Eighty percent of Americans over 50 say their primary care doctor hasnt asked about their hearing in the past two years, and nearly as many - 77% -- havent had their hearing checked by a professional in that same time, according to a new national poll report.

They can hear well up to about forty years old, but then suddenly deafness strikes people with DFNA9. The cells of the inner ear can no longer reverse the damage caused by a genetic defect in their DNA. Researchers at Radboud university medical center have now developed a genetic patch for this type of hereditary deafness, with which they can eliminate the problems in the hearing cells. Further research in animals and humans is needed.

Neandertals -- the closest ancestor to modern humans -- possessed the ability to perceive and produce human speech, according to a new study published by an international multidisciplinary team of researchers including Binghamton University anthropology professor Rolf Quam and graduate student Alex Velez.

 E-Mail In the first few months of their lives, babies cry, babble, gurgle and make a variety of other peculiar sounds. It can be difficult to imagine that they are actually laying the foundations for later speech with these utterances. However, there is a determining element that proves that even their cries can be assigned to a particular language: the speech melody - or, more accurately: prosody. "Every language is characterised by specific musical elements, which we call prosody," says Kat...

According to a research conducted by JCDR, at least 9 out of 10 adults suffer from low health literacy in India. Health literacy is a vital aspect of any nations growth - be it developed, underdeveloped or a developing nation. A team of researchers lead by Ruban Nersisson, at the School of Electrical Engineering,

 E-Mail The ability to speak is one of the essential characteristics that distinguishes humans from other animals. Many people would probably intuitively equate speech and language. However, cognitive science research on sign languages since the 1960s paints a different picture: Today it is clear, sign languages are fully autonomous languages and have a complex organization on several linguistic levels such as grammar and meaning. Previous studies on the processing of sign language in the huma...

This study examined how lockdowns during the COVID-19 pandemic changed the spoken communication environments of children with cochlear implants by comparing the sounds they were exposed to before and during the resulting closures of schools and nonessential businesses.

RIVERSIDE, Calif. -- Astrocytes -- star-shaped cells in the brain that are actively involved in brain function -- may play an important role in stuttering, a study led by a University of California, Riverside, expert on stuttering has found. "Our study suggests that treatment with the medication risperidone leads to increased activity of the striatum in persons who stutter," said Dr. Gerald A. Maguire, professor and chair of the Department of Psychiatry and Neuro...

FOR IMMEDIATE RELEASE Scientists have yet to answer the age-old question of whether or how sound shapes the minds of fetuses in the womb, and expectant mothers often wonder about the benefits of such activities as playing music during pregnancy. Now, in experiments in newborn mice, scientists at Johns Hopkins report that sounds appear to change "wiring" patterns in areas of the brain that process sound earlier than scientists assumed and even before the ear canal opens. The current experiments ...
