Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Cohort
Participants will be asked to read and sign the study ICF within the app if they agree and are willing to participate. After providing informed consent to participate, participants will be directed to select which data they want to share from the Health App via HealthKit and SensorKit to the Research app. All Research app users are asked to complete contact information and demographic questions that may be common across multiple Research app studies, such as age, race, sex, location of residence, and socioeconomic status. Participants will be asked to complete surveys approximately every other month for a total of about 1.5 hours over the entire year. Participants will be asked to complete three types of hearing tests 2-6 times per year; Interactive Tinnitus Tasks, Pure Tone Audiometry, and Speech in Noise. Participants will also be requested to complete brief on-demand surveys following high sound level measurements from headphones or the watch, at most monthly.
No interventions assigned to this group
Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Live in the United States of America at time of eligibility screening, ascertained from self-report.
* Proficient in written and spoken English, defined by self-report.
* Participants must NOT share their iCloud account, iPhone or other devices such as Apple Watch with anyone else as this would make it challenging for researchers to use their information.
* Possession of the following, ascertained from automatic hardware/software/device pairing check:
* iPhone with iOS versions capable of supporting the Research app used to complete screening eligibility.
* Optional: Apple Watch (any model) paired with iPhone; an Apple Watch Series 4 or later is required to share environmental sound levels.
