What is the speed of sound in air?

The speed of sound in air is approximately 1100 feet per second (fps) at sea level and at standard atmospheric conditions. This value can vary slightly depending on factors such as temperature, humidity, and altitude; however, 1100 fps is a commonly accepted approximation for the speed under typical conditions. In contrast, the other figures provided are significantly higher and do not reflect the known acoustic properties of sound traveling through air. Understanding the speed of sound is crucial in applications such as aviation, acoustics, and oceanography, where sound propagation through different mediums is critical for accurate measurements and analyses.
