🧠 Speed Bible App Principles

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
