Hearing Research – Current Insights

Posted: February 2, 2022

  • Noise was one of the first hazards NIOSH addressed when the Institute was established in 1971. A dedicated Noise Section was established to conduct field studies of noise exposure, design engineering controls, test hearing protection devices, evaluate the effectiveness of hearing loss prevention programs, develop standards, and advise government and non-government entities on occupational noise-related policy. As NIOSH celebrates its 50th anniversary, the NIOSH Hearing Loss Prevention Research Program looks back over 50 years of research and recommendations for preventing work-related hearing loss.

  • To address the burden of global hearing loss, WHO has identified a compendium of key evidence-based ear and hearing care interventions to be included within a country’s universal health coverage packages. To assess the cost-effectiveness of these interventions and their budgetary effect for countries, WHO analyzed the investment required to scale up services from baseline to recommended levels, and the return to society for every US dollar invested in the interventions.

  • The prevalence of hearing loss in the Department of Defense continues to decrease for service members and civilians enrolled in hearing conservation programs, according to a recent report from the Defense Health Agency Hearing Center of Excellence. According to Dr. Theresa Schulz, HCE prevention section chief, data show the number of hearing-impaired service members fell from 18% in 2013 to 15% in 2020. Report findings also reveal the percent of noise-exposed civilians with hearing impairment continues to show a gradual decrease from about 46% in 2013 to 39% in fiscal year 2020.

Sound Postcard

Posted February 2, 2022

This month we turn our ear to the (very) distant past. Archeologists have long been fascinated by England’s famous Stonehenge Circle and similar stone structures – how they were built, how they were used, their deeper meaning and significance to ancient societies. Now scientists are analyzing the acoustics of these structures to better understand what early cultures would have experienced. Acoustic engineers at the University of Salford built a complete 1:12 scale model of Stonehenge using computer-aided design techniques and then tested the model in a sound laboratory, similar to modeling tests of concert halls and opera houses. Their studies suggested that four thousand years ago, the strong reverberations of musical instruments such as drums and horns would have been amplified when played in the monument’s inner sanctum, but these sounds would have been less audible to anyone outside the circle.
