It seems like there might be a typo in your question. Sound cannot travel faster than sound itself because sound is the term used to describe the propagation of mechanical waves through a medium (such as air, water, or solid materials) to create an audible sensation in the human ear. The speed of sound depends on the properties of the medium through which it travels, such as density and elasticity.
In most cases, when people refer to sound traveling at a specific speed, they are talking about the speed of sound in air, which is approximately 343 meters per second (about 1,125 feet per second) at room temperature (around 20 degrees Celsius or 68 degrees Fahrenheit).
If you were referring to something else, please clarify, and I'll be happy to provide a more relevant answer.
