👂 Speed Training

🧠 How It Works

🎯Why Speed Listening? 3-min

· Brain training: re-listen to the same text faster (1-4x)

· US NIH study — 25% lower dementia risk

· Sound + subtitles = visual & auditory at once

🎬Just listening made ears younger

· 2 hearing-rejuvenation videos (senior · junior)

· The video itself is speed listening (2-4x)

· Real case: hearing age 70s→20s in a month

🧠25% lower dementia risk — proven

· US NIH ACTIVE trial (~2,000 people, 20 yrs)

· Highs (Tomatis) + 40Hz gamma stimulation

· Fast audio mobilizes the brain's spare capacity

📊Sharpen focus, memory & hearing

· Brain — focus, memory, comprehension, reaction

· Health — hearing age, dementia prevention, stress

· Learning — reading speed, listening, work

🔊MP3 drops highs. WAV keeps them.

· WAV 48kHz keeps highs to 24kHz (MP3 cuts 12k)

· Wired+DAC or bone conduction (BT re-compresses)

· Korean Bible: phoneme- & highs-rich material
