Speed of Sound Equation:
| From: | To: |
The speed of sound in air is the distance traveled per unit time by a sound wave as it propagates through an air medium. It depends on temperature, humidity, and air pressure, with temperature being the most significant factor.
The calculator uses the standard speed of sound equation:
Where:
Explanation: The speed of sound increases by approximately 0.6 m/s for each degree Celsius increase in temperature. At 0°C, the speed is 331 m/s.
Details: Accurate speed of sound calculation is crucial for various applications including acoustic engineering, meteorology, aviation, sonar technology, and audio production. It helps in determining sound propagation characteristics and designing acoustic systems.
Tips: Enter the air temperature in degrees Celsius. The calculator will compute the speed of sound based on the standard formula. Temperature values can be positive or negative.
Q1: Why does temperature affect the speed of sound?
A: Temperature affects air density and the speed at which sound waves can propagate. Warmer air has lower density, allowing sound waves to travel faster.
Q2: What is the speed of sound at room temperature (20°C)?
A: At 20°C, the speed of sound is approximately 343 m/s (331 + 0.6 × 20 = 343 m/s).
Q3: Does humidity affect the speed of sound?
A: Yes, humidity slightly increases the speed of sound, but the effect is much smaller than that of temperature. The standard formula focuses on temperature as the primary factor.
Q4: How accurate is this calculation?
A: The formula provides a good approximation for most practical purposes. For precise scientific applications, more complex formulas accounting for humidity and pressure may be needed.
Q5: What is the speed of sound in other media?
A: Sound travels faster in liquids and solids than in gases. In water, it's about 1480 m/s; in steel, about 5100 m/s.
