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.
Foundations · builds on
LoudspeakercausesSound waveEstablished
loudspeaker produces a sound wave.
Mechanism: It moves air to radiate a sound wave.

Enables · leads to
Auditory perceptiondepends onSound waveEstablished
Auditory perception depends on incoming sound waves.
Mechanism: Without a sound wave reaching the ear there is nothing to perceive.
Ultrasound imagingdepends onSound waveEstablished
Ultrasound imaging depends on sound-wave.
Mechanism: Ultrasound imaging sends high-frequency sound waves into tissue and records their echoes.
System context
Sound waveis aWaveEstablished
A sound wave is a kind of wave.
Mechanism: Sound is a pressure wave: vibrating air passes the disturbance from molecule to molecule, exactly the wave pattern seen across physics.
- University Physics (OpenStax) verifiedmoderate evidence
Amplitudeis part ofSound waveEstablished
Amplitude is a property of a sound wave.
Mechanism: Amplitude measures how far the wave pushes air from rest.
Frequencyis part ofSound waveEstablished
Frequency is a property of a sound wave.
Mechanism: Frequency counts how many wave cycles pass each second.
Infrasoundis aSound waveEstablished
infrasound is a kind of a sound wave.
Mechanism: Infrasound is a sound wave too low in frequency to hear.

Sound intensityis part ofSound waveEstablished
sound intensity is part of a sound wave.
Mechanism: Intensity is the energy-flow property of a sound wave.

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 Auditory perception and Loudspeaker from 2 to 7 steps (they stay connected — alternative routes exist).
structural · Structural removal simulation — not a historical or causal counterfactual.
50% of its relationships cross field boundaries, reaching 13 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 · 18 of 18 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Strengths
- Cross-disciplinary connector — 50% of its relationships cross field boundaries. structural
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
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
What builds on this
2 concepts build on this directly, 4 in total, across 8 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Wave, Frequency, Amplitude and Sound pressure.

Sound is a wave: something vibrates, pushing air back and forth. Those pressure changes travel to your ear. Faster vibrations and bigger pushes change what you hear.
