Heavy Wooden Door Slam

How it's made

Source

a heavy wooden leaf hits its jamb; 1 ms attack and 12-22 ms filtered noise model contact. A softer 35 ms pressure pulse accounts for displaced air, without a synthetic pitch dive.

Body

door bending modes at roughly 88, 143, 231, 377 and 623 Hz have 0.12-0.42 s T60. Upper modes die first; mass lowers tuning and extends the low wooden thud.

Rattle

5-8 diminishing jamb rebounds at 28-240 ms excite short wood modes and a muted latch. Loose frames have more widely separated contacts, not a continuous high-frequency hiss.

Space

low room modes at 67, 103 and 159 Hz decay in 0.55-0.95 s; dark early reflections at 21, 39 and 63 ms broaden the slam. Space is a short boom, not a long reverb wash.

Envelope

immediate slam, diminishing frame chatter, then a dark low tail; fade closes by 1.4 s.

Variation

seeded tuning +/-2%, rebound timing and strength; macros set mass, contact hardness, frame looseness and room coupling. Presets cover tight oak, loose farmhouse, sealed and corridor doors.
