  • Speed of Sound in Air at 20°C: Factors & Calculation
    The speed of sound in air at 20°C is approximately 343 meters per second (m/s) or 767 miles per hour (mph).

    This is a commonly used value, but it's important to note that the speed of sound can vary slightly depending on factors like:

    * Humidity: Higher humidity slightly increases the speed of sound.

    * Altitude: Air density decreases at higher altitudes, slowing down the speed of sound.

    For more precise calculations, you can use the following formula:

    v = 331.5 + 0.606 * T

    Where:

    * v is the speed of sound in meters per second (m/s)

    * T is the temperature in degrees Celsius (°C)
