Ears were categorized by degree of hearing loss (PTA in dB HL). The classification of QuickSIN SNR loss is also provided for each degree of hearing loss (Etymotic Research 2006).

PTA indicates pure-tone average; SNR, signal-to-noise ratio; VS, vestibular schwannoma; WRQ, word-recognition in quiet.
