Identifying hearing loss (HL) during preschool is crucial, but the most effective hearing screening method for preschoolers remains uncertain. The purpose of this study is to learn whether, compared to the gold-standard two-stage Pure-tone audiometry (PTA) + otoacoustic emissions (OAE) screening (TS-PO), single-stage OAE (SS-O) screening alone is not inferior at identifying hearing loss when performed in a community-based preschool setting. This study holds the potential to improve early hearing loss detection and intervention among D\u002FHH children, reducing the likelihood of speech and language delays.\n\nA diverse group of 13,764 preschool-age children across community-based preschool centers will be recruited. The intervention involves all subjects undergoing both PTA and OAE screening, with the order determined through randomization. Children who show potential hearing issues based on screening results or teacher concerns will receive further testing to determine the final hearing outcome. Group allocation will be post-hoc, based on their screening results.\n\nIn addition to the primary objective, the study will compare other hearing screening measures and outcomes between the two methods (TS-PO and SS-O). This approach aims to reflect the real-life effectiveness of hearing screening in a diverse population. Ultimately, the study seeks to provide insights into an optimal hearing screening method that could prevent speech and language delays among D\u002FHH children.",[68,69,70,71,72,28,73,74],"Hearing Loss","Hearing Disorders in Children","Hearing Loss, Sensorineural","Hearing Loss, Conductive","Hearing Loss, Unilateral","Hearing Loss, Mixed","Hearing Loss, Bilateral",[68,58,76,77,78,79],"Otoacoustic Emissions","Pure-Tone Testing","Childhood Hearing Screening","Childhood Hearing Loss","RECRUITING","2026-01-29",{"date":83,"type":45},"2026-02-02",{"date":85,"type":45},"2023-10-01",{"date":87,"type":21},"2028-02-01",{"name":89,"class":52},"University of California, San Francisco"]
