Table 1: Age is given in years (y). Gender is described as f (female) or
m (male). Puretone average (4-PTA) is calculated as average decibel (dB)
hearing level (HL) at the frequencies 500 Hertz (Hz), 1000 Hz, 2000 Hz
and 4000 Hz. Word recognition scores (WRS) are calculated using Freiburg
monosyllables at (@) 80 dB HL. Hearing of the contralateral side
resulted in the diagnoses of single sided deaf (SSD), asymmetric hearing
loss (AHL) or bilateral complete hearing loss larger than 100 dB HL (≥
100 dB). Contralateral 4-PTA = 4-PTAC
