Three types of protocadherin-15 are known to exist in auditory sensory cells of the inner ear but it was not clear which of these protein isoforms was essential for hearing. "Our work pinpoints the CD2 isoform of protocadherin-15 as an essential component of the tip-link and reveals that the absence of protocadherin-15 CD2 in mouse hair cells results in profound deafness."

Until now, scientists have not understood what orchestrates the formation of this critical pattern of individually distinct hair cells. The researchers, however, have solved that mystery, demonstrating that two specific molecules, Bmp7 and retinoic acid, guide cells to acquire location-specific attributes. Bmp7 starts the initial patterning process, and retinoic acid regulates how the cells’ hair bundles grow to different lengths.

Earwax: A New Frontier of Human Odor Information:
 
Scientists from the Monell Center have used analytical organic chemistry to identify the presence of odor-producing chemical compounds in human earwax
 
Earwax, scientifically known as cerumen, is a mixture of secretions from specialized sweat glands with fatty materials secreted from sebaceous glands. It can have one of two physical types: a wet yellow-brown wax or a dry white wax.
 
“Odors in earwax may be able to tell us what a person has eaten and where they have been,” said Preti. “Earwax is a neglected body secretion whose potential as an information source has yet to be explored.”

A Discussion of Chronic Ear Infections:
 
Chronic ear infection is the result of an ear infection that has left a residual injury to the ear. This type of infection has been established as the cause of your ear problem. Chronic ear infection (the technical diagnosis is chronic otitis media) symptoms depend upon whether or not there is involvement of the mastoid bone and whether there is a hole in the eardrum.
 
Function of the normal ear - The ear is divided into three parts the external ear, the middle ear, and the inner ear. Each part performs an important function in the process of hearing.
 Sound waves pass through the canal of the external ear and vibrate the eardrum, which separate the external ear from the middle ear.

Hearing Technologies Could Play an Important Role in Delaying Dementia:
 
New research into understanding how the brain adapts and improves its hearing abilities through the use of hearing technologies could play an important role in the future management of dementia.
 
“Some of the best evidence for this comes from a brain imaging technique known as MEG (Magnetoencephalography) which measures tiny magnetic fields that are activated throughout our brains whenever we process information. Through MEG, researchers have been able to gain a better understanding of which areas of our brains are used to process certain kinds of information, including language. An example of one of the biggest discoveries made using brain imaging was learning that blind subjects process auditory information in both the brain’s visual and auditory cortex.”

School Hearing Tests do not Detect Noise Exposure Hearing Loss:

School hearing tests cannot effectively detect adolescent high-frequency hearing loss, which is typically caused by loud noise exposure, according to researchers at Penn State College of Medicine.

The school screenings primarily focus on low-frequency hearing loss. This is logical for young children, who are more likely to develop low-frequency hearing loss due to fluid in the ear after a bad cold or an ear infection. Adolescents, however, are more susceptible to high-frequency hearing loss, usually brought on by exposure to loud noises, but the same tests are used on adolescents and young children.

Cause of Tinnitus:
 
Tinnitus is the term for the perception of sound when no external sound is present. It is often referred to as "ringing in the ears," although some people hear hissing, roaring, whistling, chirping, or clicking.
 
The exact cause (or causes) of tinnitus is not known in every case. There are, however, several likely factors which may cause tinnitus or make existing tinnitus worse: noise-induced hearing loss, wax build-up in the ear canal, certain medications, ear or sinus infections, age-related hearing loss, ear diseases and disorders, jaw misalignment, cardiovascular disease, certain types of tumors, thyroid disorders, head and neck trauma and many others.
