Sound is vibration! When it travels through the air to the eardrum, we use the term 𝗮𝗶𝗿 𝗰𝗼𝗻𝗱𝘂𝗰𝘁𝗶𝗼𝗻. Sound travels even better through the bones of the body: this is called 𝗯𝗼𝗻𝗲 𝗰𝗼𝗻𝗱𝘂𝗰𝘁𝗶𝗼𝗻. Cover your ears and speak normally. You hear your voice perfectly clear because it travels mainly through the bones of the skull. Speak louder and you can feel your whole body vibrate.
During the Tomatis® listening sessions, music and voice are transmitted through special headphones equipped with both air and bone conduction. The sound reaches the auditory canal via the eardrum and directly to the cochlea through vibrations from the top of the skull.
Dr Tomatis discovered a natural way to improve 𝗹𝗶𝘀𝘁𝗲𝗻𝗶𝗻𝗴 (auditory processing) by first transmitting the sound via bone conduction followed by air conduction a fraction of a second later. This dual transmission of the sound at two different times educates the brain to correctly analyse the message and to pay attention.
The first bone conduction technology was implemented on Tomatis® headsets more than 40 years ago. Today, bone conduction technology is used in the medical industry (cochlear implants), military (ground intervention transmission helmets) and leisure (gaming, Google Glass).
