Hurricane Indoors

How it's made

Source

hurricane turbulence transmitted through walls: independent pink-noise sides, 45 Hz high-pass and a moving 420-1900 Hz low-pass; a shared gust drives both transmission and nonlinear level swells.

Body

broad 95/173 Hz room-pressure bands and 35-150 Hz brown noise carry the muffled structural roar. No sustained high-Q whistle: the listener is behind closed windows rather than outside a building.

Envelope

5-20 s gusts overlap faster 0.7 Hz random buffeting. Pressure blows rise in 25-65 ms and release over 0.25-0.65 s, with damped 58-105 Hz panel motion rather than subsonic DC.

Windows

gust-dependent 2-22 contacts/s excite short 460/1230/2380 Hz pane and latch bands; each contact repeats after 18-32 ms at lower strength, modelling a loose sash bouncing against its stop.

Debris

0.1-0.6 impacts/s, 3-9 ms excitation, damped wood and glass bands lasting 40-180 ms; random strength, tuning and left/right location keep hits distinct from the window chatter.

Variation

independent seeded streams vary all noise, timing, tuning and panning. Presets cover an insulated inner room, a loose sash, a boarded wall and the exposed front room during the eyewall.
