Hearing Motors in the Ears ?
A new study by the University of Utah, co-written by the Chairman of the Department of Bioengineering, Dr. Richard Rabbitt, has shown that the human ear is really small, “flexoelectric engine” that accelerate to a better hearing aid for amping sounds mechanically and non-neurological.
In other words, the ears are small engines to the soup to his audience – more reason to take care of your hearing today and tomorrow.
In an interview published by the University of Utah News Center, Professor Rabbit explained: “We are reporting the discovery of a new engine nanoscale [really teeny] in the ear. The ear has a mechanical amplifier that uses electrical energy to mechanical amplification. “This function of the ear is more like a Fender amp anatomical bits long been thought that the main sound source.
The cochlea
The cochlea is a fluid-filled organ deep within the ear. Its spiral shape is coated with millions of tiny, hair-like fibers that convert sound vibrations into electrical impulses that are sent to the brain for processing.
The News of Utah said, “Prior research elsewhere indicates that the hair cells in the cochlea of the inner ear can” dance “- lengthen and contract – to help amplify the sounds.
The new study also shows really sound can be amplified by “dance” of the stereocilia, which are 50 to 300 hairs as nanotubes projecting from the top of each [cochlear] hair cells.
William Brownell, co-author of the study and professor of otolaryngology at Baylor College of Medicine in Houston, whimsically described the discovery in terms that everyone can understand.
Brownell says the new study shows how the flexoelectric effect can account for sound amplification in the cochlea. Stereocilia essentially the membranes have been shot in the tubes to the fact that it can generate an acoustic membrane [mechanics] of energy is new. Imagine listening to a soap bubble talk.
Another useful analogy is the teacher Rabbit. “It’s like the steering system of a car power,” said Rabbitt. Turn the wheel and the mechanical energy is added. Here [in the cochlea], the incoming sound is like the hand turning the wheel but to the unit, you need to add power to it. These [recently studied] hair packages add power to the sound. ”
Flexoelectrical Energy
Katie Breneman, a doctoral student of bioengineering at the University of Utah and author of the study, said that this energy can also be a part of digestion and memory formation. In other words, energy can be a source flexoelectrical recent introduction of the energy used throughout the body, not just at the tip of cochlear hair like projections.
What makes the study so interesting is the manner in which the body generates mechanical energy. Muscles and tendons flexible and relax on the basis of instructions from the brain to mechanical energy, and by itself is produced and used daily for everything from walking to deposit the food.
However, this unusual, innovative study shows that mechanical energy can also be done with delicate small body parts that only can be viewed under a microscope. The stereocilia at the end of each projection, hair floating in the cochlear fluid is invisible to the human eye
. In a recent post by Ed Yeates of KKSL NewsRadio Rabbitt professor was quoted as saying, “What we are reporting here is a new one that really has not been understood in the past. It is the stereocilia, the small tubes in the top of the cell. “Within the inner ear, the little dancing hair-like tubes actually act as electric motors.” [To amplify sound before being sent to the brain where it is processed further.]
Help for hearing loss?
Any breakthrough in the way we hear sound and process offers hope to people with hearing loss. And the research does not stop with the cochlea. Apparently flexoelectrical energy is produced throughout the body to be launched early studies examining this newly discovered physiological function.
Vroom. Vroom. His ears have motors that will help you better understand, more clearly and deeply. But further research has also indicated that damage the hair like projections that wave back and forth in the cochlear fluid is irreversible.
So, although it has reached millions of small amplifiers to boost the sound before transmission to the brain, these mechanisms remain delicate. It is important, if you’re ten years old or 100, to protect what you have.
And despite this intriguing report from the University of Utah and Baylor College of Medicine, his ears are still fragile. And the hearing is one thing that improves quality of life.
So start now by protecting hearing the noise of feet when exposed excessive. Earplugs will keep these small engines roaring in the coming years.
If you suspect your ear motors can not run as strong as before, see a hearing professional for a hearing evaluation and has unprotected stereocilia and tuned up. There is much to do to hear what they can to keep your engine running.
