🧠 Speed Bible App Principles
🎯 Key Summary
What it is
• Speed Listening = brain training that raises processing speed by re-listening to the same content faster and faster (1-4x, 3 stages)
Why it works (evidence)
• US NIH ACTIVE trial — older adults with speed-of-processing training had 25% lower dementia risk 20 years later
• High-frequency (Tomatis) & gamma (40Hz) stimulation, built into the actual audio by the BrainHz engine
How to train
• Sound (auditory) + subtitles (visual) together — reading along at 3-4x trains both at once
• WAV (48kHz) recommended — preserves highs up to 24kHz (MP3 cuts off at 12kHz)
• Use wired earphones or wired bone conduction — Bluetooth re-compresses and cuts highs (see Sound & Text tab)
• Korean Bible text, rich in phonemes and highs, is optimal training material
What improves
• Better focus, memory, and comprehension + learning & foreign-language listening gains
• Maintains/improves high-frequency hearing (hearing age) that declines with age
