AAO Video Series Addresses Implicit Bias

Posted: November 3, 2021

The American Academy of Otolaryngology recently launched a series of short training videos to help medical professionals avoid implicit bias in their practice. There are several vignettes exploring the ten most common types of implicit biases in healthcare, including age, gender, ethnicity, religion and more. Although the videos are geared toward otolaryngologists, hearing care professionals may find them beneficial. To view, click here.

 

In memory – Dr. Richard Price

Posted: November 3, 2021

It is with sadness that we note the passing of G. Richard “Dick” Price on 5-22-21. Dick was raised in Delaware and received a Ph.D. in Physiological Psychology from Princeton University. He worked 40 years as a research psychologist at the Behavioral Research and Engineering Directorate for the U.S. Army. Dick’s primary research focus was impulse noise. One of his best-known contributions was work on development of the Auditory Hazard Assessment Algorithm for Humans (AHAAH), a model for predicting risks of exposure to impulse noise. He was a frequent contributor to NHCA conferences and is the 2007 recipient of NHCA’s Outstanding Hearing Conservationist Award.

 

News from Your NHCA Executive Council (EC)

Posted: November 3, 2021

Periodically, your NHCA EC will be sharing updates through E-News. We hope you enjoy.

  • An Auditory Situational Awareness task force was formed, chaired by Stan Phillips, to draft an NHCA position paper on auditory situational awareness.
  • Volunteers are needed to serve as NHCA alternate voting representatives on the American National Standards Institute (ANSI) S3 (Bioacoustics) and ANSI S12 (Noise) sub-committees. If interested, please contact Gayla Poling at [email protected].
  • The 2022 International Hearing Protector Fit-testing Symposium is still in the works. Volunteers internal and external to NHCA are needed. If interested, please email Laurie Wells at [email protected].
 

Hearing Research – Current Insights

 Posted: November 3, 2021

  • NIOSH researchers recently completed a study of hearing protection device (HPD) non-use among noise-exposed workers in 2007 and 2014. It was found that there was no significant change in non-use between 2007 and 2014. HPD non-use varied widely by industry and occupation, and 53% of noise-exposed workers did not wear their HPDs regularly.

  • This study assessed the association of self-reported noise exposure and audiograms collected from NHANES, with 10 algorithms proposed to quantify noise-induced hearing loss (NIHL). A new algorithm, the Adjusted Notch Depth (AND), was marginally better than other algorithms in identifying those with self-reported noise exposure. However, the researchers concluded that their findings do not support the use of pure tone thresholds for identifying NIHL alone.

  • This tutorial provides an overview of the field of epidemiology with special application to audiology and the study of hearing loss. The most common epidemiologic study designs, measures of frequency, and measures of association are highlighted and discussed.

  • Who knew acoustics had so many applications? Check out this cool article from Stanford Medicine to learn how researchers are using sound in novel ways, such as mapping the whereabouts of mosquitos, creating Faraday waves to align heart tissues for improved diagnosis and treatment, creating a brain stethoscope to listen to the brain and recognize brain seizures, and implantable devices powered and recharged by sound.
