There, three bones hinged together relay
eardrum vibrations to the inner ear, which is separated by more membranous tissue.
The team, which included Christopher Shera at the University of Southern California and David W. Smith of the University of Florida, is still investigating how
these eardrum vibrations impact what we hear, and what role they may play in hearing disorders.
Surprisingly,
these eardrum vibrations start slightly before the eyes move, indicating that motion in the ears and the eyes are controlled by the same motor commands deep within the brain.
In future experiments, they will look at whether up and down eye movements also cause unique signatures in
eardrum vibrations.
Not exact matches
GET IT THROUGH YOUR THICK SKULL: Bone conduction devices already on the market, such as some Bluetooth headsets, work on a similar principle; the
vibrations travel only through bone, however, so they bypass the soft tissue of the
eardrum.
A trio of small bones linked to the
eardrum picks up the
vibrations and sends them to the inner ear's fluid - filled cochlea.
Delicate bones in the middle ear, known as ossicles, convey the
vibrations of the
eardrum to the cochlea, the small, spiral chamber in the inner ear that converts acoustic signals to electrical.
Incoming sound waves make the
eardrum vibrate, and the
eardrum delivers these
vibrations using the ossicles to the inner ear where hair cells translate them into electric signals sent to the brain.
At the receiving end, the outer ears collect the waves» energy, causing
vibrations in the tympanic membrane — the
eardrum.
Each participant also wore small microphones in their ear canals that were sensitive enough to pick up the slight
vibrations created when the
eardrum sways back and forth.
The researchers found that keeping the head still but shifting the eyes to one side or the other sparks
vibrations in the
eardrums, even in the absence of any sounds.
The emphasis on
vibration connects the throbbing drumhead to the pulsating speaker cone, the quivering
eardrum, neuronal bursts, the beating heart, and the oscillations of light, sound, and the other electromagnetic waves that engulf us.
Seems that when a sound is emitted the
vibrations of the air don't rest when they've hit our
eardrums but continue radiating out, causing, well, most everything to oscillate in sympathy.
When a sound travels into the inner ear, from the pinna (outer ear), the waves are channeled to the
eardrum (also called the tympanic membrane) which signals the inner ear bones through
vibration.
It's the exact same technology we used on the Kyocera Torque, called Smart Sonic Receiver, which actually causes small
vibrations in your
eardrum that are picked up by your body as sounds.
