Hearing Loss In The Dental Office: The Effects Of High Speed Dental Drills On Dentists' Hearing, Krisztina Johnson, Jacek Smurzynski, Saravanan Elangovan, Marc Fagelson
Hearing Loss In The Dental Office: The Effects Of High Speed Dental Drills On Dentists' Hearing, Krisztina Johnson, Jacek Smurzynski, Saravanan Elangovan, Marc Fagelson
Marc A. Fagelson
Hearing test results of 23 dentists obtained before and after working hours are compared to determine if dentists experience any temporary hearing loss. The aim of the project is to determine whether dental drills cause hearing loss and to document the consequences of the loss. Hearing evaluations include pure-tone audiometry, middle-ear testing, and measurements of otoacoustic emissions. The results are expected to convince dentists of the danger of noise exposure and the need for hearing protection
Musical Training Influences Auditory Temporal Processing, Saravanan Elangovan, Nicole Payne, Jacek Smurzynski, Marc A. Fagelson
Musical Training Influences Auditory Temporal Processing, Saravanan Elangovan, Nicole Payne, Jacek Smurzynski, Marc A. Fagelson
Marc A. Fagelson
Background: A link between musical expertise and auditory temporal processing abilities was examined.
Material and methods: Trained musicians (n=13) and non-musicians (n=12) were tested on speech tasks (phonetic identification, speech recognition in noise) and non-speech tasks (temporal gap detection).
Results: Results indicated musicians had shorter between-channel gap detection thresholds and sharper phonetic identification functions, suggesting that perceptual reorganization following musical training assists basic temporal auditory processes.
Conclusions: In general, our results provide a conceptual advance in understanding how musical training influences speech processing, an ability which, when impaired, can affect speech and reading competency.
Military Trauma And Its Influence On Loudness Perception, Marc A. Fagelson
Military Trauma And Its Influence On Loudness Perception, Marc A. Fagelson
Marc A. Fagelson
Excerpt: It is often the case that veterans who experience hyperacusis have hearing loss and tinnitus; what sets the patient with PTSD apart is an increased likelihood that will rate sound tolerance problems as more severe than tinnitus and hearing loss.
Tinnitus And Trauma, Marc A. Fagelson
Tinnitus And Trauma, Marc A. Fagelson
Marc A. Fagelson
Trauma-provoked tinnitus challenges patients and clinicians. Effects of trauma may exacerbate tinnitus, and patients with both tinnitus and posttraumatic stress disorder rate distress levels as higher than patients who experience only one or the other. This presentation will highlight links between tinnitus and trauma histories relevant to clinical audiologists.
Auditory Filters Measured At Neighboring Center Frequencies, Marc A. Fagelson, C. A. Champlin
Auditory Filters Measured At Neighboring Center Frequencies, Marc A. Fagelson, C. A. Champlin
Marc A. Fagelson
Auditory filters were derived in 20 normal-hearing human listeners at center frequencies (CFs) of 913, 1095, 3651, and 4382 Hz using the roex (p,r) method. Comparisons were made between slopes of the filters' skirts at the neighboring CFs with filter output levels of 45 and 70 dB. The same comparisons were made with regard to filter equivalent rectangular bandwidth (ERB). In the 1000-Hz region, the low-frequency slopes (Pl) of filters centered at 913 and 1095 Hz were significantly correlated at both stimulus levels, while the high-frequency slopes (Pu) were similar only at the high test level. In the 4000-Hz region, …
Implementing Psychological Methods In The Management Of Trauma-Associated Tinnitus, Marc A. Fagelson
Implementing Psychological Methods In The Management Of Trauma-Associated Tinnitus, Marc A. Fagelson
Marc A. Fagelson
Dr. Fagelson, (Professor Audiology, ETSU) will discuss the unusual challenges facing patients and providers when tinnitus severity is linked to traumatic exposure. Interactions between neural mechanisms associated with tinnitus, posttraumatic stress-disorder (PTSD), and traumatic memory will be reviewed with particular attention to the way and degree to which such interactions affect tinnitus and disorders of sound tolerance. Conference attendees will be provided theoretical models of emotional memory consolidation that underscore trauma‘s durable effects on a patient‘s emotional state, reaction to the tinnitus signal, and to potentially-triggering environmental sounds. The putative benefits of tinnitus counseling will be presented in the context …

Audiology Services At Remote Area Medical Expeditions In Southern Appalachia, Marc A. Fagelson
Marc A. Fagelson
This presentation summarizes the preparation for, and execution of, audiology series provided by East Tennessee State University's Audiology, Program at Remote Area Medical (RAM) expeditiors in the Southern Appalachian region. In 2010 and 2012, ETSU audiology faculty and students evaluatd 281 patients and subsequently fit 178 hearing aids.
