*
P-values based on Kruskal-Wallis tests for continuous variables and Fisher’s exact for categorical variables.
SSI-ICM – Synthetic Sentence Identification with Ipsilateral Competing Message
DSI – Dichotic Sentence Identification, free report mode
DDT – Dichotic Digits Test
PTA – average of behavioral thresholds at 1 2 3kHz in dBHL
DPOEa – Distortion Product Otoacoustic Emission average at 1 2 3 kHz; were done only in the ear with better (i.e. lower) pure-tone thresholds..
ABR – latency in msec of wave V of the Auditory Brainstem Response
MLR - latency of poorer wave Pa
LLR - latency of poorer wave P2
