271 Hz Wavelength

How Long Is a 271 Hz Wavelength?

A 271 Hz sound wave has a wavelength of 1.27 meters, 126.65 cm, 4.16 feet (4 feet and 1.86 inches) or 49.86 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 = 271 Hz
which gives a wavelength λ of 1.27 meters, or 4.16 feet.

271 Hz Wavelength Depending on Temperature

The speed of sound in air depends on temperature. Here is how the wavelenght of a 271 Hz sound wave will vary according to temperature:

271 Hz Half Wavelength and Standing Waves

The half wavelength of a 271 Hz sound wave is 0.63 meters, 63.32 cm, 2.08 feet (2 feet and 0.93 inches) or 24.93 inches when travelling in air at 20°C (68°F).

Modes (or standing waves) will occur at 271 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 271 Hz wavelength = 1.27 meters, or 4.16 feet in air at 20°C (68°F).

Given the relatively large 271 Hz half wavelength, standing waves will occur at that frequency in small listening rooms.

You can try to minimze the room modes at 271 Hz by trying different speaker positions, listening positions or by placing bass traps. These can absorb frequencies as low as 63 Hz.

How To Convert 271 Hz To ms

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

Because a 271 Hz wave will ocillate 271 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 = 271 Hz

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

1 / 271 Hz * 1000 = 3.69 ms.
