That was lovely. Thanks for sharing.
You’re welcome @bluegroove she was something.
Poor Helen Keller… I seriously doubt she could feel notes and overtones above 200Hz with such dramatic clarity.
Science accepts an experiment if it can be repeated for verification of the results.
Place you hands on a speaker cabinet and plug your ears. Raise you hand when the female voices enter the mix.
Still, Helen Keller could write prose to conjure imagery. This is a poetic demonstration of her awe at the miracles of the physical world. Hard to prove she doesn’t visualize something but I’d imagine someone slipped her some clues what all this buzzing was about. I wonder what she would get from a Modern Vibrator? Windmills? A Ferris Wheel run amuck?
@McD i wonder, if your sensory input is so limited, maybe every little thing you can sense becomes grander?
She’s saying she can feel various instruments… anyone that looks at an oscilloscope should agree the movement of a speaker cone is extremely complex. Does a female voice have a specific appearance. Even in the frequency spectrum there’s not a lot of clues that relate to instruments in a complex mix.
I’m glad she was overjoyed at perceiving a new sense of music through her hands but she would fail a test of picking out
when the horns start playing for sure.
I new a blind person in college that could tell the color of someone's clothes by moving his fingers over them from about a half inch away. He could sense something by the quality of the reflected heat. I doubted it a little until he rightly detected my shirt was ... plaid.
I don't doubt for a minute that someone with heightened other senses could pick details out of vibrations. I also don't understand at all why you would doubt that. Sound is just vibrations. We can pick out individual instruments (vibrations) with our ears as easy as pie. Why is it hard to believe that someone with heightened sensitivity to those same vibrations via touch could do it?
Fascinating. There should be a lot of anecdotal details on this type of sense perceptions. Really interesting.
Sure.
For an early age we learn to correlate visual details and sounds. I would image Helen Keller was left to perceive her world from
touch, smell and taste there are risks associated with experiencing the world randomly. She needed to be guided as such.
So, what is an orchestra and chorus to: some mental model built primarily from braille text and the hand spelling as used by her teacher. Is possible she might percieve large scale aspect of musical signals like pitch up to maybe 1000 Hz. So, she might be able to easily detect a bass instrument playing some standard rhyming pattern that has a known name.
Kick the complexity up with a signal of a string orchestra playing harmonious tonal music. I think of music as pitch, rhythm and timbre. With a chord maybe there’s a feeling to major, minor and dominant 7th chords. That might help but just as 1 out of ~1000(?) has perfect pitch there would be degrees of capability in feeling complex music.
Anyway, like a lot of anecdotal constructs (i.e. stories) I would like to stay skeptical for anything that I give low odds of being
described accurately.
You have my interest up. Particularly, what is the basis for setting a limit to the pitch detection by touch to 1000 Hz? The entire vibration is communicated to the skin. Is there a physical limitation to what skin can conduct? Certainly you can't base the assumption on the limit of a person's ability to detect and differentiate because those limitations aren't fixed.
Let's say I put a high-pass filter at 1000Hz on a piece of audio. Are you saying that it would be impossible for anyone to differentiate a violin part from the rest?
Sorry, but I'm not sure I buy such confident assertions that humans are limited in their sensory capability. But maybe you're looking at it from pure physical constraints? Perhaps something such as physical limitations limiting eyesight to certain wavelengths?
I would think a good way for Helen to have been guided is through rhythm and rhythm instruments.
An appreciation of music must begin with the beating human heart. The rest is extrapolation.
Rhythm instruments also are pitched, so the most basic vibrations first.
Obviously some blind, deaf mutes would be naturally more gifted. But education…. How does one develop a keen appreciation of wine but through increased sensitivity (Helen could certainly train her sensitivity to subtler discriminations).
And we don not know what led up to Helen’s listening to the particular concert. She might have really been goin at it.
She might have done even better if she had put her tongue on the diaphragm!
Imagine her surprise if she sat on the radio. “More than a feeling”.
Put your hand on a loud speaker and try to mute your hearing… what can you say confidently about the audio?
Maybe have an observer correlate your guesses to the actual audio stream.
We sighted folks like to see visual images that are in some way correlated to a music track for extra impact…
very useful for lighting systems in Clubs. The lights pulse to the rhythms of the music and potential a spectrum
aspect is correlated to colors in the lights or visuals.
If you're saying that backs up your earlier assertions, that's a meaningless test for anyone who has had all senses intact from birth.
Well, anyway, I've used up my reserves of trivial argumentativeness for the day. I'm out. 😎
You are implying that a sighted person’s touch is going to meaningfully similar to a blind person’s. Whether or not Helen Keller could perceive sound with reasonable discrimination—your or my discrimination is a meaningless point of comparison. What you or I can discriminate by touching a speaker would be minimal. Someone with a differently configured sensory system who had spent a large amount of time training themselves would have a vastly different experience.
Well then the only solution would be to pluck out our eyes, break out ear drums and start practicing. Or maybe wear a mask
and plug our ears or wear a noise protecting headset. I am glad Helen had a good experience discovering the joys of music.
Huh? It just means that your proposed experiment does not shed light on the question. That doesn’t mean nothing can shed light on the question.
Nice video featuring Dame Evelyn Glennie, one of the worlds greatest classical (and other) percussionists who has been deaf since the age of 8. She often talks about feeling sounds in different parts of her body e.g. ‘ the upper drum from the waist up and the lower drum from waist down’ . There’s also a TED talk she did some time ago available on YT.

From Wikipedia:
I tried to follow her advice without a trained Physical Therapy Musicologist for guidance and got my penis stuck in a subwoofer. After the “Dark Side of the Moon” vinyl ended I was able to extricate myself. Now it’s “ribbed for her pleasure”…
Becareful how you use this new found power. You feel me?
I’m impressed that you needed a subwoofer @McD , I’m more of a tweeter man myself ☹️
It was a ported speaker so… you’ll never find a ported tweeter. I learned my lesson… use lube.
EDM is better than Pink Floyd. Your Tempo May Vary (YTMV(.
It’s a good thing Helen can’t hear this.
Interesting thread. Here's Evelyn Glennie's TedTalk, How To Truly Listen.

I have always been fascinated by the human senses. When one is compromised, others compensate. Think about the human voice. We all have nearly identical vocal cords, yet everyone has their own unique sound that we can differentiate from thousands of others. There is a man that is totally blind, but he "echolocates" by clicking his tongue. He is able to describe what he "sees" in incredibly accurate detail. He can even ride a bike in public. I just Googled him. His name is Daniel Kish. Interesting read!
I can't even imagine what Helen Keller "saw" and "heard".
I think they should make a bio-pic about Helen Keller. She was blind and deaf so new technologies should be
developed to enhance the experience of her inner life. I have submitted patents for:
Smell-o-vision
and Feel-a-round
Both were rejected for prior art:
Stink Around(tm)
Handsy(tm)
Anyway. The movie should have no music and no visuals… something like a massage, IMHO.
Hard to get financing for such a ground breaking artistic vision.
