UNIVERSITY OF CENTRAL MISSOURI
Welch-Schmidt Center for Communication Disorders
Audiologic Evaluation Report
CLIENT:
Tracy Blueberry
DATE OF BIRTH: 12-1-80
CLINICIANS: Amy Arsenault and
Honora Heili
DATE OF EVALUATION: 1-29-01
HISTORY:
Tracy Blueberry, a 20 year-old female, was seen at the Welch-Schmidt Center on
January 29, 2001 for a hearing evaluation. The purpose of the evaluation was for extra
credit in Dr. Wilson's class. Tracy reported that the only time she experiences difficulty
hearing is in background noise. She denies tinnitus, vertigo, family history of hearing
loss, and ear infections. Tracy reported that she has been experiencing cold symptoms
for about two days, but she is not currently taking any medication for it.
RESULTS:
During today's evaluation, both tympanic membranes were visualized and were
unremarkable. Conventional pure tone audiometry revealed pure tone averages (PTA)
of 10 dB HL in the right ear and 5 dB HL in the left ear. An Auditory Brainstem Response
(ABR) evaluation utilizing alternating clicks (19.1 clicks per second) presented at an
intensity of 75 dB nHL revealed a wave I latency of 1.85 milliseconds (ms), wave III at
3.88 ms, and wave V at 5.60 ms, in the left ear. Due to time constraints, right ear wave
latencies were not obtained. The latencies in the left ear appear to be within normal
limits, indicating normal retrocochlear function in that ear.
IMPRESSIONS:
The results indicate Tracy is hearing within normal limits, with normal retrocochlear
function in the left ear. Further testing should be done to complete the ABR on the right
side.
RECOMMENDATIONS:
It is recommended that you:
1) Return to the clinic to complete the ABR evaluation.
2) Return to the clinic for a re-evaluation if a change in hearing is noted.
