There are two relatively simple methods for measuring the speed of sound, both of which involve timing echoes:
Both methods can be found in more detail at http://www.instructables.com -
Shoot a canon far away. Look at the flash the cannon makes and start a stop watch when you see the flash. Stop the stop watch, when you hear the bang. The time of the speed of sound is the distance from the canon divided by the time you measured.
Speed v = distance d / time t.
There is no need to "work out" the speed of sound; that was established very long ago. In dry air at 20 °C (68 °F), the speed of sound is 343 meters per second (1,125 ft/s). This equates to 1,236 kilometers per hour (768 mph), or about one kilometre in three seconds and about one mile in five seconds.
If you stand a known distance from a wall e.g 100m, and make a short sharp sound e.g a really loud finger snap you can hear an echo. With practice you can then time your snaps in time with the echo and the next and so on. Simply timing how long it look for say 30 snaps with a stopwatch, you can use the equation speed=distance/time to get the speed.
One way to measure the speed of sound in air is to measure the time taken by a sound to echo back from a distant object. The reflecting surface, which should be smooth and at right angles to you, should be at a measured distance (about 50 metres) away so that the interval between the sound and its echo is perceptible. However, to avoid errors due to your response times you should use electronic equipment to measure the time interval.
Then, if the distance to the reflecting surface is d metres and the ech arrives t seconds after the sound is made, v = 2s/t metres/second.

The speed of sound in air is 343 m/s at 20 degrees .5
In general, the speed of sound c is given by
c = \sqrt{\frac{C}{\rho}}
where
C is a coefficient of stiffness
ρ is the density

sound waves
The speed of sound in a solid is faster than the speed of sound in air.
The speed of light is much greater than the speed of sound.
what is the speed of sound in ntp
Hertz is used to measure sound frequency (how high or low the sound is). Decibels are used to measure how loud or soft a sound is.
sound waves
There are a few different ways you could measure the speed of sound in water and air. You could record the amount of time it takes a sound to be heard from the source to the destination for example.
-- Measure the distance between two points.-- Measure the time it takes the jet to fly from one point to the other one.-- The speed of the jet between the two points is(the distance between them)/(the time it takes to fly from one to the other)
A sonic anemometer uses sound to measure wind speed. It sends a sound signal from a fixed transmitter to a fixed receiver, and by measuring the time it takes for the sound to arrive, can compute the speed of sound. Wind speed will increase or decrease the speed of sound depending on whether it is a tail wind or a head wind. By measuring the speed of sound in both directions the wind speed along that axis can be calculated from the difference of the two measurements. A two axis or three axis instrument can measure total wind speed.
Roughly speaking, light moves about a million times faster than sound in air.
The speed of sound depends on the medium through which the sound waves travel - it is not a constant. So the first requirement would be to measure the speed of sound. Then simply take the square root of the numerical value and make sure the measurement units are "square-rooted" as well.
Simply by measuring the time it takes for the sonar 'ping' to return to the device that sent it. The speed of sound is constant - and dividing the time by the speed of sound gives the distance !
The speed of sound in a solid is faster than the speed of sound in air.
The speed of sound in steel is faster than the speed of sound in air.
If you try to measure it its still the speed of light : 186,000 miles per second PLUS about 0.2 miles per second.
No, the speed of sound is faster in solids.
This is not a saying, it's a fact. The speed of light is faster than the speed of sound, so the further away the lightning is the longer the gap is between the light reaching you and the sound reaching you.
