A concert hall has 24 billion acoustic degrees of freedom
Evidence
At the highest audible frequencies the wavelength is about 1 cm. Each such cube has three degrees of freedom to vibrate. Thus, a hall with dimensions 20 × 40 × 10 metres has about 3 · 2000 · 4000 · 1000 = 24, 000, 000, 000 degrees of freedom to vibrate! — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 298

- CANDY: The 24-billion-degrees-of-freedom figure is a vivid stand-alone fact for explaining why room acoustics resist exact computation.
