UNIVERSITY OF CENTRAL MISSOURI Welch-Schmidt Center for Communication Disorders Audiologic Evaluation Report CLIENT: Andrea Raisin DATE OF BIRTH: 6-24-81 CLINICIANS: Amy Arsenault and Jaime Wigner DATE OF EVALUATION: 2-7-01 HISTORY: Andrea Raisin, a 19 year-old female, was seen at the Welch-Schmidt Center on February 7, 2001 for an Auditory Brainstem Response (ABR). The purpose of the evaluation was for extra credit in Dr. Wilson's class. Andrea reported no problems hearing. She denies tinnitus, vertigo, family history of hearing loss, and ear infections. She is not currently taking any medication. RESULTS: The Auditory Brainstem Response (ABR) evaluation utilizing alternating clicks (19.1/s) presented at an intensity of 75 dB nHL revealed repeatable wave forms for both ears. Wave I latencies were obtained at 1.63 milliseconds (ms) in the left ear and 1.67 in the right ear. Wave III latencies were obtained at 3.95 ms in the left ear and 3.78 in the right ear. Wave V latencies were obtained at 5.50 ms, bilaterally. The wave I-V interpeak latencies (IPL) were 3.88 ms for the left ear and 3.83 for the right ear. No interaural latency difference for Wave V was obtained, indicating normal retrocochlear function. IMPRESSIONS: The results indicate Andrea has normal retrocochlear function, bilaterally. RECOMMENDATIONS: It is recommended that Andrea: 1) Return to the clinic for a re-evaluation if a change in hearing is noted. _______________________________ Amy Arsenault Graduate Clinician ________________________________ Jaime Wigner Graduate Clinician _____________________________ Robert deJonge, Ph.D., CCC-A Clinical Supervisor February 7, 2001 Andrea Raisin 123 E.
