Apple Hearing Study

This week's top stories include a plea to increase efforts to collect ethnicity data when administering vaccinations, and Apple and the University of Michigan sharing the first results from the Apple Hearing Study.

One in four participants has a noise exposure over WHO's daily limit and many have undiagnosed hearing loss.

iOS users can now sign up for studies on women's health, movement and heart health, and the effects of noise exposure on hearing.

Amidst the unveiling of its newest consumer smartphones, tablets and smartwatches, the tech company said it will begin enrolling consumers into its hearing, cardiovascular and women's health studies later this year through an upcoming app.
