New DB-OTO Results Show Sustained Improvements for Children with Profound Genetic Hearing Loss
Updated pivotal trial results show that Regeneron’s investigational gene therapy DB-OTO led to rapid, clinically meaningful, and sustained hearing improvements in nearly all children with OTOF-related profound genetic hearing loss, with some achieving normal hearing and improved speech development.

60 Percent of Childhood Hearing Loss Preventable
A new review highlights the underrecognized potential of vaccines to prevent childhood hearing loss, especially in low- and middle-income countries.
AARP Article Cites Reasons to Treat Hearing Loss
The article mentions the brain changes that studies have shown may happen when hearing loss remains untreated, potentially causing visual and sensory processing centers to access the auditory cortex, which can result in deterioration of the cortex over time.

Delta Variant of COVID-19 May Cause Hearing Loss
Hearing impairment, blood clots leading to gangrene, and “severe gastric upsets,” are being seen by doctors in India, England, and Scotland, where the B.1.617.2 delta strain is prevalent and more likely to lead to hospitalization, Bloomberg reported.

Published Review Links SARS-CoV-2 to Middle Ear Infections, Hearing Loss
The researchers concluded that “SARS‐CoV‐2 is a probable cause of middle ear infections and sensorineural hearing loss, secondary to spread of the novel virus into the middle ear and related neural structures.”

‘BMJ’ Publishes ‘First Reported UK Case’ of Sudden Hearing Loss Linked to COVID-19
The doctors describe a case of a 45-year-old man with asthma who was referred to the ear, nose, and throat department at their hospital after suddenly experiencing hearing loss in one ear while being treated for COVID-19 infection as an inpatient.

BIHIMA Survey Finds 1 in 6 UK Adults Have Hearing Loss
In a recent survey of 2,000 UK adults, commissioned by the British Irish Hearing Instrument Manufacturers Association (BIHIMA) and announced on its website, 16% of respondents self-reported suffering from hearing loss, with men being nearly twice as likely to suffer as women: 1 in 5 men reported suffering from hearing loss compared to 1 in 10 women.

Research Shows Hair Cell Damage May Be Main Cause of Age-related Hearing Loss
Researchers examined 120 inner ears collected at autopsy. They used multivariable statistical regression to compare data on the survival of hair cells, nerve fibers, and the stria vascularis with the patients’ audiograms to uncover the main predictor of the hearing loss in this aging population. They found that the degree and location of hair cell death predicted the severity and pattern of the hearing loss, while stria vascularis damage did not.

What Is “Normal Hearing” for Older Adults and Can “Normal-hearing Older Adults” Benefit from Hearing Care Intervention?
Researcher and author Larry Humes, PhD, points out that large-scale studies have identified self-reported hearing difficulties as one of the strongest predictors of hearing aid uptake and use. He says this further reinforces the need for the older consumer and the hearing care professional to quantify the severity of hearing difficulties above and beyond those captured by the pure-tone audiogram.

BBC Looks at How Loud Music Can Lead to Early Signs of Hearing Damage
The article examined a study from researchers at the University of Manchester, which suggests that although the damage observed is not enough to be diagnosed as a full-blown hearing loss, it could potentially have a cumulative effect on hearing later in life.

Researchers Look at Potential Link between Coronavirus and Hearing Loss
The authors point out that coronaviruses, in some cases, can cause peripheral neuropathy, and, ”in theory..COVID-19 could cause auditory neuropathy, a hearing disorder where the cochlea is functioning but transmission along the auditory nerve to the brain is impaired.”

USC Stem Cell Study Traces Evolution of Organ of Corti
By the time mice are born, the progenitor cells in the Organ of Corti have finished both proliferation and differentiation, and cannot regenerate if they are damaged—causing permanent hearing loss.

Age-related Hearing Loss Genes Discovered in Fruit Flies
“Our twin discoveries that fruit flies experience age-related hearing loss and that their prior auditory health is controlled by a particular set of genes, is a significant breakthrough. The fact that these genes are conserved in humans will also help to focus future clinical research in humans and thereby accelerate the discovery of novel pharmacological or gene-therapeutic strategies,” says lead-author Joerg Albert.
