How fast is the speed of sound mph? Well, to know this you need to read this article. In this article, we have provided all the necessary information regarding the sound wave. Because, before knowing the speed of sound, you should know some basic information about the sound wave. The speed of sound mainly depends upon the temperature of the air through which the sound travels. Because in the cold medium the rate of molecules gets slower and it is more in the warm medium. Without further discussion let’s begin to know the speed of sound mph.
What Is Speed Of Sound Mph?
The speed of sound mph is 740 mph, here mph means miles per hour. When you closely observe the variation in the speed of sound, you will find that there is a strong effect of temperature and the medium through which the sound travels. At 0 degrees C, the speed of sound is about 740 mph and the speed of sound at 30 degrees C is 3313 mph.

It is not like that, the speed of sound is measured only in mph, you can also measure the speed of sound in different units. The speed of sound in different units is,
- The speed of sound in fps is 4,721 fps
- The speed of sound m/s is 331.29 m/s
- The speed of sound in km per hour is 1234.8 km per hour
- The speed of sound in mph 740 mph
The one thing you must know about the speed of sound is that the sound speed changes according to the medium through which sound travels. So, the speed of sound mph in air is 343 m/s, the speed of sound mph at sea level is 340 m/s, the speed of sound in space is 0 m/s, and the speed of sound mph in water is 1234.8 m/s. Sound waves can not travel in space, therefore, in space, the speed of sound is 0 m/s.
Now, you have all the basic information related to the speed of sound. Let’s know how to calculate it.
Calculate The Speed Of Sound
Calculation of the speed of sound just needs a formula that has already been derived by scientists. So, the formula to calculate the speed of sound is,
Speed = Distance/Time
In symbolic form,
S = D/T
Where,
S is the speed
D is the total distance covered by a sound wave
T is the time taken by a sound wave
To understand it in depth, let’s take an example of that.
Thunder is heard 3 seconds after the lightning is seen, then what will be the speed of sound? The distance was approximately 1035 m.
So, by using the formula of speed
Speed = Distance/Time
= 1035/3 = 345 m/s
So, the speed of sound is 345 m/s.
About Sound
A sound wave is a kind of pressure disturbance that travels through a medium by means of particle-to-particle interaction. For instance, while speaking, keep your hand on your throat, then you will experience a vibration. Why the vibration while speaking? Because, to travel sound waves, you need the movement of particles and these particles create vibration while moving. But in space, then no medium means no particle, therefore, the sound waves can not travel through space.
The speed of sound refers to how fast the disturbance is passed from particle to particle. While frequency refers to the number of vibrations per unit of time, speed refers to the distance that the disturbance travels per unit of time.

FAQ
How Fast Is Sound In Mph?
761.2 mph
Sound travels at about 344 m/s (761.2 mph). This is a bit faster than a civilian jet plane (a typical jet on its way from Chicago to New York travels at a peak speed of 550 mph). However, we have planes, mostly used by the military, that can equal and exceed the speed of sound.
Is The Speed Of Sound 1 Mile Per Second?
The speed of sound through the atmosphere is a constant that depends on the daily temperature. On a standard day at sea level static conditions, the speed of sound is about 760 mph, or 1100 feet/second.
How Fast Is The Fastest Sound?
(36 kilometers)
Scientists have discovered the fastest possible speed of sound, a zippy 22 miles (36 kilometers) per second. Sound waves move at different speeds in solids, liquids and gases, and within those states of matter — for instance, they travel faster in warmer liquids compared with colder ones.
Is 1000 Mph The Speed Of Sound?
The speed of sound varies depending on the temperature of the air through which the sound moves. On Earth, the speed of sound at sea level assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h).

Does Mach 1 Break The Sound Barrier?
Seventy-five years ago, on October 14, 1947, the Bell X-1 Glamorous Glennis, piloted by U.S. Air Force Captain Charles E. “Chuck” Yeager, became the first airplane to fly faster than the speed of sound (Mach 1). The experimental purpose-built aircraft reached 1,127 kilometers (700 miles) per hour (Mach 1.06).
Why Is It Illegal To Break The Sound Barrier?
Breaking the sound barrier leads to a sonic boom. And regulators have determined that people need to be protected from sonic booms. Planes produce sound waves when they travel. At under Mach 1, these waves propagate in front of a plane.
How Far Away Is A Sound If It Takes 10 Seconds To Reach You?
If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away.
Conclusion
Since you know the formula to calculate the speed of sound, you can calculate how much mph is the speed of sound. The speed of sound depends on frequency, time, and distance. It is the distance that a point on a wave travels per unit of time, it is often expressed in several units, as we have mentioned above. The slower a sound wave travels, the less distance it will cover in the same period of time. This means the speed of sound is directly proportional to the distance and inversely proportional to the time. This was all about the speed of sound mph.
