Hearing thresholds in all EHFs (i.e., 10 kHz, 12.5 kHz, 14 kHz, 16 kHz, and 18 kHz) were significantly increased for adults with tinnitus and a normal audiogram in the standard audiometric range (i.e., less than 8kHz) as compared to peers without tinnitus. For individuals with a normal audiogram, EHF loss may be a marker of those susceptible to developing tinnitus, which may aid in early identification and counseling to protect against risk factors for tinnitus.
