Canonical Power learning unit · TLU-PWR-076

On coded eight-second mixtures A and B, the learner inventories the three generated sources, marks each supplied onset or offset to the nearest one-second grid line, names the pitch, timing or timbre cue used, and tests one written unmasking prediction against the companion file.

Explanation is not permission.

This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.

Complete bounded explanation

What this power means.

Capability to develop or express auditory scene analysis in a declared context without inheriting broader claims.

What the current evidence supports

People can learn to separate selected auditory patterns, but the learning may be tightly tuned and does not establish general ‘cocktail-party’ mastery.

How to observe or measure it without overclaiming

Predeclare number/type of sources, cue dimensions, target, masker, accuracy and new-scene transfer; neural responses remain mechanism measures.

Myth

Choose one voice in any crowd

Metric

Target-source accuracy in novel multi-source scenes with fatigue

Boundary

A trained vowel or modulation threshold does not create universal selective hearing.

Negative and limiting findings

  • Learning on one spectrotemporal modulation did not generalise broadly and some untrained detection worsened.
  • No mapped study established daily multi-speaker transfer.

Claims this evidence cannot support

  • Isolate any sound at will
  • Switch off background noise with the brain
  • Train universal auditory scene analysis
  • Neural change proves real-world benefit

How to learn this Power now.

On coded eight-second mixtures A and B, the learner inventories the three generated sources, marks each supplied onset or offset to the nearest one-second grid line, names the pitch, timing or timbre cue used, and tests one written unmasking prediction against the companion file.

  1. Get readyUse synthetic or consented learner-owned audio only.
  2. Learn the method8 concrete steps teach the permitted method from start to finish.
  3. See right and wrong6 comparisons show correct or safer execution beside common wrong or riskier choices.
  4. PractiseAfter 48 hours, analyse Scene B with the identical inventory/replay limits and predict what B-probe will do to the 3-second burst. On later weeks, a helper may move one burst time or one steady-track onset while preserving three tracks and eight seconds; change only that overlap feature, never playback level.
  5. Check progressRecord correct, missed and false sources, onset/offset error, named cue, replay, burden and exact scene/audio configuration. Record whether the one-stem continuity probe confirmed the predicted masking or grouping relation.

Authority boundary: Titan teaches a concrete low-stakes method step by step while keeping evidence and transfer claims bounded. The method is Power-specific; its actionability follows this treatment.

A Power-specific tutorial is available at /tutorials/pwr-076/. It contains a plain-English method, 8 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence. Its self guided mode remains controlling.
