The study also highlight that the presence of r-flag conditions (e.g., cerumen) did not impact the purchase decision of the users raising some concerns about consumers ability to self-identify their candidacy for OTC hearing aids. All the studies discuss above us either early generation DTC hearing devices (Manchaiah et al., 2017; Tran & Manchaiah, 2018) or prescription hearing aids with limit features to simulate an OTC hearing aid (Humes et al., 2017; Humes et al., 2019). Moreover, they focus on either the device or the service delivery model which limits the ecological validity and generalizability.

Overall, the key takeaway from these studies is that if users choose an appropriate device, then they are likely to have some measurable nefit from using them. 2.2 Existing and ongoing research on OTC hearing aids and service delivery models Table 1 presents a summary of complet as well as on-going RCTs studies examining OTC hearing aids and/or the Croatian Email List service delivery models. Of these, only two studies have en publish in a peer review journal (Sabin et al., 2020; De Sousa et al., 2023) and two other studies are mark as complete in the clinical trials registry. It appears that most of these RCTs (4 of the 8 list in Table 1) are industry sponsor studies examining self-fitting algorithms or process when compar to audiologist-fitt devices for regulatory approval from the FDA.

Two of the ongoing studies that are fund by a feral agency (National Institute on Deafness and Other Communication Disorders; NIDCD) and a non-profit organization (i.e., Patient-Center Outcomes Research Institute; PCORI) seem to have a large sample size (n = 240–591) and aim to investigate service delivery models. In most of the studies, OTC hearing aids that are currently on the market or likely to come to the market in the near future are ing investigat which increases their ecological TH Lists validity. All of the studies include self-report and/or havioral measures as primary and secondary outcome measures. Unlike blind RCTs (e.g., Humes et al., 2017, 2019), these studies use devices that are currently on the market with the existing branding information.
