Interindividual variability in the benefits of personal sound amplification products on speech perception in noise: A randomized cross-over clinical trial.

ABSTRACT:

Objective

The aging population is prone to hearing loss, which has several adverse effects on quality of life, including difficulty following conversations in noisy environments. Personal Sound Amplification Products (PSAPs) are a less expensive, over-the-counter alternative to traditional, more expensive hearing aids. Although some studies have shown that PSAPs can mitigate hearing loss, the literature generally only addresses group differences without considering interindividual variability. This study aimed to 1) determine how PSAPs affect listening effort and speech perception in noise and 2) measure interindividual variability and identify contributing demographic and health factors.

Design

We used a cross-over design in which all participants were assigned to each cond
