↵# At least 1 frequency in the audiogram (0.5–3 kHz) with thresholds at 25 dB HL or greater.
↵## A hearing loss difference greater than 15 dB HL between each ear at least in 1 frequency (0.5–3 kHz).
↵### Arithmetic mean of 0.5, 1, 2, and 3 kHz.
↵#### Arithmetic mean of 4, 6, and 8 kHz.
↵+ SDT was at least 85% or greater in all patients and controls. SNHL: sensorineural hearing loss; SRT: speech reception threshold; PTA: pure tone average; SDT: speech discrimination test.
