Red Light Therapy & Hearing Loss: Evidence vs. Hype

Red light therapy is being promoted online as a treatment for hearing loss and tinnitus, but what does the evidence actually show?

In this episode, Dr. Layne Garrett of Timpanogos Hearing & Tinnitus explains why red light therapy sounds biologically plausible, how photobiomodulation may affect mitochondrial energy production, and why animal studies do not automatically translate into real hearing improvement for humans. He also discusses the current limits of controlled human research, the difference between short-term tinnitus relief and measured hearing improvement, and why testimonials should not be confused with clinical outcomes.

For patients with hearing loss, tinnitus, or speech clarity concerns, this episode offers a careful, evidence-based way to evaluate treatment claims before spending significant money. Dr. Garrett also explains why properly fitted hearing aids verified with REM remain one of the strongest evidence-supported options for documented hearing loss.

Dr. Garrett has more than two decades of experience helping patients with tinnitus, complex hearing loss, and advanced hearing technology through a medical-model approach focused on accurate diagnosis, outcome tracking, and whole-person
