About CalmTinnitus™

Created from real experience

CalmTinnitus™ was created by someone living with high-pitch tinnitus for over 50 years — including severe, war-related acoustic trauma. This is not theory. This is lived experience transformed into a practical tool.

Our mission

To give tinnitus sufferers a simple, affordable, research-informed tool that can be used every day — without expensive hardware, clinics, or complicated protocols.

Not a miracle cure

No sound therapy can promise a cure — and we will never claim one. But many people find that regular, structured training helps reduce the intensity, stress, and intrusiveness of tinnitus.

Responsible and honest

CalmTinnitus™ is a self-help training tool. It does not replace ENT care, audiology evaluation, or professional medical treatment.
