# How Many Mph Does Sound Travel?

The speed of sound may be defined as the distance that a sound wave travels in a given amount of time when it is transmitted through a material that is elastic.At a temperature of 20 degrees Celsius (68 degrees Fahrenheit), the speed of sound in air is approximately 343 meters per second (1,125 feet per second; 1,235 kilometers per hour; 767 miles per hour; 667 kilonewtons), which is equal to one kilometer in 2.9 seconds or one mile in 4.7 seconds.

The human brain generates the experience of sound in response to sensory information received from the middle and inner ears. The speed of sound as it travels through the atmosphere is a constant that varies according to the current temperature. When circumstances are static at sea level, the speed of sound is around 760 miles per hour, which translates to 1100 feet per second.

## What is the speed of sound through air?

The distance that a sound wave travels through an elastic medium in one second is known as the speed of sound. At a temperature of 20 degrees Celsius, the speed of sound in air is equal to 343 meters per second, which is equivalent to approximately 767 miles per hour.

## How long does it take sound to travel 1 km?

As can be seen, the speed of sound varies depending on the temperature and the humidity; nevertheless, if you want a round number, then something like 350 meters per second and 1,200 feet per second are fair quantities to use. Clearly, the speed of sound varies. Therefore, sound can reach one kilometer in around three seconds and one mile in approximately five seconds.

## How do you calculate the speed of sound in miles per hour?

The speed, expressed in kilometers per hour, is calculated by multiplying the speed of sound by 767.269148. Using the technique shown above, below is an illustration of how to convert five miles per hour into the speed of sound. 5, multiplied by 767.269148, equals 3,836.345741 miles per hour.

## Does sound move a mile a second?

Sound travels at a speed of around 1,129 feet (344 meters) per second in air at a temperature of 70 degrees Fahrenheit (22.2 degrees Celsius). This is roughly similar to traveling one-fifth of a mile in one second, or traveling one mile in five seconds (or one kilometer in about three seconds).

## What is the speed of sound of air?

The speed at which sound waves travel through a variety of materials is referred to as the speed of sound. In particular, the contemporary figure for the speed of sound in dry air at a temperature of 0 degrees Celsius (32 degrees Fahrenheit) is 331.29 meters per second (1,086.9 feet per second).

## How fast in mph is 10 times the speed of sound?

At this time, the scramjet engine of the airplane would start up and propel the aircraft to an incredible Mach 10 speed, which is just less than 8,000 miles per hour (12,348 kilometers per hour).

## Can sound travel faster than the speed of sound?

Over the speed of sound? Due to the fact that the speed of sound has a fixed value (which, in reality, is not all that high), it is possible, at least in theory, for an item that creates that sound to catch up with its own ″noise″ and even travel faster than before.

## When sound travels faster higher above the ground?

Since sound waves move at a quicker speed through warmer air, the sound waves are refracted upward and away from the ground.Temperature inversions are caused by a variety of atmospheric variables, and they manifest themselves as an increase in air temperature with increasing altitude.Because of this, part of the sound energy that originates from a source that is close to the ground is refracted back toward the ground.

## How long does it take sound to travel 2 miles?

As can be seen, the speed of sound varies depending on the temperature and the humidity; nevertheless, if you want a round number, then something like 350 meters per second and 1,200 feet per second are fair quantities to use. Clearly, the speed of sound varies. Therefore, sound can reach one kilometer in around three seconds and one mile in approximately five seconds.

## How many times faster is light than sound?

The speed of light while it is moving in a vacuum is the one that is used as the standard meter. This constant, also known as c, travels at approximately one million times the speed of sound in air and has a value of around 186,000 miles per second.

## How fast is the speed of sound underwater?

Sound travels more quickly through water than it does through air. Under normal circumstances, the speed of sound in air is around 343 meters per second, but the speed of sound in water is approximately 1,480 meters per second. Standard sound is, at its most fundamental level, a compression wave that travels through a material.

## How fast is the speed of dark?

The speed of darkness is equal to the speed of light. To be more precise, darkness does not exist apart from light as its own distinct physical entity; rather, darkness is just the lack of light.

## At what altitude does sound stop?

The high-pitched, high-frequency sound waves with short wavelengths are the first to dissipate as one ascends higher and higher into the atmosphere. Even the lowest frequency tone that a human being is capable of hearing (about 20 Hz) cannot be conveyed once you reach a certain height, which is around 160 kilometers (99 miles) above sea level.

## Are shock waves faster than sound?

Shock waves in particular move faster than sound waves, and their speed increases as the amplitude is raised; however, the intensity of a shock wave also decreases faster than does that of a sound wave. This is due to the fact that some of the energy of the shock wave is used up to heat the medium in which it travels, which causes the intensity of the shock wave to decrease.

## Who fast is Mach 1?

The Austrian scientist Ernst Mach is honored with the naming of the ″Mach Number.″ The speed of sound, sometimes known as Mach 1, is equal to roughly 760 miles per hour as measured at sea level.When an airplane is traveling at speeds that are less than Mach 1, it is said to be traveling at subsonic speeds.When an airplane is traveling at speeds that are higher than Mach 1, it is said to be traveling at supersonic speeds.

## Is Mach 3 3 times the speed of sound?

The aircraft, which would have triangular delta wings, would have the capability of traveling at Mach 3, which is equivalent to 3704 kilometers per hour or three times the speed of sound.

## How long does sound take to travel 12 miles?
