Don't know. I was wondering what the light of speed is when I saw your question

The speed of sound is a term used to describe the speed of sound waves passing through an elastic medium. The speed varies with the medium employed (for example, sound waves move faster through water than through air), as well as with the properties of the medium, especially temperature. The term is commonly used to refer specifically to the speed of sound in air. At sea level, at a temperature of 15 °C (59 °F) and under normal atmospheric conditions, the speed of sound is 340 m.s-1 (1225 km.h-1 or 761 mph).
The speed of sound is sometimes used in describing the nature of substances (see the article on sodium).
In conventional use and in scientific literature sound velocity, v, and sound speed, c, are used synonymously and should not be confused with sound particle velocity (also symbolized as v), which is the velocity of the individual particles.
The speed varies depending on atmospheric conditions; the most important factor is the temperature. Humidity has little effect on the speed of sound, nor does air pressure per se. (Pressure has no effect at all in an ideal gas approximation. This is because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out, leaving only the effect of temperature.) Sound usually travels more slowly with greater altitude, due to reduced temperature.

First of all, one would be quick to state that there lies no sound due to speed in a "frictionless environment." There, however, would be no "sound of speed" even in a normal environment. I'll explain.
Speed itself is a scalar, which means its existence is not representable in a visble world. It's a two dimensional measurement which takes one parameter of length and relates it to a second parameter of time (both on any number of scales, i.e., m/s, km/min, mi/hr, etc.) There is no sound to speed for it is simply a rate, just as there is no sound to a number for it is simply a quantity.

A sonic boom.
This assumes that speed is traveling faster than sound.

Why would you just not type "speed of sound" into google?

761 mph average speed through the atmosphere. The speed varies depending on how dense the material it is traveling through such as water, metal, air. If there is no material to travel through, then it does not travel at all such as in the vacuum of space.

For simple calculations it is 1000 ft.per second at sea level. Good approximation.
