Whitaker, Leslie, Peters, Leslie J. and Mitchell, Jennifer (1992): Measuring Human Performance as a Function of Speech Communication Using the Close Combat Test Bed (CCTB) Facility. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 237-241.

“Auditory communication is critical for the successful completion of many tasks which require information be transmitted among crew members. The purpose of the present program of research is to determine the impact that speech communication has on performance of such tasks. As guidance for this program, a model of auditory communication has been developed. This model describes performance as a function of three factors: transmission, linguistic, and individual. The model assumes that variables affecting these three factors alter the level of auditory workload and task performance is a consequence of this workload (Peters, 1991). The present paper describes the effects of two transmission factors: speech intelligibility and communication structure. Speech intelligibility was measured using the Modified Rhymes Test. Communication structure was defined as command, interrogative, and discussion levels. Three studies have been completed in this research program. The focus of the present paper is the most recent study, completed at the Ft. Knox Close Combat Test Bed, an M1A1 tank simulator facility. After describing the results of this study, the results of all three studies are reviewed and found to be consistent with the auditory-performance model proposed by the authors.”
