How it's made
- Source
- a belt motor parts two steel elevator panels; drive at 95–210 Hz carries quieter 2nd, 3rd and 6th gear partials, with 0.6 percent speed wander and speed-linked amplitude ripple.
- Body
- independent roller noise excites broad steel bands near 135, 310 and 690 Hz; guide friction occupies 450–2400 Hz. Panels separate gently in stereo around the central motor.
- Envelope
- 0.3 s acceleration, steady travel, then 0.55 s controlled deceleration; friction follows speed. Two padded stops 24 ms apart mark full opening near 2.1 s by default.
- Stop
- 9 ms low-passed noise contacts excite panel modes at 92, 173, 327 and 611 Hz with 0.08–0.24 s T60; a 65–85 Hz rubber thump decays in 0.15 s. No latch slam or pneumatic vent.
- Variation
- named RNG streams detune drive and panel bands by 1–3 percent and vary stop strength. Travel, mass, drive prominence and guide wear distinguish passenger, quiet, freight and worn doors.
- Space
- dry close perspective; low-cut at 38 Hz, softened upper spectrum and zero-ended fades.
