Electric Kettle Coming to Boil

How it's made

Source

an electric heating plate nucleates tiny steam cavities that collapse in cooler water. Filtered pink and white noise models this 180-4200 Hz granular roar, rising before bulk boiling.

Body

water-loaded kettle walls colour the excitation at 150-310 and 420-870 Hz (Q 1.1-2.2). A separate 45-390 Hz turbulent bed supplies weight without a pitched electrical oscillator.

Events

5-95 bubbles/s, radii 2.6-10 mm, produce short rising 326-1250 Hz chirps; 1 ms soft attacks and 20-85 ms envelopes soften attacks; a 2.4-3.6 kHz low-pass rounds the liquid transients.

Envelope

heat rises over 6-10 s; the cavitation roar peaks at 70 percent heat, then softens as water reaches boiling. Bubble density and 1.3-5.5 kHz steam grow into the final rolling boil.

Modulation

independent 0.7 and 3.1 Hz random drifts cluster bubbles and move the broad roar band. The 12 s texture holds a breathing boil after the rise, and scales its rise for shorter renders.

Variation

seeded event radii, rise, level and narrow pan vary; four presets change water load, wall damping, heat-up time and steam exposure. Dry close perspective, no whistle or room reverb.
