Speed of Sound Formula:
From: | To: |
Definition: This calculator estimates the speed of sound in air based on the current temperature.
Purpose: It helps physicists, engineers, and audio professionals understand how temperature affects sound propagation.
The calculator uses the formula:
Where:
Explanation: The speed of sound in air increases by approximately 0.6 m/s for every degree Celsius increase in temperature, starting from 331 m/s at 0°C.
Details: Understanding sound speed is crucial for acoustic design, sonar systems, audio engineering, and atmospheric studies.
Tips: Simply enter the current air temperature in degrees Celsius. The calculator works for typical atmospheric conditions.
Q1: Why does temperature affect sound speed?
A: Warmer air has faster-moving molecules that transmit sound vibrations more quickly.
Q2: Is humidity a factor?
A: This simplified formula doesn't account for humidity, which has a minor effect (about 0.1% increase per 10% humidity).
Q3: What's the speed of sound at room temperature (20°C)?
A: Approximately 343 m/s (331 + 0.6 × 20 = 343).
Q4: Does this work for extreme temperatures?
A: The formula is accurate for typical atmospheric conditions (-20°C to +40°C).
Q5: How does altitude affect the result?
A: This formula assumes sea level pressure. At higher altitudes, the speed would be slightly different due to pressure changes.
