BU Engineers Send Loud and Annoying Sound Back to Where it Came
Getting an MRI can be an extremely nerve-wracking experience. In addition to the confining space, the noise can be highly annoying and anxiety provoking. Fortunately, acoustic engineers at Boston University have created a possible solution. Relying on their mathematical prowess and 3D printing technology, Reza Ghaffarivardavagh and Xin Zhang developed an open, ring-like structure that…

Researchers Restore Hearing in Deaf Mice Using Gene Therapy
PARIS, FRANCE — Researchers have announced the successful restoration of hearing in an adult mouse model of DFNB9 deafness — one of the most frequent cases of congenital, genetic deafness. Individuals with DFNB9 deafness are profoundly deaf due to a deficiency in the gene coding for otoferlin, a protein which is essential for transmitting sound…

MIT Researchers Use Laser to Transmit Sound into People’s Ears
Laser technology has been used for several decades and has a wide of applications, including bar code scanning, Lasix eye surgery, and industrial cutting and engraving. Now, laser might be used in hearing technology. Researchers from the Massachusetts Institute of Technology’s Lincoln Laboratory report using two different laser-based methods to transmit various tones, music and…

Hearing Loss, Dementia and Cargo Cult Science
The preeminent American physicist, Richard Feynman, coined the term “cargo cult science” to describe practices that on the surface appear scientific, but upon closer scrutiny lack any of the precepts of the scientific method. A January 25th JAMA viewpoint article raises the red flag on the rise of pseudoscience in the care of older adults…

New Research Uncovers Function of Inner Ear Involved in Speech Processing
SOMERSET, NEW JERSEY – Research recently published in Science Communications, by an international team of researchers from Oticon and Interacoustics, has revealed a previously undiscovered function in the inner ear that detects the acoustic details in speech before it is converted into information for the brain. The findings may help professionals learn more about individual hearing…

New Gene Discovery Could Lead to Hearing Loss Prevention Drug
According to a recent report in an October issue of The Journal of Clinical Investigation, a team of UC San Francisco researchers have discovered a gene that plays an essential role in noise-induced deafness. By administering an experimental chemical — identified in a separate UCSF lab in 2013 — that acts on the pathway linking…

Longitudinal Study Shows Relationship Between Cognition, Untreated Hearing Loss and Social Isolation
Readers may recall a July 2017 Lancet study which estimated 35% of the risk factors associated with dementia was modifiable, and that the most prominent modifiable risk factor was hearing loss, which contributed 9% toward the acceleration or possible onset of dementia. A study, published in JAMA Otolaryngology last week, builds on this eye-opening data.…

Two New Studies Show the Value of Both Audiologist-driven and Patient-driven Fitting Approaches
Famed Nobel Laureate, physicist, Richard Feynman, once said, “The statements of science are not what is true or not true, but statements of what is known with different degrees of certainty.” Two recently published papers, each examining a different angle of the hearing aid fitting process, demonstrate how Feynman’s aphorism accurately describes some of the…
