What else could she have meant?
Well, since no-one is claiming that there is a real sound, I don't know why you'd need to disprove it.

I think that Skeptic Ginger misunderstood the original premise and topic and thought that people were claiming that the gif actually does have an audio track.

Her response does make sense if she had that misunderstanding.

possible explanation could be the Acoustic Reflex.

I apparently have voluntary control of the muscles involved with the acoustic reflex, for I can tense muscles in my ears and hear rumbling any time I want. Contracting muscles do generate sound.

If viewing the gif image triggers this reflex in some people, then they could actually be hearing a real sound. ...even though it is still produced inside their own heads. ;P


Quote:
Voluntary control

Contracting muscles produce vibration and sound.[3] Slow twitch fibers produce 10 to 30 contractions per second (equivalent to 10 to 30 Hz sound frequency). Fast twitch fibers produce 30 to 70 contractions per second (equivalent to 30 to 70 Hz sound frequency).[4] The vibration can be witnessed and felt by highly tensing one's muscles, as when making a firm fist. The sound can be heard by pressing a highly tensed muscle against the ear, again a firm fist is a good example. The sound is usually described as a rumbling sound. Some individuals can voluntarily produce this rumbling sound by contracting the tensor tympani muscle of the middle ear. The rumbling sound can also be heard when the neck or jaw muscles are highly tensed as when yawning deeply. This phenomenon has been known since (at least) 1884.[5]

Could it have something to do with the syncing of the thumping sound in your ears of your own heartbeat?

I would have to assume that (almost) every single person who claims they hear a sound is misinterpreting that effect.

The brain is incorrectly reacting which causes a "clench"* to occur in perhaps more than one area of the brain & sensory system. People, experiencing that effect, are for whatever reason answering "yes" to "I hear a sound".

I don't hear anything. I just see pylons jumping rope. No cross connections in my brain apparently. What a pity!

Yep, that's exactly what I experienced too.

I can do that deliberately, and the "sound" is the same, a kind of rumbling, in my case.

Like others, I'm not hearing anything, but I'm getting a weird sensation of a 'thud' when the pylon lands. The sensation isn't in my ears, it's in my temples. It's almost like my brain is expecting the thud and is clenching in anticipation and I can feel a strange tightness in my temples and a vague sensation of a thud when the pylon lands.

An in-depth article with more silent gifs which are noisy...


Why We ‘Hear’ Some Silent GIFs

Certainly, said Chris Plack, a professor of audiology at the Manchester Centre for Audiology and Deafness, who researches acoustic reflexes and auditory processing.

“Hearing,” as he defines it, does not require external noise; rather, it is “having the experience of a sound.”...

Rob Desalle, an evolutionary geneticist and curator of the Our Senses exhibit at the American Museum of Natural History, calls it a “clever illusion caused by filling in.”

“Our brains see this and they say, ‘Wow, a pylon of that size bouncing up and down should be making a noise,’” he said. So we hear one...

I wonder if this isn't related to some sort of low-level synaesthesia.

The way the image jumps as if the viewer of camera is shaken almost has me feeling/hearing it.

Oh, yeah? My brain sees something as totally unrealistic as a large-scale pylon "jumping rope" and says, "Clever bit of animation, but it ain't real." Ergo, no sound.

I'm pretty sure all contributors to the thread are aware that it's not real and thats not what is being discussd here. Anyway, well done you; what a clever boy.

I hear the "jump" instantly even though it would take a second or more to actually reach my ears.

It's clear the mechanisms at work don't understand all of physics, just some of it.

From the OP: "Do you hear the thud of the jumper?"
My response: "No."

It didn't come across quite that way, to me, at any rate. It read more like "it's not real you *********** idiots."

Can't control how you perceive things. Can barely control my own reactions. The interwebs teems with examples of perceived but untended motivations. Likewise, sarcasm, satire & irony do not play well on the internet stage.
