Research Further Defines How Inner Ear Works

We hear sounds in part because tiny filaments inside our inner ears help convert voices, music and noises into electrical signals that are sent to our brains for processing. Now, scientists have mapped and simulated those filaments at the atomic level, a discovery that shed lights on how the inner ear works and that could […]

Three Steps to Protect Your Hearing

The Center for Disease Control (CDC) estimates 22 million workers are exposed to potentially damaging noise at work each year and the effects go far beyond lossofhearing. Exposure to excessive noise can affect more than just workers’ hearing. It can also create dangerous situations, such as an inability to hear warning signals, a decline in one’s […]

Sudden Hearing Loss Linked to COVID-19

A man in the U.K. developed sudden and permanent hearing loss in one ear after battling a severe case of COVID-19, according to a new report. His doctors are now warning others to be on the lookout for this rare but serious complication, which has been reported in a handful of COVID-19 patients around the world. Early identification […]

New Study Shows Service Industry Has Elevated Hearing Loss Risk

“Large numbers” of workers in the service industry “have an elevated risk of hearing loss and need immediate hearing conservation efforts,” NIOSH researchers say in a recent study. The researchers analyzed the results of 1.9 million audiograms of workers who were exposed to occupational noise from 2006 to 2015, including audiograms of more than 158,000 […]

Tinnitus Linked to Vitamin B12 Deficiency

Among the roles that vitamin B12 performs is keeping your blood and nerve cells healthy, as well as help in making DNA, the genetic material present in all cells. You can bet sufficient amounts of vitamin B12 in your diet. For those who follow a purely vegan diet, may struggle to fill the amount required by […]

Study of Mature Hair Cells Shows Promise in Hearing Loss Treatment

The sensory cells that line the inner ear, known as hair cells, play an important role in our sense of hearing, but are also prone to irreversible damage from stresses like excessive noise. Scientists investigating regenerative treatments for this kind of hearing loss have made an important advance, demonstrating how a single protein can determine […]

Study Shows Noise-Induced Hearing Loss Can be Blocked with Drug Compound

Inner hair cells of the cochlea (green and blue) excite auditory nerve fibers (red) by releasing glutamate, a chemical signal that helps convert sound waves into electrical signals that travel to the brain. But too much glutamate can be harmful, leading to noise-induced hearing loss. Studying mice, researchers at Washington University School of Medicine in […]

Research Shows Opioid Use Could Cause Hearing Loss

Opioid use, particularly in high doses, can cause deafness, according to Rutgers researchers. The study, published in The Journal of Medical Toxicology, reviewed records from the New Jersey Poison Control Center, based at Rutgers New Jersey Medical School, from 1999 to 2018 to determine the association between opioid use and degrees of hearing loss. Researchers identified 41 people with opioid […]

Hearing Loss Linked to Dementia Pathway

Hearing impairment was linked to neuropathological hallmarks of dementia, an autopsy study suggested. In older adults who were cognitively normal, impaired hearing was associated with tau neurofibrillary degeneration, reported Willa Brenowitz, PhD, MPH, of the University of California San Francisco (UCSF), and co-authors. And in people with dementia, hearing loss was tied to microinfarcts but […]

Bone Disease Medication May Help Reverse Hearing Loss

Preliminary findings from Harvard Medical School researchers at Massachusetts Eye and Ear may pave the way for trials to test bone density medications for hearing loss. Hearing loss caused by damaged nerves, whether from sound exposure or aging, is irreversible. There are currently no medications approved by the Food and Drug Administration (FDA) to treat […]
