Why Some People Can Hear Silent GIF (bbc.com)

An anonymous reader shares a BBC report: Some people claim they can hear a thudding sound when the pylon hits the ground and the picture vibrates. Last weekend, Dr Lisa DeBruine from the Institute of Neuroscience & Psychology at the University of Glasgow posted it on Twitter, asking her followers to describe whether they experienced any auditory sensations while watching it. One person who suffers from ringing ears replied: "I hear a vibrating thudding sound, and it also cuts out my tinnitus during the camera shake." Others offered explanations as to why. While another suggested it may have something to do with correlated neuronal activity: "The brain is 'expecting/predicting' what is coming visually and then fires a version of what it expects across the relevant senses. Also explains why some might 'feel' a physical shake."

When I was fresh out of college with about 2 weeks experience in coding, I solved an issue with our companies $200k F5 firewall that had our entire senior admin team and the F5 on site support. They were about 2 days into trying to solve a problem where the customer was periodically unable to connect to our web service. The multi-million dollar contract was hanging on by a thread with a furious customer. Based on nothing more than the original email from the customer, in under 10 minutes I was able to create a hypothesis, and 20 minutes later, my co-worker created a test to reproduce the issue. I didn't even try to run anything. I just thought about the problem. I knew almost nothing about HTTPS and absolutely nothing about how the F5 did reverse HTTPS proxying, and absolutely nothing about the web service behind the F5. Turned out it was a miss-match in configuration between HTTPS cookie caching expiration and HTTPS session expiration.

      As for the "packet" thing. I was helping someone on a forum that was experiencing intermittent bursty packetloss on their internal network with a microservice architecture. Again, this was early in my programming career and had zero experience with microservices and pretty much anything else for that matter. They had by trying to track this issue down for nearly a year, hiring consulting services to investigate, lots of packet-sniffing, special switches. After a day of thinking on the problem, I had an image in my head that involved their software, OS, NICs, and switches that I kept rotating. As I was messing around in my head, I suddenly felt a prick on my finger whenever I rotated the image. I finally narrowed in on the part that resulted in this sensation. Then I had to reflect for a few hours on what that part of the image meant. I eventually figured out it represented a large number of microservices all making requests over established TCP connections, and all of these servers hitting a common upstream bottleneck where the buffer was not large enough on the switch. I posted on the forum, asking if they had a situation where a single API call had a large number of dependencies on many other microservices, and if these services were on servers that had a shared upstream bottleneck. Yes, my guess was correct. I told them to try disabling HTTP connection pooling. The problem went away. Eventually they had to install a switch with larger buffers. The issue was all of these microservices were effectively in sync with each other, and when they all attempted to transmit data over a common bottleneck, their accumulative TCP window was too large and the burst of packets resulted in the 1Gb port dropping packets, even if the average bandwidth was very low.

  18. Tinnitis cutting out is a clue. by Ungrounded+Lightning · · Score: 1

    The report of the Tinnitis cutting out is a clue.

    Tinnitis - ringing in the ears - sometimes (always?) includes a malfunction of a feedback mechanism where an actuator is shaking the ear's innards. You can pick up the "ringing in the ears" with a microphone stuck into the ear.

    Perhaps the brain is sending the expectation of a loud sound either to that actuator, or to the one that tightens up the eardrum (reducing the sensitivity) to protect the ear's mechanism from loud noises. Either would produce an actual physical stimulus to the ear's sensors, and either might be detectable by an in-the-ear-canal microphone.

  31. Solves a childhood mystery for me. by H-S.he29 · · Score: 2

    Wow. This is my first lead to figuring out something that "bothered" me since I was a kid -- long ago I learned to produce a sort of "rumbling" sound inside my head, by intentionally tensing some muscles. It is really hard to explain as I can't even identify those muscles myself, but I first noticed it when I was doing some silly things with my eyes, like trying to "shake the picture really fast".

    I could not search for something I could not describe and I eventually forgot about it. Until I saw this GIF. At first I did not really hear anything, but I definitely felt something like a sound. And then it hit me -- it was a very short burst of the same "rumbling" sound I knew so well.

    I took to Google again and found a perfect explanation within like 30 seconds.

    So, as far as I can tell, the sound people are hearing is definitely not a "filler" produced by the brain. It's the sound of the tensor timpani muscle contracting in anticipation of a loud sound (that never comes).

    It's hard to explain. It's almost a "thud" feeling and almost a sound but not quite "there", and I cannot explain what "there" is. It's kind of as if part of my mind is running a simulation on the side of what it would be like to actually be there, and in that simulation there is the sound and sensation of a thud, but the rest of the my brain is merely observing the simulation rather than fully buying into it.

    I suspect this is primal in that if for example you saw an actual bear growling at you and showing its teeth, your head runs a quick simulation of the bear biting & crunching into your skull, and the simulation has just enough realness to trigger a fight-or-flight response/instinct.

    Brains are largely a prediction engine, and to react properly to predictions, they have to trigger senses and patterns of senses close to the real thing. Otherwise, our experience won't be applied right to devise a proper reaction.

      Magnetostriction. Your monitor, your old Amstrad CPC etc. usually will have some small switch mode DC-DC converters inside them, which will have at least one inductor. The frequency or at least duty cycle of the switching in the DC-DC converter will change as the load it is powering changes - for instance, as a CPU starts processing more complex instructions, or a circuit starts transitioning states frequently (e.g. to change pixel colours) - CMOS circuits draw more power when they go from one state to another.

      The inductors often "sing" quietly (magnetostriction) and the frequency and/or timbre will change as the load changes. You can often really hear it if you put the device up against your ear.
