densities should form a wave guide for
sub sonic frequencies. the sound will travel faster through the dense
part of the wire and slower through the less dense wire trapping the
full sinusoidal wave form in its entirety as it propagates through the
mediums.

Why does that not seem plausible their JF can you chime in on that for
moment tell me why that won’t work in your mind
any thing other than
I see there are idiots in Tucson, too.

how about some constructive means why it does do just what I
explained.

You didn't explain anything. You just tossed out a half assed theory
with big enough holes to put our sun through. What frequency do you
consider sub sonic? A i Hz tone is roughly 1100 feet per cycle. HITH
are you going to squeeze that though something a few microns wide?

yes dip shit since sound travels much faster and more effiecient
through a solid than air or the space between your ears. the denser
the faster sub sonic sound travel through that medium thats why you
probly never heard any low frequecy whale mating calls when there on
the shore beeched you simpleton. sound travels through water almost
three times as fast and for much further distances. so the subsonic
frequencies just above and below whale and dolphine language is
considered subsonic

a full cycle of 1100 feet my seem long but its distance from peak to
peak of the sin wave can be sqeezed through easly but yes I do see
your point about a full cycle of low freq waves but how many feet peak
to peak for 1100 would be 550 right
yes I see why you think this is not possible. I may need to stop
smoking the crack.

It's not my job to show why it does what you think it does, that's your
job.

As Michael pointed out, you didn't explain anything, all you did was
hypothesize that sound could propagate down a carbon fiber (a 'nano'
fiber, whatever that means) if it was covered with more fiber of a
lesser density which was also propagating the same signal, and that
would make what would seem to be a sonic waveguide because of the
difference in c between the two.

Assuming that you could build a launcher which would couple acoustic
energy into the central fiber and its surrounding cage, simultaneously,
what makes you think that would give the structure the properties of a
waveguide?

Just thinking about it, why would the cage be necessary?

Certainly there's enough of an impedance difference between air and
carbon that even without the cage around the core the acoustic energy
would propagate down the fiber much like light down a light pipe without
escaping through the diameter.

But perhaps you meant that the phase difference between the core and the
cage, because of their differing c's would enhance the propagation in
some way?

It's hard to tell unless you attack it quantitatively.

Do you know what the velocity of propagation of sound is, longitudinal
and transverse, VS frequency, for the carbon fiber(s) you have in mind?

And, just as an aside, how do you propose to lower the density of the
cage cladding?

And, just as an aside, why is your idea valuable?

sound follows the inverse square law in water same as it does in air.



frequencies below those audible are considered infrasonic,
(contrast with ultrasonic)

subsonic means traveling slower than sound and (contrast with supersonic)

I've seen (and used) sonic wave guides of both the centre less-dense
and the centre more dense types.

an example of the former is a speaking tube
and an example of the latter is a taught-string 'telephone'

sound waves (especially those in fluids) are compression waves and
I predict they won't propogate down your nanotube waveguide well.
transverse waves might work on the other hand.

Im sorry when I stated nano carbon fiber I ment carbon wire but a
thicker version of how nano carbon fiber is made so its diameter is
much thicker.

I have a large acrylic water wall with a 15 inch speaker mounted on
the back with a vary loose suspention a low frequecy genarator with 15
whatt out-put attached in front of the water wall to the speaker, the
speaker with a vary stiff suspention in the basket to drive the sound
through the waterwall and the speaker im using as a transducer to pick
up the vibrations witch should propagate throuh the water to the
transducer. I will have the cabon fiber atteched to the transducer
leads so this shoud induce the low freq sounds onto the carbon wire.
what do you think

Im sorry when I stated nano carbon fiber I ment carbon wire but a
thicker version of how nano carbon fiber is made so its diameter is
much thicker.

I have a large acrylic water wall with a 15 inch speaker mounted on
the back with a vary loose suspention a low frequecy genarator with 15
whatt out-put attached in front of the water wall to the speaker, the
speaker with a vary stiff suspention in the basket to drive the sound
through the waterwall and the speaker im using as a transducer to pick
up the vibrations witch should propagate throuh the water to the
transducer. I will have the cabon fiber atteched to the transducer
leads so this shoud induce the low freq sounds onto the carbon wire.
what do you think

If, by: "transducer leads" you mean the terminals which are attached to
the voice coil, then the signal which will appear there will be
electrical, not acoustical, and if a fiber is connected to the terminal,
that electrical signal will propagate through the fiber as charge
flowing through a resistance.

Why does that not seem plausible their JF can you chime in on that for
moment tell me why that won’t work in your mind
any thing other than

how about some constructive means why it does do just what I
explained.

It's not my job to show why it does what you think it does, that's your
job.

As Michael pointed out, you didn't explain anything, all you did was
hypothesize that sound could propagate down a carbon fiber (a 'nano'
fiber, whatever that means) if it was covered with more fiber of a
lesser density which was also propagating the same signal, and that
would make what would seem to be a sonic waveguide because of the
difference in c between the two.

Assuming that you could build a launcher which would couple acoustic
energy into the central fiber and its surrounding cage, simultaneously,
what makes you think that would give the structure the properties of a
waveguide?

Just thinking about it, why would the cage be necessary?

Certainly there's enough of an impedance difference between air and
carbon that even without the cage around the core the acoustic energy
would propagate down the fiber much like light down a light pipe without
escaping through the diameter.

But perhaps you meant that the phase difference between the core and the
cage, because of their differing c's would enhance the propagation in
some way?

It's hard to tell unless you attack it quantitatively.

Do you know what the velocity of propagation of sound is, longitudinal
and transverse, VS frequency, for the carbon fiber(s) you have in mind?

And, just as an aside, how do you propose to lower the density of the
cage cladding?

And, just as an aside, why is your idea valuable?

Yes but today the transducer failed miserable I need to get a better
transducer and try it in a pool. so then sound db's or pressure waves
are converted as a current variance and then viewed on my laptop with
my fluke software both speaker and transducer need to be water proof.

---
If you want to convert them as a current variance then you'll need to
get one of those endless pools which generate a current you swim against
and use the gradient normal to its axis to calibrate your fluke
software.

But, be aware that the sound of speed in carbon fiber is 11600-21200
m/s, so that'll be much, much faster than any fluke can flap, which will
render your fluke software as useless as your premise.

   Rusty james state tyhat once the pressrue wave is converted through the tranceducer it is now a current propagating down the wire mesuring current variance so the sound of speed in carbon fiber is 11600-21200 m/s, has no relavance at this point so my fluke software will work fine but your right low frequency sound or rpessure waves wont propagate dow wire.

But subsonic waves induced as current variance through a transducer
will work just fine
