  2. Click the "Calculate" button to compute the speed of sound in air.
  3. The calculator will display the result in meters per second (m/s).
  4. Click "Reset" to clear all inputs and start over.

Understanding the Formula

The speed of sound in air depends primarily on temperature. The formula used in this calculator is:

v = 331.3 + 0.606 × T

Where:

  • v = speed of sound in meters per second (m/s)
  • T = temperature in degrees Celsius (°C)

This formula is valid for temperatures between -40°C and 40°C. At 20°C (room temperature), the speed of sound is approximately 343 m/s.

Applications

The speed of sound calculation is useful in various fields:

  • Acoustics and sound engineering
  • Atmospheric science
  • Seismology
  • Navigation systems
  • Weather forecasting

Principle Explanation

The speed of sound in a medium depends on how quickly the medium's particles can transmit a disturbance. In air, warmer temperatures cause air molecules to move more rapidly, allowing sound waves to travel faster. This relationship is linear between -40°C and 40°C, as represented by the formula above.
