msb-0233 Hermann Ludwig Ferdinand von Helmholtz

msb-0233 Hermann Ludwig Ferdinand von Helmholtz


Feedback comes first, so...

I am bringing up Helmholtz because it saves me from thinking about a depressing weekend spent with my mother.

One bright spot was seeing my sister again, but I still feel pretty bad.

Today the music is semi-quasi-pseudo classical because, just because.

I needed the distraction.

Feed Forward comes next, so...

This is "your" segment.

Say "your" piece on this segment.

Share with other MSers whatever "you" want to share.

Drop me an email: charles at

And I would apreciate if someone could write a review of this podcast on iTunes [ ] You can just select the link and, eventually, scroll down the iTunes page to "Customer Reviews"

Feed Me comes third, so...

Do you have a therapy, product, good or service that is of interest to MSers?

Consider advertising on this podcast.

Reminders on this segment only cost $0.03 per reminder per download of an episode. (A $30CPM targeted at MSers.)

It can/should lead to a full ad, in text, audio or video, which costs $3.00 per download.

That sounds expensive until you do the math and realize that if nobody downloads it it costs you nothing, unlike print, where you often can't even get an ad in to the specialized journals, or radio or TV where you'd just be wasting your money with the 0.0833% MSers rate of return. (That's about six times "below" the level of "statistical noise".)

But MSBPodcast is 100% in your market, and you only pay per download of your material.

No play, no pay.

Reach the MSers who would buy your therapy, product, good or service, with-out having to waste your advertising money on anyone who is "not" interested...

So who was "Hermann Ludwig Ferdinand von Helmholtz"? [ ]

I found out about him quite recently but he's the person who determined that the a person's hearing would have to work in exactly the way it does.

---- "Fantasy in f by Chopin" by: "Linda Holzer"


Its a tube, (not a series of pipes and definitely not a truck,) a tube located in the ear. Its the main, but not the only, reason for the shapes of the inner ear.

The main shape of which is a coiled tube, like a snail, the inside of which is coated with fine hairs, called cilia, that start out sensitive to low frequency sounds at one end and tapers down to being sensitive to high frequency sounds at the other end.

Because a frequency gets shorter as it increases, the cochlea gets narrower, doan 'cha kno'.

The hairs, the cilia, that line the inside of the snail's shell, the cochlea, are sensitive to sound vibrations of one and only one frequency, they do not respond to anything else: temperature, light, shock of a frequency other than the one a cilia is tuned for by peculiar physics of its size and the size of the cochlea at that point.

The cilia are anchored, just like hair, to nerves which sends their signal to the auditory processing functions of the sensing apparatus of the brain.

Just as with the eye, some processing and encoding is done right there, (leading to certain kinds of perceptual errors,) and some is done further along on path to the brain, (leading to different kinds of perceptual errors.)

With MS, there are some further effects of "echoes, muffles, ghosts and shadows" caused by the sclera itself.

The ear is an amazing structure.

When combined as a pair, the ears are capable of directional detection so we can tell where a sound originated from.

That in and of itself is an incredible feat of pattern matching since two sounds reach the ears and it must process the sounds and encode them and compare both signals and crate further signals that tell the brain, not only that there was the sound of a twig breaking but that the bear stalking the woods is behind and to the left, and that you'd better run faster than your trekking partner or you'll end up being shit in the woods.

In normal healthy humans, the pair of organs make up a sense that is permanently "on", unlike the eyes which can close, the nose which shuts down after exposure to a particular scent or heat sensing which is too general to make any difference.

That bear is not sneaking up that easily.

The "Ouch! podcast" [ ] held their Christmas Special on December 10th, 2007 (today as I write this) and they have a special song for the "Cripples At Christmas".

The lyrics are on the show notes. (I'm keeping something for the podcast downloaders.)
