The speed of sound in air at room temperature (20°C) is approximately 343 meters per second (1,235 kilometers per hour, or 767 miles per hour).

The speed of sound in air is affected by several factors, including temperature, pressure, humidity, and wind speed.

• Temperature: The speed of sound increases as the temperature increases.

• Pressure: The speed of sound increases as the pressure increases.

• Humidity: The speed of sound decreases as the humidity increases.

• Wind speed: The speed of sound is affected by the wind speed and direction.

Sound of air

The sound of air is produced by the vibration of air molecules. When air molecules vibrate, they create sound waves. The speed of sound waves is determined by the density and elasticity of the medium through which they are traveling.

The sound of air can be heard by humans if it is loud enough. The human ear can detect sound waves with frequencies between 20 and 20,000 Hz.

The sound of air can also be heard by animals. Some animals, such as dogs, can hear sound waves with frequencies up to 45,000 Hz.
