Rain on a Car Roof

How it's made

Source

liquid drops excite a parked car's roof and laminated windshield; rounded 0.5-1.5 ms noise attacks and 5-24 ms splashes avoid the hard rebounding clatter of hail.

Body

damped sheet-metal modes at 175, 312, 583 and 1060 Hz decay in 35-135 ms; headlining absorbs upper modes. Laminated glass adds weak 1.8-4.3 kHz modes lasting 12-28 ms, without bell-like ringing.

Layers

decorrelated pink rain wash at 220 Hz-4.6 kHz, roof impacts spread across the cabin, and narrower frontal glass taps. A broad 190 Hz cabin response adds enclosure without a long reverb.

Envelope

steady Poisson roof drops at 16-110/s and glass taps at 9-69/s over a 12 s seamless loop; a slow random +/-8 percent intensity drift changes density and wash, with no storm crescendo.

Variation

each drop varies strength, pan, contact length and modal coupling; roof modes vary +/-4 percent by impact position. Rainfall controls density; roof/glass balance and lining control tone.

Presets

fine drizzle exposes separate drops; roof drumming emphasizes the panel; windshield patter favors frontal glass; a soaking shower increases density and the diffuse wash inside the sealed cabin.
