Helping The Deaf Hear
Otolaryngologists develop a
new, implantable hearing
aid. It works with a
transmitter worn behind the
ear that sends sound
vibrations from her deaf
side through the skull to
her good ear. It's called

Two Ears Are Better Than One
Unlike other acoustical
devices such as hearing
aids, which just amplify
sounds, cochlear implants
mimic what happens inside
the ear, changing sound
waves into electrical

3-D Hearing Aid
In a new study, 34
normal-hearing and 18
cochlear-implant subjects
were tested on three
speech-perception tasks
known to be notoriously
difficult for
cochlear-implant users:

Breaking Sound Barriers
A new high-tech glove
enables the translation of
sign language into written
text, facilitating
communication for the
hearing or speech impaired.
The glove senses movements

Acoustic Study Shows Safe Listening Levels
Loud, sustained sound can damage tiny hairs in the cochlea, and yet 80 percent of people listen to personal music devices at dangerous levels above background noise, a study by acousticians shows. ... > more -
Hearing And Acoustics Researcher's Mannequin Rocks To Test Safe Volume Levels
Otology research shows that many teens and adults set their headphones at volumes that can cause hearing damage. Listeners set their headphones at a preferred volume, then place them on a mannequin ... > more -
Engineers Create New Helmet to Help Troops Hear Better on Battlefield
Wearing a helmet can make it hard to figure which direction sounds -- such as gunfire -- is coming from. Soldiers in Iraq are using a new helmet, called the Advanced Combat Helmet, which is padded ... > more -
Neurologists Use New Brain Scanning Device To Better Control Seizures
Doctors are now using a new kind of brain scan called magnetoencephalography (MEG), which measures brain activity in real time. In some cases, MEG can pinpoint the source of an epileptic seizure much ... > more -
Sea Urchins' Genetics Add To Knowledge Of Cancer, Alzheimer's And Infertility
Researchers are using the sea urchins to study and understand diseases like cancer, Alzheimer's disease, Parkinson's disease and muscular dystrophy. Although they are invertebrates, the creatures ... > more -
Physiologists Investigate The Role Of Perception In Motion Sickness
The cause of motion sickness is being investigated by a researcher with a new idea: that the cause is movement, not perceptual differences. A series of motion-sickness-inducing tests shows that those ... > more -
Molecular Biologists Devise Strategy To Starve Brain Tumors
Brain tumor researchers have found that brain tumors arise from cancer stem cells living within tiny protective areas formed by blood vessels in the brain. Killing those cells is a promising ... > more -
Vision Researchers Test Theory on Visual Orientation
Vision researchers suspect that people who do not need maps to find their way may be remembering visual landmarks. To test this theory, the scientists are having volunteers navigate through a virtual ... > more -
Neurosurgeons Can Now Remove Brain Cancer Endoscopically
For more than a century, neurosurgeons have accessed the brain through the nose, but only recently did they successfully removed tumors with such minimally invasive procedures, leading to patients' ... > more -
Sociologists Weigh In On Obesity Increasing The Length Of Hospital Stays
Sociologists found a direct relationship between obesity and duration and frequency of hospital stays. Researchers found that, on average, obese persons stayed one and a half days longer than those ... > more
