KFC South Africa Lets Customers Listen To Music Using Bone Conduction
An anonymous reader writes: The end of annoying restaurant muzak may be nigh: A KFC branch in South Africa has put together a playlist of local artists for diners to enjoy — so long as they do so in silence. The in-shop broadcasts can only be heard using bone conduction as a speaker — diners put their elbows on the table and cup their ears if they want to hear the tunes.
listening to vuvuzela this way may cause minor fractures.
Tried one. Honestly, it didn't work that well.
Note for pedants: Yes. I know the ad is from 1980 and that the referenced patent expired long before now. You can silently thank me for saving you from a ranting response. And by "silently", I mean without responding. Even though posting the text could be considered silent. Unless someone has a reader. Or... Never mind. Rant away.

Turns out Freud was right.
Yes you are. There are no sound at all (or sound waves to be technical). It is basically just small vibrations that travels through your bones in your body, which your ears actually think is sound and then... magically you can hear! I guess you have to experience it to fully appreciate it. (I once was introduced to a phone for old people that used the same technology and it really works.) ps. Real sound actually also convert to small vibrations in your head before your brain interprets it, so this is just skipping the conversion step. Hope this helps :)
I appreciate that there aren't any sound waves at the table. But would the vibrations not use the cup as a sounding board? ie Vibrations --> cup --> cup base vibrates --> soundwaves? A speaker after all is just a driver vibrating a sound board of some description.
I would assume that the frequency of the vibrations wouldn't be able to change across medium, otherwise the sound would change. The magnitude however may be too small to convert to airborne sound waves loud enough to hear.
