How it's made
- Source
- a boot kicks a thin sheet-steel can. The strike is a 2–6 ms low-passed noise thump (foot and dented wall) plus a short metallic crack; a hard kick is brighter and shorter.
- Body
- a hollow cylinder. A dominant shell/air mode near 190 Hz gives the "bang"; inharmonic sheet modes (ratios ≈ 1 : 1.62 : 2.31 : 3.4 : 4.9, 0.25–0.9 s) give the metal ring; a 120–260 Hz cavity resonance adds the hollow boom.
- Wobble
- a flexing thin wall modulates the ring. A 6–11 Hz amplitude wobble on the upper modes decays with the ring, as the can rocks and settles.
- Rattle
- the lid and loose debris bounce and roll. Poisson ticks (1.5–5 kHz, 3–12 ms) start dense and thin out as the can rolls to rest, under a band-passed rolling-noise bed that follows the same fade.
- Envelope
- crack in 1 ms, body falls over ~0.7 s, rattle lasts to ~1.1 s; everything is gone by 1.3 s.
- Variation
- `rng` detunes the modes by ±1.5 %, jitters tick timing, pitch and strength.
