Tinnitus (ringing in the ears) is thought to happen because certain brain cells in the hearing system start firing too much AND too much together, especially at the pitch that matches the tinnitus sound. When brain cells become overly synchronized, the sound becomes louder and harder to ignore.
Spectral ripple sound therapy (aka cross-frequency de-correlating stimulus modulation) is a new type of sound designed by researchers in 2025 to break up this over-synchronization. The goal was to make the brain’s activity at tinnitus-related pitches less tightly linked, which could make the tinnitus seem quieter.
The spectral ripple sound therapy covers a wide range of pitches, especially around the person’s tinnitus pitch.
Unlike regular neuromodulated sounds, where different pitches change in predictable ways, this sound keeps changing how the pitches relate to each other. Because nothing stays in sync for very long, the brain can’t lock onto stable patterns. Over time, this may reduce how strongly the tinnitus signal influences perception.
Traditional sound therapies (neuromodulation) often use predictable patterns or remove certain frequencies. This new method keeps sound energy across all relevant pitches, but removes consistent patterns or relationships between pitches. This prevents the brain from reinforcing the tinnitus signal.
Based on 2025 research, spectral ripple therapy had a significant effect in reducing tinnitus loudness over 6 weeks of regular listening, and this reduction persisted for at least a further 3 weeks of no listening.
