He conducted experiments by timing the difference between the sight and sound of a gun being fired. He used echo and reverberation methods to estimate the speed of sound in air to be around 428 m/s.

Galileo was one of the first to suggest that sound travels at a finite speed. He theorized that the speed of sound could be calculated by timing the delay between the appearance of a distant flash of gunfire and when the sound was heard.

Pythagoras noted the relationship between string length and pitch, while Aristotle posited that sound travels through the air by the motion of air particles.
