Investigating the Provision and Context of Use of Hearing Aid Listening Programs From Real-world Data: Observational Study

Abstract

Background Listening programs enable hearing aid (HA) users to change device settings for specific listening situations and thereby personalize their listening experience. However, investigations into real-world use of such listening programs to support clinical decisions and evaluate the success of HA treatment are lacking. Objective We aimed to investigate the provision of listening programs among a large group of in-market HA users and the context in which the programs are typically used. Methods First, we analyzed how many and which programs were provided to 32,336 in-market HA users. Second, we explored 332,271 program selections from 1312 selected users to investigate the sound environments in which specific programs were used and whether such environments reflect the listening intent conveyed by the name of the used program. Our analysis was based on real-world longitudinal data logged by smartphone-connected HAs. Results In our sample, 57.71% (18,663/32,336) of the HA users had programs for specific listening situations, which is a higher proportion than previously reported, most likely because of the inclusion criteria. On the basis of association rule mining, we identified a primary additional listening program, Speech in Noise, which is frequent among users and often provided when other additional programs are also provided. We also identified 2 secondary additional programs (Comfort and Music), which are frequent among users who get ≥3 programs and usually provided in combination with Speech in Noise. In addition, 2 programs (TV and Remote Mic) were related to the use of external accessories and not found to be associated with other programs. On average, users selected Speech in Noise, Comfort, and Music in louder, noisier, and less-modulated (all P<.01) environments compared with the environment in which they selected the default program, General. The difference from the sound environment in which they selected General was significantly larger in the minutes following program selection than in the minutes preceding it. Conclusions This study provides a deeper insight into the provision of listening programs on a large scale and demonstrates that additional listening programs are used as intended and according to the sound environment conveyed by the program name.

How Individuals Shape Their Acoustic Environment: Implications for Hearing Aid Comparison in Ecological Momentary Assessment

“…This is in agreement with Welling et al (2020 ) who found that participants rarely changed their hearing program in anticipation of a situation. In contrast, Pasta et al (2022 ) analyzed the acoustic environment before and after a program change and found that some users tended to change programs in anticipation. In the current EMA field trial, the need to get to know the hearing programs might have made it more difficult to make preemptive modifications.…”
