Users may not notice cumulative harm even as earbud use spreads across daily routines from podcasts and commuting to video meetings.

The WHO and U.S. researchers have warned of growing noise-related risks, especially among younger people.

The World Health Organization issued updated guidance saying up to 45 percent of dementia cases worldwide could be prevented or delayed.
