In the deep ocean at mid- latitudes, the slowest sound speed occurs at a depth of about 800 to 1000 meters. The speed of sound in a metal is 1000 m s-1. Frequency doesn't only determine how we feel or perceive a sound but also determines if we can sense it. also please specify the pitch and the volume of your sound. For me, I have family across the U.S., so family visits are usually 900-1400 miles. The formula for average speed, also called average velocity in physics and engineering, is: where v is the velocity, d is the distance, and t is the time, so you can read it as Speed = Distance / Time. Temperature is another crucial factor in the speed of sound in fluids, as it affects bulk modulus and density. In this blog post, we will explore the science of acoustics and how sound travels. How does sound travel long distances? Now that we know how sound propagates and how its speed depends on the medium, lets take a look at how to calculate how far it will travel between two points. In air, sound travels about 1000 feet If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away. In this article we will answer how sound travels and how to calculate how far it travels in different scenarios. Sounds can propagate through solids better than they can propagate through air because their density/stiffness are greater (this means that sound travels faster). In dry air at 20 C (68 F), the speed of sound is 343.2 metres per second (1,126 ft/s; 1,236 km/h; 768 mph; 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s. In common everyday speech, speed of sound refers to the speed of sound waves in air. Flood Safety If the total distance travelled was 500 miles and the time it took you was 5 hours, then your average speed was 500 / 5 = 100 miles per hour (mph). There are two main kinds of waves: mechanical waves and electromagnetic waves. All NOAA, Two winter storms are impacting the country, one across the northeast corridor and the other approaching the west coast.
