Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Enables · leads to
Loudnessdepends onAmplitudeEstablished
Loudness depends on amplitude.
Mechanism: Bigger amplitude carries more energy and is heard as louder.
Sound intensityemerges fromAmplitudeEstablished
sound intensity emerges from amplitude.
Mechanism: Intensity grows with the square of the wave's pressure amplitude.

System context
Amplitudeis part ofSound waveEstablished
Amplitude is a property of a sound wave.
Mechanism: Amplitude measures how far the wave pushes air from rest.
Amplitudeis part ofWaveEstablished
Amplitude is the size of a wave's swing.
Mechanism: Amplitude is a property of a wave: the size of its swing from the resting line, which sets how loud a sound or bright a light is.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Removing this node lengthens the structural route between Envelope (audio) and Gain (audio) from 2 to 5 steps (they stay connected — alternative routes exist).
structural · Structural removal simulation — not a historical or causal counterfactual.
33% of its relationships cross field boundaries, reaching 8 other disciplines — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Currently dark in the atlas: no verified source · no key date stored · 6 of 6 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 6 → 38 → 122 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
