Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The Quick Speech-in-Noise (QuickSIN) Test will be used as the primary effectiveness endpoint. QuickSIN is a quick and easy test that can measure an individual's ability to understand speech in noise. The secondary effectiveness endpoint will be assessed by using the Abbreviated Profile of Hearing Aid Benefit (APHAB). The APHAB was designed to evaluate the effect of hearing impairment or benefit in daily life APHAB and has long been considered the gold standard for patient-reported perceived benefit.
For this clinical study to be deemed successful, the self-fitting method needs to yield outcomes (namely QuickSIN and APHAB scores) which are non-inferior to the clinician-fitting method. Non-inferiority refers to an outcome where the new intervention (in our case, self-fitting) is not significantly worse than the established intervention (in our case, clinician-fitting), while also accounting for a clinically-significant margin.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Screening, intake and first fit (either clinician-fitting or self-fitting )
This clinical trial compares two methods of fitting individuals who suffer from hearing loss with a hearing aid device. Subjects will wear the hearing aid after receiving the clinician-fitting (device fitted by a clinician according to standard clinical best practice procedures) and self-fitting (device fitted by the user directly without assistance from a clinician following an automated assessment and fitting process) for two weeks each, totaling to approximately 1 month of wear throughout the trial. During the first visit, all individuals will go through intake procedures and a basic audiologic evaluation. After this is completed, individuals will be randomly assigned into one of two arms of the study. Individuals in the first visit of the study, will receive either the clinician-fitting or the self-fitting method for the first two weeks, then will switch to the experimental self-fitting or the clinician-fitting method for the last half. The order of the fitting will be randomized.
Hearing aid
The hearing aid is a receiver-in-canal style hearing aid which can be programmed and adjusted by proprietary software and through a dedicated smartphone application
Second fit (either clinician-fitting or self-fitting )
In the second visit of the study, individuals who randomly received the conventional clinician-fitting for the first two weeks (first period) will switch to the experimental self-fitting for the remainder of the study (second period). Conversely, individuals who received the experimental self-fitting method for the first two weeks (first period) will switch to the clinician-fitting method for the last two weeks (second period). The same within-subject crossover design will be followed in both clinical sites and for all individuals who were enrolled in the study.
