A new trend identified in late 2025 is the rise of "Brain Flossing," a sound therapy technique utilizing Spatialized/3D Audio to stimulate both brain hemispheres. By using head-related transfer functions (HRTF), audio engineers create an immersive experience where sound appears to move through the listener's head. This is reported to promote deeper relaxation and "neural habituation," particularly for patients with ADHD or sensory processing sensitivities.

This trend is driving a surge in the Sound Healing App market, which is expected to reach a value of over $4 billion by 2033. These apps are increasingly integrating with high-end spatial audio hardware (like the Apple Vision Pro or Sony’s 360 Reality Audio) to provide a more "visceral" therapeutic experience. Technical data on the bitrates and sampling frequencies required for high-fidelity spatial therapy can be found in the Sound Therapy Market industry outlook.
