Dr. Arehart's primary area of expertise is audiology and hearing science. Her research focuses on understanding auditory perception and the impact hearing loss has on listening in complex auditory environments. A primary research project focuses on the effects of age, hearing loss and cognitive abilities on hearing aid outcomes. Other research projects include the effects of hearing loss on pitch perception, signal-processing algorithms to improve speech-in-noise perception by persons with hearing loss, perception of sound quality, and the interactive effects of aging and hearing loss on speech perception. These research projects include interdisciplinary collaboration with colleagues in engineering/psychology/cognitive science. Dr. Arehart teaches undergraduate & graduate courses in speech and hearing science and audiology and leads outreach workshops for K-12 teachers on teaching children about sound, hearing and hearing health. She is a certified clinical audiologist.

SLHS 3106 - Hearing Science
Spring 2018 / Fall 2018 / Spring 2019 / Fall 2019 / Spring 2020 / Fall 2020 / Spring 2021 / Fall 2021
Focuses on the three main aspects of the hearing process: sounds in the environment (physical acoustics), sounds encoded within the auditory system (physiological acoustics) and perception of sound (psychological acoustics).
SLHS 6006 - Advanced Hearing Science
Fall 2018 / Fall 2019 / Fall 2020 / Fall 2021
Provides advanced study in hearing science, including physical, physiological, and psychological acoustics of both normal and impaired auditory systems. Department enforced prerequisite: graduate standing in SLHS; undergraduate course work in biology or anatomy.
SLHS 6670 - Adult Aural Rehabilitation
Spring 2018 / Spring 2020
The course will address research and evidence-based practice regarding hearing loss in adults across the age span. Topics will include aural rehabilitation, co-morbidities associated with hearing loss (e.g., cognition and dementia; mental health; sensory-perceptual-motor skills; other health/medical conditions), and impacts of hearing loss on functioning, disability, health, and health services. Recommended prerequisites: SLHS 7418 and SLHS 7540.
SLHS 7450 - Audiology Capstone Project
Summer 2018 / Fall 2018 / Spring 2019 / Fall 2019 / Fall 2020 / Spring 2021 / Fall 2021
Provides an individualized project for AUD, completed prior to initiation of final clinical year. May be in the form of research-based investigation, an evidence-based position paper, a clinical protocol based on peer-reviewed literature, a grant proposal, or another format approved by AUD committee. Project requires approved proposal by AUD committee andfocused study supervised by capstone advisor.
