The purpose of this study was to explore the effects of high fidelity digital voice transmission, some aspects of information processing and the effect of short-term memory and long-term memory on one-way verbal communication. The experiment consisted of one realistic scenario with each of the twenty-four subjects involved recording on paper each of the sixteen Automatic Terminal Information Service (ATIS) messages that they heard. Each subject heard each message one time, and the listening devices used were changed after four messages. The ATIS message consists of eleven hem groups of information. The results were viewed in group, number, and word errors. The largest error was the error of omission, and the most errors were found in message item 11 of the remarks section. The lengthy and complex remarks section overtaxed the capacity of the short term memory and resulted in large numbers of omission errors.
