NPR: An unprecedented study that could pave the way for safer listening practices

In 2019, Neitzel and his team at the University of Michigan launched the Apple Hearing Study, a first-of-its-kind study with Apple geared toward understanding people’s daily sound exposure and listening habits. Over 180,000 people have volunteered to share their phone data and Apple watch data with Neitzel and his team, who are examining how long and loud people are listening, and the noise levels in their environment.
