The Stealth Retrainer.

Move beyond symptom management. SijmMetry Habituation is a sophisticated protocol aimed at retraining how your brain perceives and processes sound. Based on the principles of neuroplasticity, this personalized soundscape functions as a "tuning fork" for your auditory system. Consistent use helps your brain filter out unwanted noise, paving the way for long-term recovery and mental peace.

Your long-term recovery partner, optimized for sleep and prolonged use. The ACRN tones are placed "sub-threshold"—just beneath the noise floor—and softened with a gentle hall effect. This trains your brain at a subconscious level to view the tinnitus frequency as unimportant background information. It is the art of learning to ignore the sound without conscious effort.

Optimized based on Jastreboff’s Tinnitus Retraining Therapy (TRT) and modern studies on Sub-Threshold Stimulation. A study in The Lancet highlighted that low-level, non-intrusive sound enrichment is the most effective way to achieve "habituation", the process where the brain reclassifies tinnitus as neutral background noise.
