Sign Language Proves Helpful For Children With Rare Speech Disorder
Using sign language with intensive speech therapy may be an effective treatment for children with a rare speech disorder called apraxia of speech, according to Penn State College of Medicine researchers. They suggest further exploration of the results of a case study showing the effectiveness of using several therapies together in cases of early diagnosis. Childhood apraxia…
New Study Could Lead To Reversal Of Hearing Loss
A team led by Harvard Medical School and Massachusetts Eye and Ear researchers may bring scientists a step closer to developing treatments that regrow the missing cells that cause hearing loss. In a new study published online December 4 in Nature Communications, scientists report a new strategy to induce cell division in the mature inner ear. With…
New Study Shows Hearing Loss Is A Widespread Issue
A new study finds widespread hearing loss among elderly Americans, with an especially high rate for those 90 and older.

Humans’ Ears Perk At Interesting Sounds Like Animals
Many animals, including dogs, cats and various species of monkeys, will move their ears to better focus their attention on a novel sound. That humans also have this capability was not known until now. A research team based in Saarland has demonstrated for the first time that we make minute, unconscious movements of our ears…
Link Discovered Between Ototoxic Drugs & Hidden Hearing Loss
The term “hidden hearing loss” refers to a form of hearing impairment in which a subject presents with normal otoacoustic emissions and audiometric thresholds but complains of hearing problems such as tinnitus or difficulty understanding speech in noise. Recent human and animal studies on aging and noise-induced hearing loss suggest that hidden hearing loss may result…

Loss Of Lip-Reading Caused By Masks Affecting Communication For Everyone
Deterioration in speech understanding when the speaker is wearing a mask mainly has visual causes. They are even more significant than the acoustic attenuation caused by the masks. According to experiments conducted by a group of hearing researchers at the medical faculty of the University of Oldenburg, the fact that we understand what a person…
