Samuel R. Atcherson, Ph.D., CCC-A

Clinical Director of Audiology

Assistant Professor

Graduate Courses Taught:

• Anatomy and Physiology of the Auditory and Vestibular Systems
• Electrophysiologic Assessment of the Auditory System I
• Electrophysiologic Assessment of the Auditory System II
• Auditory Processing (Disorders)

Current Research:

• Completing data analyses for multiple frequency tympanograms (Y, B, and G) in young adults, and multiple frequency tympanograms in native American children from birth to 5 years of age
• Conducting a study to examine any differences in audiological testing across the duration of normal pregnancy and one-month post-partum
• Conducting a study to compare the unaided and aided spectra of Ling Sounds using probe microphone measures, and compare behavioral performance during a Ling Sound test with the aided spectra
• Conducting a study to examine the effect of noise and aging on auditory evoked brainstem responses to speech
• Conducting a study to explore the utility of auditory cortical potentials as an objective measure of small spectral contrast discrimination in normal hearing listeners

Future Research:

• Examine other ethnic or post-surgical differences in tympanograms
• Examine other auditory evoked cortical potential changes to noise and aging
• Compare auditory cortical potentials (electrophysiologic) and behavioral performance (psychophysical) to small spectral contrasts  
• Examine efferent stimulation influences on the frequency-following responses (FFR) to two-tone complexes
