Professor Larry Humes describes the “over-the-counter” (OTC) model used in the first-ever placebo-controlled double-blind randomized clinical trial of hearing aid outcomes. The study sought to compare patient outcomes when hearing aids are delivered via an audiology “best practices” model compared to an OTC model. In the context of this study, the OTC model meant that, following an exam by an audiologist, patients received a high-quality, pre-programmed hearing aid that was not fitted by the audiologist.
