Background Transportation road maintenance and repair workers, or “maintainers,” are exposed to hazardous and variable noise levels and often rely on hearing protection devices (HPD) to reduce noise‐exposure levels. We aimed to improve upon HPD use as part of the HearWell program that used a Total Worker Health, participatory approach to hearing conservation. Methods Full‐shift, personal noise sampling was performed during the routine task of brush cutting. Work activities and equipment were recorded and combined with 1‐min noise measures to summarize personal noise‐exposure levels by equipment. Using noise‐monitoring results, HPD noise reduction ratings, and input from worker‐based design teams, a noise‐hazard scheme was developed and applied to the task and equipment used during brush cutting. Results Average (standard deviation) and maximum Leq 1‐minute, personal noise‐exposure levels recorded during brush cutting included chainsaws at 92.1 (7.6) and max of 111 dBA, leaf blowers at 91.2 (7.5) and max 107 dBA, and wood chipper at 90.3 (7.3) and max of 104 dBA. The worker‐designed noise‐hazard scheme breaks down noise exposures into one of three color bands and exposure ranges: red (over 105 dBA), orange (90‐105 dBA), or yellow (85‐90 dBA). The scheme simplifies the identification of noise levels, assessment of noise‐hazard, and choice of appropriate hearing protection for workers. Conclusion Combining noise‐exposure assessment with intervention development using participatory methods, we characterized noise exposure and developed an intervention to educate and assist in protecting workers as they perform noisy tasks.
Purpose The purpose of this study was to better understand the behaviors that hearing aid users engage in to manage batteries. Method Two arms of research, a survey of audiologists ( n = 110) and qualitative interviews with adult hearing aid users ( n = 13), were conducted. Surveys were distributed and collected both via paper and online methods. Descriptive analyses of survey results were conducted to report on common threads. Qualitative interviews were conducted with video recording for transcription purposes. These transcripts were then coded thematically to identify shared themes across participants. Results Results of this study highlight the variability in behavior between provider-recommended strategies (preemptive battery management) and the reactive/delay strategies that are implemented by users. Patient reports indicate several challenges related to changing their batteries including limited information on hearing aid batteries, physical/sensory challenges to the act, and the social impact of having to change hearing aid batteries. Concurrently, patients express a wide range of strategies to address other challenges including engaging in cost-conscious behaviors when managing batteries (both purchasing and deciding to replace) and maintaining a collection of easily accessible batteries for use. Conclusions Hearing aid batteries are a topic that reflect social and economic factors in a patient's life. While providers may report they cover these topics sufficiently, challenges related to batteries may need specific elucidation by the clinician to ensure adherence to recommendations and functioning devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
