834 Hz Wavelength

How Long Is a 834 Hz Wavelength?

A 834 Hz sound wave has a wavelength of 0.41 meters, 41.15 cm, 1.35 feet (1 feet and 4.2 inches) or 16.2 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 = 834 Hz
which gives a wavelength λ of 0.41 meters, or 1.35 feet.

834 Hz Wavelength Depending on Temperature

The speed of sound in air depends on temperature. Here is how the wavelenght of a 834 Hz sound wave will vary according to temperature:

834 Hz Half Wavelength and Standing Waves

The half wavelength of a 834 Hz sound wave is 0.21 meters, 20.58 cm, 0.68 feet (0 feet and 8.1 inches) or 8.1 inches when travelling in air at 20°C (68°F).

Modes (or standing waves) will occur at 834 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 834 Hz wavelength = 0.41 meters, or 1.35 feet in air at 20°C (68°F).

834 Hz Standing Waves Distances

n Distance (m) Distance (ft)
10.210.68
20.411.35
30.622.03
40.822.70
51.033.38

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

Given the relatively small 834 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 834 Hz To ms

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

Because a 834 Hz wave will ocillate 834 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 = 834 Hz

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

1 / 834 Hz * 1000 = 1.2 ms.
