剧院座席
Overview
Theater design creates intimacy between performer and audience. This skill covers sight-line geometry, acoustic engineering for music and speech, stage-house design, and the eternal tension between capacity and closeness.
When to Use
- Designing theaters, concert halls, or black-box spaces
- Analyzing sight lines from every seat
- Engineering acoustics for music, speech, or both
- Designing stage houses, fly towers, and rigging systems
Key Principles
- Sight lines — C-value ≥ 90mm for unobstructed view of full stage.
- Acoustics — RT60: 1.0-1.5s for speech; 1.8-2.2s for symphonic music.
- Intimacy — maximum distance to stage < 20m for drama; < 30m for music.
- Stage house — proscenium, thrust, or in-the-round; each demands different seating geometry.
- Fly tower — height ≥ 2.5x proscenium height for scenery flying.
Process
- Define performance type and capacity target.
- Select stage configuration (proscenium, thrust, black box).
- Design seating geometry with sight-line analysis.
- Model acoustics for target RT60 and early reflections.
- Design stage house and fly tower.
- Plan front-of-house (lobbies, bars, restrooms) for intermission flow.
Common Pitfalls
- Too many seats — 1500-seat drama theater feels empty at 800.
- Bad acoustics for speech — long RT60 muddies dialogue.
- Ignoring orchestra pit — musicals and opera need flexible pit space.
- Fly tower too low — scenery can't be stored or flown.
Verification Checklist
- [ ] C-value ≥ 90mm from every seat
- [ ] RT60 matches performance type
- [ ] Max distance < 20m (drama) / < 30m (music)
- [ ] Stage house and fly tower sized
- [ ] Intermission flow for front-of-house
