Because of COVID-19 and broad mandates to wear face coverings, there are numerous local, state, and national conversations regarding communication access for individuals who are deaf and hard-of-hearing (DHH) in school, hospital, and public settings. Although there was an initial shortage and concerns about meeting global demands, we have witnessed, in a short period, rapid production of various types of masks and shields intended for use by either the public or health workers, including masks with clear (transparent) windows.
The major problem is that typical masks (cloth or medical) present an obvious visual barrier to those who depend on nonverbal communication cues on the face (e.g., mouth, lips, teeth, tongue, and cheeks) (Gardino et al 2008; Atcherson et al, 2017; Atcherson and Finley, 2019; Elby et al., 2020; Baltimore and Atcherson, 2020).
Indeed, both linguistic and nonverbal information are important for understanding social communication and interaction (Rieffe and Terwogt, 2000; Most and Aviner, 2009). In a timely publication concerning medical masks, Goldin et al (2020) reported acoustic degradations where medical masks act as lowpass filters and high frequencies between 2000-7000 Hz are attenuated by about 3-4 dB for simple surgical masks and up to 9-12 dB for N95 masks.
They cautioned that these reductions would prove challenging for DHH individuals when listening to speech in background noise and in reverberant (echo-like) settings—especially with advancing age and greater likelihood of hearing loss.
The National Health Service (NHS) is a conglomerate name for the publicly funded health-care system of the United Kingdom (England, Scotland, and Wales). Gentamicin is the first-choice antibiotic if a newborn develops a serious bacterial infection. According to the University of Manchester, approximately 90,000 babies a year in the United Kingdom alone are treated with…
Artificial intelligence (AI) is being used in so many facets of our existence. It is disrupting the status quo and challenging previously held beliefs and systems. From the looks of it, AI’s application in the hearing health-care arena is present and growing. AI use in hearing aids, in particular, is garnering attention outside the field….
Electrical engineer Dr. Lichauan Liu of Northern Illinois University (NIU) has designed technology to prevent hearing loss in newborns who are in the neonatal intensive care unit (NICU). NICUs are noisy places. According to Almadhoob and Ohlsson (2020), sound levels in NICUs range from 7 dB to 120 dB and often exceed the maximum acceptable…
