Car Door Close

How it's made

Source

a padded car door compresses its rubber seal; 3 ms rise, 28 ms low-passed contact noise. A preceding 35 ms air displacement narrows from 1.8 kHz to 450 Hz as the opening closes.

Body

damped sheet and trim modes at 83, 137, 219, 346, 571 and 913 Hz have 90-360 ms T60. A broad 100-155 Hz cabin pressure resonance adds a dull pop without a synthetic pitch drop.

Latch

the rotary catch seats 14-26 ms after contact, then a quieter pawl follows 12 ms later; 1.2-3.3 kHz filtered noise and short inharmonic modes form a click, never a ringing clang.

Envelope

air moves immediately; contact peaks near 40 ms. High modes disappear before the low panel settles. A 620-700 ms finishing fade leaves 100 ms of silence within the 0.8 s maximum.

Variation

seeded tuning varies by 1.5 percent and latch timing by 2 ms. Mass lowers the modes; seal softens contact, pressure controls the pop and damping shortens the panel vibration.

Presets

padded sedan, light compact, heavy utility door and close cabin perspective vary mass, seal absorption, latch prominence and pressure balance. Dry mono foley, without room reverb.
