The speed of sound changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary.
Formula for speed of sound c = 331 + 0.6 × ϑ
Ï‘ = temperature in degrees celsius.
At ϑ = 20°C we get a speed of sound c = 331 + 0.6 × 20 = 343 m/s.
1 °C change of temperature is equal to 60 cm/s change of speed of sound. When calculating the speed of sound forget the atmospheric pressure, but look accurately at the very important temperature. The speed of sound varies with altitude (height or elevation) only because of the changing temperature there!

How fast is the speed of sound km per hour?
The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.The speed of sound varies widely; in air, it is about 331 meters per second (multiply by 3.6 to get km/hour), in steel it can be about 5 times as fast.
What is the speed of voice per minute?
In common everyday speech, speed of sound refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance. Sound travels faster in liquids and non-porous solids than it does in air. It travels about 4.3 times faster in water (1,484 m/s), and nearly 15 times as fast in iron (5,120 m/s), than in air at 20 degrees Celsius.
How fast is mach1?
Mach 1 is one times the speed of sound, which equals the speed of sound, which is 768mph.
How fast does sound travel in metres per second?
This of coarse all depends on the altitude, the humidity, and the temperature of the air. At Sea level the speed of sound is roughly 344.4 meters per second. Check out the link to find more interesting info! Near room temperature, the speed of sound in air is 344.4 m/s.
How many mph is into the speed of sound?
In dry air (68F) the speed of sound is 343 meters per second
How is the speed of light and speed of sound related?
The speed of light is about 900,000 times as fast as the speed of sound in air.
How fast does sound travecl through air?
The speed of sound through dry air is 767 miles per hour.
What dictates how fast sound travels through air?
Essentially it is the density and temperature of the air which determines the speed of sound therein.
Can the speed of sound travel faster than the speed of light?
No. Light in vacuum is roughly 880 thousand timesas fast as sound in air.
How fast does sound travel in room temperature?
The speed of sound in air at 20°C is 343 m/s.
How fast through the speed of sound can a blackbird go?
A blackbird doesn't go "through the speed of sound", it moves through the air.
How fast is the speed of sound in knots?
The speed of sound in air is approximately 661 knots or 767 mph at sea level and at room temperature.
How fast is the sound barrier?
The speed of sound, which is when an object travels at the speed of sound, varies depending on the medium it is traveling through. In dry air at room temperature, the speed of sound is approximately 767 mph or 1,235 km/h. The speed of sound is also known as Mach 1.
What is the sound of air or water going very fast?
The sound of air or water moving very fast is usually described as a "whooshing" or "rushing" noise. This sound occurs due to the turbulence created by the high-speed movement of the air or water molecules.
Point a is 7.375' from point b how fast do sound travel?
It depends what the sound travels through. The speed of sound in air is 340 m /s.
What does the speed of sound measure?
The speed of sound measures how fast sound waves can travel through a medium, such as air, water, or solids. It is influenced by factors like temperature, density, and elasticity of the medium.
Which is faster the speed of sound or the speed of air?
The speed of sound depends on the air factors around it
