| Summary, etc | Background: Sloping hearing loss imposes limits on audibility for high-frequency sounds in many hearing<br/>aid users. Signal processing algorithms that shift high-frequency sounds to lower frequencies have<br/>been introduced in hearing aids to address this challenge by improving audibility of high-frequency<br/>sounds.<br/>Purpose: This study examined speech perception performance, listening effort, and subjective sound<br/>quality ratings with conventional hearing aid processing and a new frequency-lowering signal processing<br/>strategy called frequency composition (FC) in adults and children.<br/>Research Design: Participants wore the study hearing aids in two signal processing conditions (conventional<br/>processing versus FC) at an initial laboratory visit and subsequently at home during two approximately<br/>six-week long trials, with the order of conditions counterbalanced across individuals in a<br/>double-blind paradigm.<br/>Study Sample: Children (N 5 12, 7 females, mean age in years 5 12.0, SD 5 3.0) and adults (N 5 12,<br/>6 females, mean age in years 5 56.2, SD 5 17.6) with bilateral sensorineural hearing loss who were<br/>full-time hearing aid users.<br/>Data Collection and Analyses: Individual performance with each type of processing was assessed<br/>using speech perception tasks, a measure of listening effort, and subjective sound quality surveys at<br/>an initial visit. At the conclusion of each subsequent at-home trial, participants were retested in the laboratory.<br/>Linear mixed effects analyses were completed for each outcome measure with signal processing<br/>condition, age group, visit (prehome versus posthome trial), and measures of aided audibility as predictors.<br/>Results: Overall, there were few significant differences in speech perception, listening effort, or subjective<br/>sound quality between FC and conventional processing, effects of listener age, or longitudinal<br/>changes in performance. Listeners preferred FC to conventional processing on one of six subjective sound<br/>quality metrics. Better speech perception performance was consistently related to higher aided audibility.<br/>Conclusions: These results indicate that when high-frequency speech sounds are made audible with<br/>conventional processing, speech recognition ability and listening effort are similar between conventional<br/>processing and FC. Despite the lack of benefit to speech perception, some listeners still preferred FC,<br/>suggesting that qualitative measures should be considered when evaluating candidacy for this signal<br/>processing strategy. |
