HEARING LOSS, AIDS
Personal sound amplification products (PSAPs) and over-the-counter (OTC) hearing aids are becoming a new alternative for individuals with hearing loss. Although a growing body o advantages of using these devices at the group level, there has been limited focus on individual differences. Therefore, the full extent of their benefits remains unknown. To clarify the interindividual variability in benefits, the present study used a cross-over design to assess the beneficial effects of PSAPs on speech perception in noise and self-reported listening effort in two counterbalanced sessions. Consistent with previous research, this study supports that PSAPs use is associated with speech-in-noise benefits in terms of performance and listening effort. However, the benefits are small and only observed for some individuals.
