• Description:
  Several evaluations were made by modified rhyme test (mrt) word lists transmitted through various simultations of the trapped-miner system being developed by the federal Bureau of Mines. The tests were performed in a "single blind" situation so that the evaluators would not be biased by knowing the characteristics of the system being simulated. A computer program was developed to provide a simulation of the electrical aspects of the communication system and to provide an evaluation by calculation of the articulation index (ai). The study indicates that communication through the presently proposed system will be somewhat unreliable at depths as great as 300 meters even with the system operating at maximum efficiency.
