A432 — one frequency, four wayscolour · audio · video · vibration · frequency is the shared thread; the rest is honestly flagged

frequencyA432 — the anchor (= 16 × 27)

colour

Double 432 Hz 40 octaves (×2⁴⁰) and it lands in visible light: ≈ 475 THz, wavelength ≈ 631 nm — a red (via c = λf).

A chosen octave-mapping, not the sound's "true colour" — light is an EM wave, sound a pressure wave.

♪

audio

A pressure wave at 432 Hz — a pitch you hear (20 Hz–20 kHz). Tuning A to 432 multiplies every note by 432/440 (−31.8 cents).

video

The same frequency as motion: 432 Hz itself is far too fast to see, so this spins at the divided rate 2 Hz. Displays refresh in Hz; motion fuses to smooth above ~60–90 Hz.

A rate of a process — a real frequency, but not a wave in a medium.

vibration

Felt, not heard: tactile receptors span ~0.4–1000 Hz, the Pacinian peak near ~250 Hz (where device actuators are tuned). The one literal cross-domain kinship — vibration and sound are both mechanical waves.

The shared math is real (frequency, the octave = ×2, c = λf) and sound↔vibration is a literal mechanical kinship; but a sound and a colour are different physics (a pressure wave vs an EM field) that merely share the abstract property of frequency — the “colour of A432” is a chosen octave-mapping, not the sound’s true colour. The thin relaxation studies are real but small and not 432-specific; everything beyond “a pleasant, slightly lower pitch” is flagged.

A440 is the standard (ISO 16; London 1939 → ISO R 16 1955 → ISO 16 1975); before standardization pitch genuinely varied ~400–460 Hz (the French diapason normal was 435 Hz in 1859).
432 = 2⁴ × 3³ = 16 × 27 — twenty divisors, integer octaves (27·54·108·216·432·864). It is MORE composite than 440 (= 2³ × 5 × 11, sixteen divisors, with an awkward factor of 11).
Tuning A to 432 multiplies every note by 432/440 ≈ 0.98182 — a uniform shift down of about 31.8 cents; the scale’s shape is identical, only the anchor moves.
Reference pitch and temperament are independent choices; just / Pythagorean intervals really are acoustically purer than equal temperament — but that purity is the temperament, not the number 432.
Frequency is the one quantity shared by sound (20 Hz–20 kHz, a pressure wave), light (~400–790 THz, an EM wave, c = λf), haptic vibration (~0.4–1000 Hz, the Pacinian receptors peak ~250 Hz) and motion (frame/refresh rate in Hz).
The octave bridge: 432 Hz doubled 40 times is ≈ 475 THz ≈ 631 nm — a red light. Sound↔vibration is a literal kinship (both mechanical waves); sound↔colour is a chosen octave-mapping, not a physical identity.
A few small RCTs (n ≈ 40–54) found music at 432 Hz relaxes the body marginally more than 440 on some autonomic measures (cortisol, heart rate) — but the authors themselves say they cannot attribute it to 432 specifically rather than to a lower, gentler pitch.
