1. A system for communicating input data and output data bi-directionally into and out of an environment, the system comprising,an external processor means outside the environment for transmitting the input data and for receiving the output data,an external modem means outside the environment and connected to the external processor means for modulating the input data into external data in signals and for demodulating external data out signals into the output data,a first transducer means outside the environment for transducing the external data in signals into input undulating pressure waves, the first transducer means is also for transducing output undulating pressure waves into the external data out signals,a solid medium means separating the external processor means and external modem means from the environment, the solid medium means is connected to the first transducer means, the solid medium means is for communicating the input undulating pressure waves encoded with the input data and for communicating the output undulating pressure waves encoded with the output data,a second transducer means connected to the solid medium means within the environment, the second transducer means for transducing the input undulating pressure waves into internal data in signals, the second transducer means is for transducing internal data out signals into the output undulating pressure waves,an internal modem means within the environment for modulating the output data into the internal data out signals and for demodulating the internal data in signals into the input data, andan internal processor means within the environment for receiving the input data and transmitting the output data through the internal modem means.
