Sounds that you can't hear can hurt your ears. There is nothing new there and creating such a device would be pretty easy.

- Chardok 9y agoI did not know that! It looks like anything greater than 120dB could be entirely inaudible and can lead to hearing loss. https://en.wikipedia.org/wiki/Ultrasound#Safety https://en.wikipedia.org/wiki/Ultrasound#Safety
- jsjohnst 9y agoYou are misquoting the article linked, greater than 120db is definitely audible depending on the frequency and the listener. Even at the frequencies they mention (25k being the highest), those are still audible to many humans (myself included).
- AstralStorm 9y agoEven when not audible this high air pressure would be painful.
- gmarx 9y agoI wouldn't be 100% certain but yes, it seems unlikely that sound could damage the part of the ear that is stimulated by the given frequency without you hearing it. It's kind of a weird story. A bunch of people lose their hearing and the first and only thought is mystery weapon? There are a lot of things, including many common medications and infections that can cause hearing loss. I wonder if they know more or less than reported
