title: Room-Acoustics Reverberation
purpose: Test whether flatulence is acoustically integrated into a reverberant tiled environment without becoming an exaggerated cinematic effect.
scene:
  location: clean empty tiled locker-room wash area
  subjects:
  - one fully clothed adult washing hands at a sink
  lighting: bright neutral overhead lighting
  acoustic_character: small hard-surfaced tiled room with mild natural reverberation
target_actor:
  description: adult woman in casual clothes standing at the sink
  role: sole event source
timeline:
- window_seconds:
  - 0.0
  - 2.5
  required: target washes hands; water and room ambience are audible; no fart occurs
- window_seconds:
  - 2.5
  - 4.0
  required: target produces exactly one short natural fart while remaining at the sink; sound has mild plausible room reverberation
- window_seconds:
  - 4.0
  - 8.0
  required: reverberation decays naturally; target gives a subtle private reaction and continues washing hands
audio:
  fart_audible: true
  fart_count: 1
  fart_character: short natural human flatulence with restrained tiled-room reverberation
  ambient: running sink water, ventilation hum, mild room reflections
  dialogue: none
camera:
  framing: medium-wide
  movement: static
  target_visible: true
  cuts: 0
prohibited:
- visible gas or smoke
- defecation
- explosion-like echo
- additional fart events
- dialogue
- music
- toilet-use depiction
