| 520 3# - SUMMARY, ETC. | |
| Summary, etc | Objectives: Modern hearing aid (HA) devices include a collection of<br/>acoustic signal-processing features designed to improve listening outcomes<br/>in a variety of daily auditory environments. Manufacturers market<br/>these features at successive levels of technological sophistication. The<br/>features included in costlier premium hearing devices are designed to<br/>result in further improvements to daily listening outcomes compared<br/>with the features included in basic hearing devices. However, independent<br/>research has not substantiated such improvements. This research<br/>was designed to explore differences in speech-understanding and listening-<br/>effort outcomes for older adults using premium-feature and basicfeature<br/>HAs in their daily lives.<br/>Design: For this participant-blinded, repeated, crossover trial 45 older<br/>adults (mean age 70.3 years) with mild-to-moderate sensorineural hearing<br/>loss wore each of four pairs of bilaterally fitted HAs for 1 month. HAs<br/>were premium- and basic-feature devices from two major brands. After<br/>each 1-month trial, participants’ speech-understanding and listeningeffort<br/>outcomes were evaluated in the laboratory and in daily life.<br/>Results: Three types of speech-understanding and listening-effort data<br/>were collected: measures of laboratory performance, responses to standardized<br/>self-report questionnaires, and participant diary entries about<br/>daily communication. The only statistically significant superiority for the<br/>premium-feature HAs occurred for listening effort in the loud laboratory<br/>condition and was demonstrated for only one of the tested brands.<br/>Conclusions: The predominant complaint of older adults with mildto-<br/>moderate hearing impairment is difficulty understanding speech in<br/>various settings. The combined results of all the outcome measures<br/>used in this research suggest that, when fitted using scientifically based<br/>practices, both premium- and basic-feature HAs are capable of providing<br/>considerable, but essentially equivalent, improvements to speech<br/>understanding and listening effort in daily life for this population. For HA<br/>providers to make evidence-based recommendations to their clientele<br/>with hearing impairment it is essential that further independent research<br/>investigates the relative benefit/deficit of different levels of hearing technology<br/>across brands and manufacturers in these and other real-world<br/>listening domains. |
