<h3>AUDIOLOGIC QUIZ CASE</h3><h3>Deborah Hayes, MA, Houston</h3> A 35-year-old woman was evaluated by the audiology service for tinnitus in the left ear. She also noticed a decrease in sensitivity in that ear of one month's duration, but still used the left ear on the telephone. Results of pure-tone audiometry are shown in Fig 1. The right ear shows relatively normal sensitivity with an apparent air-bone gap in the high frequencies. The left ear shows a mild sensorineural loss. Results of impedance audiometry are shown in Fig 2. Both right and left tympanograms are normal (type A). Acoustic reflexes are present, although slightly elevated (95 to 105 dB HL) with sound in right ear, probe in left ear. However, acoustic reflexes are absent at 110 dB HL, with sound in left ear, probe in right ear. Speech audiometry at 30 dB SL yielded phonemically balanced (PB) word and synthetic sentence identifi
