Alligator Sound Perception Comes From Air-Filled Canals Between Their Ears
2014-03-28 09:21:20

Brett Smith for redOrbit.com - Your Universe Online For an animal without external ears, alligators have a strong sense of directional hearing and a new study published on Wednesday in the Journal of Experimental Biology has revealed that the reptiles’ refined hearing is a result of large, air-filled canals connecting two middle ears. "Mammals usually have large moveable ears, but alligators do not, so they have solved the problems of sound localization a little differently,” said...

New Hearing Implant Uses Less Power, No External Hardware

[ Watch the Video: The Sound Of Innovation For Deafness ] Lawrence LeBlond for redOrbit.com - Your Universe Online Hundreds of thousands of deaf, or near-deaf, people around the world have benefited from cochlear implants. While these devices are undoubtedly a good thing, the hardware to make them work has been somewhat of a pain. Cochlear implants typically require a small transmitter affixed to the skull with a wire dangling down to a microphone, as well as a battery pack that must...

Human Middle Ear Bones Could Provide New Evolutionary Insight

redOrbit Staff & Wire Reports - Your Universe Online The bones located in the middle of a person´s ear might be the smallest in the entire human body, but they could hold big clues regarding evolution and the development of modern-day men and women, according to research published in the latest edition of the Proceedings of the National Academy of Science (PNAS). Texas A&M University (TAMU) anthropology professor Darryl de Ruiter and colleagues examined a hominin skull from...

Researchers at King's College London have uncovered how the human ear is formed, giving clues as to why children are susceptible to infections such as glue ear. The work was funded by the UK Medical Research Council and published today in the journal Science. It is estimated that one in five children around the age of two will be affected by glue ear, a build-up of fluid in the middle ear chamber. This part of the ear contains three tiny bones that carry sound vibrations from the eardrum...

A Middle-Ear Microphone
2012-04-30 07:15:25

Device could make cochlear implants more convenient Cochlear implants have restored basic hearing to some 220,000 deaf people, yet a microphone and related electronics must be worn outside the head, raising reliability issues, preventing patients from swimming and creating social stigma. Now, a University of Utah engineer and colleagues in Ohio have developed a tiny prototype microphone that can be implanted in the middle ear to avoid such problems. The proof-of-concept device has...

A group of biologists from Denmark and the US led by Jakob Christensen-Dalsgaard, University of Southern Denmark, and Catherine Carr, University of Maryland, have shown that the turtle ear is specialized for underwater hearing. The new discovery is published in Proceedings of the Royal Society B March 21st , Special features of the turtle ear — a large, air-filled middle ear and a movable tympanic disk increase its sensitivity for underwater sound. Laser measurements of disk vibrations...

DEAR DR. DONOHUE: I dread flying. As the plane descends for landing, my right ear gives me severe pain. After we land, the pain starts to subside, and in a few hours it is mostly gone. I have seen an ear doctor, who found nothing wrong. I chew gum, drink water through a straw, yawn and swallow. I pinch my nose shut and blow. I take Sudafed two hours before departure and a nasal decongestant spray two hours before landing. Nothing helps. Can you offer any suggestions? - F.S. ANSWER: You have...

Researchers have discovered that a frog that lives near noisy springs in central China can tune its ears to different sound frequencies, much like the tuner on a radio can shift from one frequency to another. It is the only known example of an animal that can actively select what frequencies it hears, the researchers say. The findings, from a collaborative effort led by the University of Illinois and the University of California at Los Angeles, appear this week in Proceedings of the National...

A Children's Hospital of Pittsburgh study finds that prompt insertion of tympanostomy tubes (small ear tubes) does not improve developmental outcomes of children at 6 years of age as once thought. Lead investigator Jack L. Paradise, MD, pediatrician and otitis media expert at Children's and professor of Pediatrics and Otolaryngology at the University of Pittsburgh School of Medicine, and fellow researchers found that in otherwise healthy children younger than 3 years of age who have...

The ear is an organ from the auditory system that collects sounds, and also balances and enables body position. Formation and Orientation The ear can be broken down into the inner and outer ears. The outer part of the ear is the visible flap (auricle) and ear canal which collects sounds which create pressure that echoes through the middle ear. The inner ear, however, is embedded in the temporal bone. There are hollow areas of the inner ear that are filled with liquids and hair cells...

Incus Bone
2012-06-29 12:09:21

The incus (anvil) bone is an anvil-shaped small bone in the middle ear. It connects the malleus to the stapes. This bone was first described by Alessandro Achillini of Bologna. This bone also transmits sound vibrations from the malleus to the stapes. The incus bone is only found in mammals. The bone, which is derived from a reptilian upper jaw bone (the quadrate bone), embryologically derives from the first pharyngeal arch along with the rest of the bones of mastication, such as the...
