MP3 Players: How Loud Is Too Loud?
Loud, sustained sound can
damage tiny hairs in the
cochlea, and yet 80 percent
of people listen to personal
music devices at dangerous

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

Dangerous Decibels
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 equipped with an

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 -
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 -
Electrical And Computer Engineers Develop Computer Game For Visually Impaired And Sighted Players
Computer engineers developed a new computer game, called AudiOdyssey, for visually impaired persons. The game primarily focuses on sounds and rhythms, which visually impaired and sighted players can ... > more -
Radiologists Use Light To Scan The Inner Workings Of The Brain
Radiologists have developed a new device to understand brain activity. It is a collection of fiber optic cables attached to a flexible cap placed atop the head. The cables send near-infrared light ... > more -
Acousticians Improve Sound Quality of Cochlear Implants
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: speech recognition with a ... > more -

GPS Navigation System Gives Acoustical Warnings
Human factors psychologists have teamed up with computer scientists to develop technology that can do the job of a seeing-eye dog -- help the blind walk around safely and without getting lost. The ... > more -
Cognitive Neuroscientists Use Sound Training To Help Dyslexic Children Read
Cognitive neuroscientists monitoring brain activity with fMRI found that children with dyslexia are often unable to process the fast-changing sounds used in spoken language. Sound training dedicated ... > more -
Pediatric Neurologists Use MRI to Understand How Strokes Impair Verbal Abilities
Children who have speech-impairing strokes often learn to talk again, while adult stroke victims can lose their verbal abilities for good. By giving reading and verbal tests inside the MRI, ... > more
