Dr. Justin S. Golub, Otology, Neurotology & Skull Base Surgery Otolaryngologist and Researcher at Columbia University Irving Medical Center, has been interviewed by the New York Times in a Personal Health article published on December 30, 2019.
Dr. Golub is the lead author on a November 2019 study published on the new findings on cognitive losses linked to subclinical hearing loss. Currently, the definition on the border between normal hearing and mild hearing loss in adults is a sound level of 25 decibels — the ability to hear a whisper. In this study, Dr. Golub and the researchers demonstrated that the biggest drop in cognitive ability occurs even at the slightest level of hearing loss — a decline from zero (the sound level of a pin drop), to the “normal” level of 25 decibels. Smaller cognitive losses occurr when hearing deficits rise from 25 to 50 decibels.
For more details on this study, and how Dr. Golub discovered that hearing loss is on a continuum that starts with “perfect” hearing at zero decibels please head over to the full article in JAMA.
