# audio (auditory)

a pattern of energy that repeats over time in a place

- Computed level: L2 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: audio  ·  Arena: audio

## Emergence
**Emerges from:** [energy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-energy.capacity), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [repeats](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-repeats.action), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent)

**Through:** the capacity for change, regular form, temporal extent, repetition, and spatial location interact to sustain a detectable signal over time and place

**Novel properties:**
- temporal coherence
- spatially bounded variation
- perceivable rhythm

## Examples
- The 440 Hz tone from a tuning fork vibrates consistently when struck, producing a standard A note. *(physics)*
- Whale songs recorded near Bermuda repeat sequences every 12 minutes across hours of underwater monitoring. *(biology)*
- The hourly chime of Big Ben in London propagates through the air as a repeating pressure wave. *(engineering)*
