Start the training in the order it is meant to be done and almost everybody hesitates in the same handful of places. These are the questions we have been asked most often over ten years of running it, answered short. Most of the answers come out the same way: nothing has gone wrong, keep going.
- Q1“4× sounds like noise. Am I doing it wrong?” — No. Everybody starts there. The goal is not to catch everything, it is to get used to sound arriving fast. If roughly half of it is landing, you are exactly where you should be — that is the half rule.
- Q2“Do I have to understand all of it?” — No. At your training speed, half is enough. Too easy and nothing is being asked of the ear; too hard and there is nothing for it to build on. Neither end grows anything.
- Q3“Why not listen slowly and carefully instead?” — Slow audio puts no load on the brain, so the speed at which you process does not move. The gain shows up on the way back down: run fast for a while and ordinary speaking speed arrives as if in slow motion.
- Q4“My ears feel blocked and tired afterwards.” — It behaves like muscle soreness. The brain is adapting to a load it has not carried before, and it usually passes in three to five days. Keep the volume low while it does — louder is not clearer.
- Q5“What about subtitles when I watch something?” — Take them off in three stages. While the ear is still closed, subtitles in a language you already know; once it starts to open, subtitles in the language you are learning; finally none at all. Subtitles are training wheels, and the whole point of training wheels is the day they come off.
- Q6“Can I do listening only, with no vocabulary work?” — For the first month, yes. Clearing the filter on the ear comes first, and once the ear opens, words begin arriving on their own. The word list will still be there when you get to it.
What all six have in common is one worry: I am catching less than I expected to. But by the half rule, the point at which about half of it slips past is precisely the point at which the ear is being built. The anxiety is a normal reading on the gauge, not a fault — it only costs you something if it stops you. (If you would like to see the whole method running on a language from the first lesson, our free Korean course is built on it — brain-hz.com/korean: 60 lessons, shadowing and speak-first modes, uncompressed audio, free and no account.)
