Why it's Gaining Attention in the US
So, how does sound travel through the air, exactly? The process begins with a disturbance, such as a vibrating object or a compressed air molecule. As the disturbance spreads, it creates a series of pressure waves that propagate through the air. These pressure waves, or sound waves, are a combination of compressions and rarefactions that travel at a speed of approximately 768 miles per hour (mph) at sea level in dry air at a temperature of 68°F (20°C). This speed, known as the speed of sound, is dependent on several factors, including temperature, humidity, and air pressure.
