How Long Is a 616 Hz Wavelength?
A 616 Hz sound wave has a wavelength of 0.56 meters, 55.72 cm, 1.83 feet (1 feet and 9.94 inches) or 21.94 inches when traveling in air at 20°C (68°F).
The formula for the wavelenght is λ = c/f where:
cis the celerity (speed) of sound = 343.21 m/s or 1126.03 ft/s in air at 20°C (68°F).fis the frequency = 616 Hz
λ of 0.56 meters, or 1.83 feet.
616 Hz Wavelength Depending on Temperature
The speed of sound in air depends on temperature. Here is how the wavelenght of a 616 Hz sound wave will vary according to temperature:
| Temp (°C) | Temp (°F) | 616 Hz wavelength (cm) | 616 Hz wavelength (in) |
|---|---|---|---|
| -40 | -40 | 49.6887 | 19.5625 |
| -35 | -31 | 50.2187 | 19.7711 |
| -30 | -22 | 50.7431 | 19.9776 |
| -25 | -13 | 51.2622 | 20.1820 |
| -20 | -4 | 51.7761 | 20.3843 |
| -15 | 5 | 52.2849 | 20.5846 |
| -10 | 14 | 52.7888 | 20.7830 |
| -5 | 23 | 53.2880 | 20.9795 |
| 0 | 32 | 53.7825 | 21.1742 |
| 5 | 41 | 54.2725 | 21.3671 |
| 10 | 50 | 54.7581 | 21.5583 |
| 15 | 59 | 55.2395 | 21.7478 |
| 20 | 68 | 55.7167 | 21.9357 |
| 25 | 77 | 56.1898 | 22.1220 |
| 30 | 86 | 56.6590 | 22.3067 |
| 35 | 95 | 57.1243 | 22.4899 |
| 40 | 104 | 57.5859 | 22.6716 |
616 Hz Half Wavelength and Standing Waves
The half wavelength of a 616 Hz sound wave is 0.28 meters, 27.86 cm, 0.91 feet (0 feet and 10.97 inches) or 10.97 inches when travelling in air at 20°C (68°F).
Modes (or standing waves) will occur at 616 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:
nis a natural (positive integer greater than or equal to 1)λis the 616 Hz wavelength = 0.56 meters, or 1.83 feet in air at 20°C (68°F).
616 Hz Standing Waves Distances
| n | Distance (m) | Distance (ft) |
|---|---|---|
| 1 | 0.28 | 0.91 |
| 2 | 0.56 | 1.83 |
| 3 | 0.84 | 2.74 |
| 4 | 1.11 | 3.66 |
| 5 | 1.39 | 4.57 |
We typically don't treat rooms for standing waves above 300 Hz.
Given the relatively small 616 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 616 Hz To ms
A Hz (Hertz) is a cycle (or period) per second.
Because a 616 Hz wave will ocillate 616 times per second, we can find the time of a single cycle (or period) with the formula p = 1/f where:
fis the frequency of the wave = 616 Hz
The result will be expressed in seconds, so let's multiply by 1000 to get miliseconds:
1 / 616 Hz * 1000 = 1.62 ms.
