Air conduction canal
Sound starts its journey when captured by your outer ears, the two formations on either side of your head, travelling in air through several structures within the ear, then translated by your nervous system and your brain for use as information to live in the world.
In those with normal hearing, sound waves enter the outer ear, travel through the middle ear to the ossicles, three small bones, which transmit sound vibrations to the cochlea vestibule nerve in the inner ear.
The cochlea vestibule’s job is to convert these sounds into electrical impulses and send them along the auditory nerve to the brain.
Bone conduction canal
There is another fascinating way our body processes sound. Sound waves are also transmitted through the bones in our heads!
When our bones vibrate, sound is sent directly to the cochlea vestibule nerve in the inner ear. This sound transmission directly through our bones is similar to traveling through the eardrum and middle ear. This vibration also creates nerve impulses and connects sounds to our brains. This is called bone conduction!
In Forbrain® the amplified bone conduction and natural air conduction work with an individual’s voice to process information more clearly and understand communications better.
The audio-vocal loop or Auditory feedback loop
This is the natural process by which every individual perceives, analyzes, assimilates and continuously adjusts the information individually received and produced through sound.
To function properly, this audio-vocal loop draws on the abilities of auditory discrimination, phonological awareness and integration of rhythm that each person activates effortlessly. These skills are natural to human function and go far beyond speech. They are necessary in all learning processes.
For many reasons, this loop may be interrupted.
By optimizing the audio-vocal loop’s operating ability, Forbrain® can significantly improve :
- verbal working memory
- short-term memory
