Actor William Shatner describes his own experience with tinnitus— which began in the 1960s while filming a Star Trek episode—and shares why he’s lending his voice to Tinnitus Quest.

Tinnitus isn’t just background noise—it’s a global health crisis hiding in plain sight. More than 750 million people worldwide live with the constant ringing, buzzing, or hissing of tinnitus. For about 10 million who suffer from the severe chronic form of tinnitus, it’s not just annoying; it’s life-altering, leading to insomnia, anxiety, depression, and even suicidal thoughts.

Yet despite its staggering impact, tinnitus research remains drastically underfunded and overlooked—lagging far behind its potential.
