Note: HA, hearing aid; CI, confidence interval; dBA, A-weighted decibels; SNR, signal-to-noise ratio.

^aNoise and the targeting speech were both from the front direction of each participant.

^bNoise and the targeting speech were from different direction (noises were from the left side of each participant).
