The underground information transmission can be summed up for wired transmission method and wireless transmission method But, traditional cable transmission has many drawbacks, including annulus test method, bundled test method, and optical transmission method. Therefore, wireless transmission technology and methods become a focus for researchers. Acoustic telemetry method has the advantages of low cost, simple method of operation, called a ideal transmission. In this paper, we reserch wireless acoustic telemetry underground instrument according to the theory of acoustic propagati
