Pure-Tone Audiometry Hearing Thresholds
Hearing thresholds were assessed by pure-tone audiometry at 250, 500, 1000, 2000, and 4000 Hz in both ears and compared between the study and control groups.
Time frame: Baseline
Acoustic Reflex Thresholds
Ipsilateral and contralateral acoustic reflex thresholds were assessed at 500, 1000, 2000, and 4000 Hz and compared between the study and control groups.
Time frame: Baseline
Plan to share: No — Individual participant data will not be shared with other researchers. Only aggregate study results will be reported in the publication.
