What do Beethoven’s Piano Sonata No 14 in C-Sharp Minor & the
assassination of Osama Bin Laden, have in common?
Bone conduction technology was vital to both…
How does it work?
In bone conduction a transducer is used to convert sound into bone vibrations that bypass the outer ear and eardrum transmit directly to the cochlea and on to the brain.
The bone conduction system offers key safety advantages over traditional earphones, by leaving the user’s ears free so that they are not distracted from their environment. It is even possible to drive wearing them, as they comply with the legal requirement to be able to hear on the road.
In one of the earliest forms of bone conduction, Ludwig van Beethoven bit on a metal rod attached to his piano
so that he could compose and hear his work. As with so much of technologic
advancements the military have used bone conduction communication for many
years in the theatre of war. One of the most notorious missions was Operation
Neptune Spear, which killed Osama Bin Laden. Navy SEAL’s who took part in the
mission have since stated that bone conduction communication was vital during the
In normal hearing sound vibrations pass from the outer ear,
￼through the eardrum to the cochlea, which transmits them to the brain as electrical
