Otolaryngologist Dr. Hamid Djalilian and a team of researchers tested a number of popular toys to determine which ones could damage a child’s hearing. They created a chart with each toy’s decibel level and suggest putting tape over the speaker or volume control to lessen the sound or prevent a child from being able to turn the volume up to an unsafe level.

Word Learning Better in Deaf Children Who Receive Cochlear Implants by Age 13 Months
Learning words may be facilitated by early exposure to auditory input, according to research presented by the Indiana University School of Medicine at the American Association for the Advancement of Science Annual Meeting in San Diego, Feb. 18-22.
A growing body of evidence points to the importance of early auditory input for developing language skills. Indiana University Department of Otolaryngology researchers have contributed to that evidence with several projects, including their study involving 20 deaf children (22- to 40-months-old and 12 to 18 months after cochlear implantation) and 20 normal hearing children (12- to 40-months of age) that was presented Feb. 21 at the AAAS meeting.
Children with Cochlear Implants Appear to Achieve Similar Educational and Employment Levels as Peers
Deaf children who receive cochlear implants appear more likely to fail early grades in school, but they ultimately achieve educational and employment levels similar to their normal-hearing peers, ...full story
Children with permanent hearing impairment who received hearing screening as newborns had better general and language developmental outcomes and quality of life at ages 3 to 5 years compared to newborns who received hearing screening through behavioral testing, according to a new study.
Adults born deaf react more quickly to objects at the edge of their visual field than hearing people, according to groundbreaking new research. The study, which was funded by the Royal National Institute for Deaf People (RNID), has, for the first time ever, seen scientists test how peripheral vision develops in deaf people from childhood to adulthood.
In the first known study of its kind, researchers have shown that the language we learn as children affects brain structure, as does hearing status. While research has shown that people who are deaf and hearing differ in brain anatomy, these studies have been limited to studies of individuals who are deaf and use American Sign Language (ASL) from birth. But 95 percent of the deaf population in America is born to hearing parents and use English or another spoken language as their first language, usually through lip-reading. Since both language and audition are housed in nearby locations in the brain, understanding which differences are attributed to hearing and which to language is critical in understanding the mechanisms by which experience shapes the brain.
Deaf teenagers have better reading skills if they were identified as deaf by the time they were nine months old, research has shown. The research team has been studying the development of a group of children who were identified with permanent childhood hearing impairment (PCHI) at a very early age. Follow up assessments when the children were aged eight showed those who were screened at birth had better language skills than those children who were not screened.
When people hear another person talking to them, they respond not only to what is being said -- those consonants and vowels strung together into words and sentences -- but also to other features of that speech -- the emotional tone and the speaker's gender, for instance. Now, a report provides some of the first evidence of how dogs also differentiate and process those various components of human speech.
We lost the Mother of Pediatric Audiology

Bobbing your head, tapping your heel, or clapping along with the music is a natural response for most people, but what about those who can’t keep a beat? Researchers have discovered that beat-deafness, though very rare, is a problem not simply of how people feel a pulse or move their bodies, but instead, how people synchronize with sounds they hear.
