Usually we talk about speed of sound. Speed is the rate of change of distance with time.
Velocity is a measure of both speed and direction of a moving object.
Velocity is the rate of change of displacement with time.
Speed is a distance an object goes, velocity is measurment of speed AND direction. Speed of sound at 20 degrees Celsius (68 degrees Fahrenheit) is 343 meters per second.
The accepted value of speed of sound in air is determined by the equation vT= (331.5 + 0.607T) m/s for the value T, put the temperature in. This will give you more accurate results. The temperature is important not the air pressure. The air pressure and the air density are proportional to each other at the same temperature. The speed of sound c depends on the temperature of air and not on the air pressure!
The humidity of air has some negligible effect on the speed of sound. The air pressure
and the density of air (air density) are proportional to each other at the same temperature.
It applies always p / Ï = constant. rho is the density Ï and p is the sound pressure.
Notice: The speed of sound is alike on a mountain top as well as at sea level with the same air temperature. Google is not correct (look at the following link)
http://www.google.com/search?q=speed+of+sound
Here is the answer of Google: "Speed of sound at sea level = 340.29 m/s".
This is no good answer, because they forgot to tell us the temperature,
and the atmospheric pressure "at sea level" has no sense. The speed of sound in air is determined by the air itself. It is not dependent upon the sound amplitude, frequency or wavelength.
Velocity of sound is not sound velocity.
Speed of sound has no effect on the particle velocity.
Call velocity of sound better speed of sound.
Call sound velocity better particle velocity.

By definition, acoustic impedance (AI) is derived by multiplying the density and velocity of each subsurface layer.

Sound waves are longitudinal waves in air. Velocity of sound waves in air at NTP = 332 m/s.
Sound waves are longitudinal waves in air. Velocity of sound waves in air at NTP = 332 m/s. Sound waves cannot pass through free space they essentially needs material medium for their propagation.

the medium will definitely effect the speeds of both speed and sound...check out the following articles from wikipedia for more information. speed of sound http://en.wikipedia.org/wiki/Speed_of_sound speed of light http://en.wikipedia.org/wiki/Speed_of_light

The wavelength is equal to the local velocity of sound divided by the frequency, As with light, there can be refraction when sound passes from one medium to another with a different sound velocity.

a sound wave transmitted at a frequency greater than 20,000 per second, or beyond the normal hearing range of humans. The specific wavelength is equal to the velocity divided by the frequency. this wave is generated from tranducers, tranducers converts the electrical energy into mechanical energy(wave), i.e ultrasonic wave.supersonic waves are those wave whose velocity are greater than the sound wave. Supersonic waves are generated by high explosives.
P waves (PRIMARY Waves) have the highest average velocity as they travel through the earth's materials.
Sound waves are an example of Longitudinal waves. They are waves in which the particle is displaced in a parallel direction to the direction of velocity of the wave. They are formed by a compression and expansion of particles.sound is an example for longitudinal wavesound waveLongitudinal waves, also known as "l-waves", are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave.
