About CalmTinnitus™
CalmTinnitus™ is a calm, at-home tinnitus sound tool developed under Leffler International Investments Pty Ltd. It is inspired by modern neuromodulation research and built to help people gently retrain how the brain reacts to tinnitus.
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.
- Safe, comfortable sound therapy
- Built-in tinnitus pitch matching
- Neuromodulation-inspired tone patterns
- Sleep-friendly audio modes
- Mobile-ready and easy to use
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.
