Washing Machine Spin

How it's made

Source

a loaded drum rotating at 800-1500 rpm; bearing friction is filtered pink noise, while motor force produces order-related tones at 6, 48 and 96 times drum rotation, with slight speed regulation.

Body

the drum and enclosed tub emphasize 65-220 Hz; damped cabinet panels color vibration at 183, 347 and 690 Hz with broad Q 2.5-5 resonances, without a ringing metallic tail.

Rhythm

smooth once-per-revolution load pulses at 13-25 Hz excite a 72 Hz suspension thud; a 1.5 Hz suspension sway groups the pulses more strongly when the laundry load is unbalanced.

Envelope

sustained high-speed operation, not startup; 0.125 Hz speed regulation and 0.25 Hz load breathing repeat across the 8 s loop. Rotation is rounded to whole cycles per 8 s; no hard impacts.

Layers

centered drum weight, subdued narrow motor whine, slightly spread bearing air and panel buzz; high-pass at 32 Hz removes unusable sub-bass, and low-pass at 5.2 kHz suppresses harsh hiss.

Variation

seeded noise and modulation phases change the bearing grain. Speed sets rotational orders; imbalance controls load pulses, cabinet controls panel vibration, and whine sets motor prominence.

Presets

balanced insulated machine, heavy uneven load, bright maximum spin, and vibrating cabinet.
