Note: Data are represented as mean ± SD. HA, hearing aid; dBA, A-weighted decibels; SNR, signal-to-noise ratio; SD, standard deviation.
a
The prices of the hearing aids were based on the Taiwanese market price; the costs of the AirPods were the official prices from the company website (https://www.apple.com/airpods/).
b
Noise and the targeting speech were both from the front direction of each participant.
c
Noise and the targeting speech were from different direction (noises were from the left side of each participant).
