566 Hz Wavelength

How Long Is a 566 Hz Wavelength?

A 566 Hz sound wave has a wavelength of 0.61 meters, 60.64 cm, 1.99 feet (1 feet and 11.87 inches) or 23.87 inches when traveling in air at 20°C (68°F).

The formula for the wavelenght is λ = c/f where:

  • c is the celerity (speed) of sound = 343.21 m/s or 1126.03 ft/s in air at 20°C (68°F).
  • f is the frequency = 566 Hz
which gives a wavelength λ of 0.61 meters, or 1.99 feet.

566 Hz Wavelength Depending on Temperature

The speed of sound in air depends on temperature. Here is how the wavelenght of a 566 Hz sound wave will vary according to temperature:

566 Hz Half Wavelength and Standing Waves

The half wavelength of a 566 Hz sound wave is 0.3 meters, 30.32 cm, 0.99 feet (0 feet and 11.94 inches) or 11.94 inches when travelling in air at 20°C (68°F).

Modes (or standing waves) will occur at 566 Hz in rooms where two opposing walls (axial mode), edges (tangential mode) or corners (oblique mode) are spaced by a distance d = nλ/2 where:

  • n is a natural (positive integer greater than or equal to 1)
  • λ is the 566 Hz wavelength = 0.61 meters, or 1.99 feet in air at 20°C (68°F).

566 Hz Standing Waves Distances

n Distance (m) Distance (ft)
10.300.99
20.611.99
30.912.98
41.213.98
51.524.97

We typically don't treat rooms for standing waves above 300 Hz.

Given the relatively small 566 Hz half wavelength, you can treat your room by using thick acoustic foam. This will absorb frequencies as low as 250 Hz, and all the way up to 20,000 Hz.

How To Convert 566 Hz To ms

A Hz (Hertz) is a cycle (or period) per second.

Because a 566 Hz wave will ocillate 566 times per second, we can find the time of a single cycle (or period) with the formula p = 1/f where:

  • f is the frequency of the wave = 566 Hz

The result will be expressed in seconds, so let's multiply by 1000 to get miliseconds:

1 / 566 Hz * 1000 = 1.77 ms.
