SAY IT ISN’T SO!!! Due to restrictive interstate gaming regulations, we regret that we will be unable to offer the 50/50 split or silent auction fundraisers during the upcoming 2022 NHCA virtual conference. We know how much all of you enjoy both activities, so we look forward to continuing these traditions at our next face-to-face conference in 2023. In the interim, we of course will gladly accept your monetary donations. Simply visit our website and click “Donate Now.” You may also designate the NHCA Scholarship Foundation as your favorite charitable organization on Amazon.com. Amazon Smile will donate to the Foundation 0.5% percent of your purchases at no cost to you.

DoD Funding Opportunity – Hearing

Protection Fit Testing System

Posted: January 12, 2022

The Department of Defense (DoD) Health Agency has released a Small Business Innovative Research announcement for "Scalable Multi-person Hearing Protection Device Fit-testing System." The objective is to develop a system that can simultaneously fit-test multiple people with their personal hearing protection devices (HPDs). The system should be usable in clinical and non-clinical settings to quickly test the fit of HPDs from various manufacturers. Grant applications are due February 10, 2022. For details, go to https://www.dodsbirsttr.mil/topics-app/ (Search for "Hearing Protection" or "Fit-testing" in the Filter By box)

Hearing Research - Current Insights

Posted: January 12, 2022

  • Researchers at The Center for the Promotion of Health in the New England Workplace, a NIOSH Center of Excellence for Total Worker Health®, recently designed a hearing conservation intervention, HearWell, based on their new Healthy Workplace Participatory Program. HearWell uses worker participation in the form of design teams as part of a Total Worker Health approach to workplace safety and health. The goals of this intervention were to increase hearing protection device use and improve the so-called “hearing climate,” which includes supervisor and coworker support for using the devices. Results of a pilot program with transportation highway workers indicate that HearWell shows promising results for improving hearing protection use in the workplace.

  • Researchers at four universities collaborated to review the relationship between noise exposure, selected health conditions, and well-being among nurses. They analyzed data obtained from surveys of over 3800 nurses regarding noise exposure, health conditions, stress, professional quality of life, and workplace support. They found that nurses who reported high noise exposure in the workplace also reported more health conditions, higher stress and burnout scores, and lower supportive environments. High noise exposure was significantly associated with lower professional quality of life.

  • Speech-in-noise tests and suprathreshold auditory evoked potentials are considered potentially promising biomarkers for diagnosing cochlear synaptopathy in humans. Ghent University studied a small group of young adults to determine if these biomarkers changed after a discrete recreational noise exposure event, a 5-day music festival. They found individual variability in pre-festival test results, but did not observe significant changes related to noise exposure from the recreational event. Additional study is recommended.

  • In an NIH-funded animal study (chinchillas), researchers attempted to determine effective preloading timepoints for D-methionine (D-met) for protection against steady state and impulse noise. Data were collected on ABR thresholds and cochlear and serum antioxidant measures. Results indicated that the optimal D-met preloading start time window is earlier for steady state (3.5–2.5 days) than impulse noise (3–2 days). For steady state and impulse noise exposure, significant threshold shift protection occurred at all test frequencies for these start times.

Sound Postcard

Posted: January 12, 2022

Ever heard of the Music Modernization Act? Passed in 2018, this law changed copyright protection for recorded sound. As of January 1, audio recordings made prior to 1923 entered the public domain, similar to existing copyright expiration timeframes for film, literature, and photographs. This means that hundreds of thousands of early sound recordings have recently become available to interested historians, sound archivists and musicians. Check out events such as A Celebration of Sound – Public Domain Day on January 20, 2022 or the World According To Sound. Happy listening!
