Comments: Client in today for an evaluation of sudden onset of ear pain and sound sensitivity following prolonged exposure to noise from transformers placed in his workstation. He reported that this has made his previously intermittent tinnitus louder, caused him loudness intolerance to the point of having to use headphones all the time when outside of home, and made his previously well managed migraines much worse. He is waiting to see an ENT regarding the persisting pain in the left ear. He reported no difficulties hearing but feels that the constant vigilance to sound is causing him cognitive distraction and fatigue. WORD RECOGNITION. Presentation: Recorded / Word List: SPEECH AUDIOMETRY. Word List: dBHL % Mask | dBHL % Mask [_ SRT/SAT | Mask MCL UCL Right 50 100 Right 5 40 82 Left 50 100 Left 10 40 70 Binaural Binaural Results: L ear: normal hearing at 250-12,500 Hz, mild hearing loss at 14, 000 Hz. Small notch noted at 8000 Hz. R ear: normal hearing at 250-9000 Hz sloping to mild to moderate likely sensorineural hearing loss at 10,000-14,000 Hz. 20-30 dB asymmetry is present at 10,000-12,500 Hz with the right ear having worse thresholds. Speech Reception Thresholds (SRTs) were consistent with Pure Tone Averages (PTAs) — good test reliability. Word recognition scores in quiet were 100% in each ear when speech was presented at soft conversation level and ensuring full audibility across entire frequency range. QickSiN, a standardized assessment of sentence-level auditory speech perception in background noise, indicated 2 dB SNR loss in each ear and no differences between the ears, indicating normal hearing in noise. DPOAEs: Distortion Product Otoacoustic Emissions (DPOAEs), a test of outer hair cell function, showed responses in the right ear were present at 1-5.6 kHz and absent at 6-8 kHz while responses in the left ear were present at 1-2.8 kHz and at 5.6 kHz and absent at 3-4 kHz and at 6-8 kHz... Loudness tolerances were measured to tonal and speech stimuli and were normal in the right ear but reduced at 4-10 kHz and to running speech in the left ear, consistent with presence of hyperacusis in the left ear. Khalfa Hyperacusis Questionnaire, a self-report measure of loudness tolerance impact indicated severe level of loudness intolerance, a score of 32 out of 40. Tinnitus Handicap Inventory, a self-report measure of perceived tinnitus impact, indicated moderate tinnitus level, a score of 54 out of 100. Recommendations: 1. Medical review with an otolaryngologist regarding ongoing ear pain and sound sensitivity in the left ear. 2. Discussed caution around the use of headphones and the need to slowly reduce that. 3. Discussed sound therapy with on-ear maskers for the teatment of hyperacusis and tinnitus. Further consultation following medical review and clearance.
