New Study Shows How Sounds Are Amplified In The Inner Ear, A Finding That Could Explain How Hearing Loss Can Result From Genetic Mutation Or Overdose published
Thu, 08 May 2008 05:00:00 PDT
St. Jude Children's Research Hospital investigators have found that an electrically powered amplification mechanism in the cochlea of the ear is critical to the acute hearing of humans and other mammals. The findings will enable better understanding of how hearing loss can result from malfunction of this amplification machinery due to genetic mutation or overdose of drugs such as aspirin.

British Sign Language, The Deaf And Criminal Justice published
Tue, 06 May 2008 05:00:00 PDT
Deaf people on trial were granted the right to an interpreter as early as 1725, according to Old Bailey records examined by UCL (University College London) scientists. The use of family and friends to interpret court proceedings later switched to deaf teachers and eventually written testimony, which may have disadvantaged the less educated 'deaf and dumb' at the very time that British Sign Language was emerging.

Zebrafish May Help Solve Ringing In Veterans' Ears published
Thu, 01 May 2008 02:00:00 PDT
Ernest Moore, an audiologist and cell biologist at Northwestern University, developed tinnitus -- a chronic ringing and whooshing sound in his ears -- twenty years ago after serving in the U.S. Army reserves medical corps. His hearing was damaged by the crack of too many M16 rifles and artillery explosions. He suspects his hearing also suffered from hunting opossum with rifles as a kid on his grandmother's farm in Tennessee.

Low-Frequency Hearing Linked To Shape Of The Cochlea published
Mon, 28 Apr 2008 02:00:00 PDT
Shape matters, even in hearing.Specifically, it is the shape of the cochlea - the snail-shell-shaped organ in the inner ear that converts sound waves into nerve impulses that the brain deciphers - which proves to be surprisingly important.A study published online in the Proceedings of the National Academy of Sciences establishes a direct link between the cochlea's curvature and the low-frequency hearing limit of more than a dozen different mammals.
Device That Produces Tiny Skull Vibrations A Big Help For Hearing Impaired published
Sat, 26 Apr 2008 00:00:00 PDT
Although Jim McGinn of Wheaton is completely deaf in his right ear, he still can hear from that side.A sound processor McGinn wears just behind his right ear converts sound waves into tiny vibrations that move through his skull. The vibrations are detected by his good left ear, so it sounds to McGinn like he can hear from both sides.
