- tveyben 4y agoFascinating - especially the ‘shouting in the data center video’ (link at the end of the article…)
- thenthenthen 4y agoThanks for pointing this out, what a great video!
- lapcat 4y agoMissed opportunity to say Janet Jackson had Control.
- Gelob 4y agoWhat is the detailed technical explanation behind this?
- nineteen999 4y agohttps://en.wikipedia.org/wiki/Sympathetic_resonance https://en.wikipedia.org/wiki/Sympathetic_resonance Basically the same principle that allows an Opera singer to crack a wine glass by singing at a specific pitch very loudly.
- em-bee 4y agoeach material has natural frequencies at which they oscillate. if you produce that frequency you can get the material to shake until it breaks. that's how you can use sound to shatter glass. or why the tacoma narrows bridge collapsed. in this case the sound included a frequency that affected the laptops harddisks which are obviously sensitive to shaking
- drewtato 4y agoSeems like it would have to either stop the drive, maybe triggering shock protection, or make it read incorrect data, which could be possible if the read head's correction mechanism was resonating. If its delay was half the sound's frequency, it would try to correct in the same direction as its being pushed by the sound, causing the feedback loop for resonance.
- sohkamyung 4y agoUnfortunately, Raymond Chen repeats the disproven theory that resonance caused the collapse of the Tacoma-Narrows bridge. [1] > According to the two engineers, the failure of the bridge was related to a wind-driven amplification of the torsional oscillation that, unlike a resonance, increases monotonically with increasing wind speed.

- phendrenad2 4y ago...cool story... But I'm kinda going to wait to believe it until someone tries to reproduce it. Should be simple enough, just get some old old laptops, and play a sine wave sweep until they do something. Get on it, science clickbait youtubers!

- hulitu 4y agoSo does an ESD gun.
