Objectives To assess knowledge retention after video‐based hearing health education and measure headphone listening behavior change using a novel smartphone application. Methods In this prospective longitudinal study, students participated in video‐based hearing health education and hearing screening sessions. Hearing health knowledge was assessed in students and parents after 6 weeks. A novel smartphone application was created to measure daily noise exposure based on volume settings with headphone use and to display the National Institute for Occupational Safety and Health (NIOSH) noise doses with alerts for cumulative daily doses nearing the maximum. Results Seventy‐six teenage students and parents participated. Eighty three percent of participants identified as a racial or ethnic minority and 66% were of low‐income socioeconomic status. Hearing health knowledge was retained in students 6 weeks after education and parents’ knowledge improved from baseline. The smartphone app was installed on 12 student phones, and 25% of days monitored exhibited noise doses that exceeded the NIOSH maximum. App use for at least 10 days by nine students showed a significant reduction in average daily noise dose and time spent at the highest volume settings during the second‐half of app use. Conclusions Video‐based hearing health education with knowledge question reinforcement was associated with knowledge retention in students and improved parental attitudes and knowledge about hearing conservation. A smartphone app with a real‐time display of headphone cumulative noise exposure dose identified at‐risk students. The integration of hearing health education, hearing screening, and digital health tools has promised to promote positive behavior changes for long‐term hearing conservation. Level of Evidence 4 Laryngoscope, 133:2007–2013, 2023 Turn down the volume: A longitudinal study showed video‐based hearing health education improved teen and parent knowledge on NIHL prevention. A smartphone app with noise dose alerts also encouraged teens to reduce noise exposure and volume settings with headphone use.
