KFC South Africa Lets Customers Listen To Music Using Bone Conduction

Posted by samzenpus on from the finger-listening-good dept.

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.

    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.
