๐ Sound Wavelength Calculator
Speed of sound is calculated using the dry-air approximation (331.3 + 0.606รtemperature).
Enter a frequency (Hz) and air temperature to calculate the sound wave's wavelength, using the standard approximation for the speed of sound in dry air (331.3 + 0.606 ร temperature). Useful as a reference for instrument tuning or acoustic design.
How to use
- Enter a frequency (Hz), or pick one of the preset buttons.
- Enter the air temperature (ยฐC).
- The wavelength and speed of sound are calculated automatically.
FAQ
What formula is used for the speed of sound?
The speed of sound in dry air is calculated with the widely used approximation "331.3 + 0.606 ร temperature (ยฐC)" (m/s) โ about 331.3 m/s at 0ยฐC and about 343 m/s at 20ยฐC.
How is the wavelength calculated?
Wavelength (m) = speed of sound (m/s) รท frequency (Hz) โ the basic relationship between wave speed, frequency, and wavelength.
Why does temperature affect wavelength?
The speed of sound changes with air temperature (higher temperature means faster molecular motion and a higher speed of sound), so for the same frequency, a different temperature gives a different wavelength.
