Speed of Sound Equation:
From: | To: |
The speed of sound equation calculates the velocity of sound waves in air based on temperature. The formula v = 331 + 0.6T provides an approximation of sound speed in dry air at standard atmospheric pressure.
The calculator uses the speed of sound equation:
Where:
Explanation: The speed of sound increases by approximately 0.6 m/s for each degree Celsius increase in temperature, starting from 331 m/s at 0°C.
Details: Accurate speed of sound calculation is important for various applications including acoustics, meteorology, aviation, sonar technology, and audio engineering.
Tips: Enter temperature in degrees Celsius. The calculator will compute the corresponding speed of sound in meters per second.
Q1: Why does sound travel faster in warmer air?
A: Sound travels faster in warmer air because the molecules move faster and can transmit sound vibrations more quickly.
Q2: What is the speed of sound at room temperature (20°C)?
A: Approximately 343 m/s (331 + 0.6 × 20 = 343 m/s).
Q3: Does humidity affect the speed of sound?
A: Yes, sound travels slightly faster in humid air than in dry air at the same temperature, though this equation provides a good approximation for most purposes.
Q4: How accurate is this formula?
A: This linear approximation is accurate for most everyday applications, though more complex equations exist for precise scientific calculations.
Q5: Does this formula work for other gases?
A: No, this specific formula is designed for dry air. Different gases have different molecular properties that affect sound propagation.
