 | Effects of continual 1-in-3 watches were evaluated over a 10-day period. Eight (of 39) men were found with observable threshold shifts. Dosimeter results showed that the typical noise exposure in terms of equivalent steady-state noise level in the space where most measurements were made averaged 89.9 dBA with a standard deviation of 4.5, whereas physical measures averaged 91.6 dBA with a standard deviation of 7.9. On a psychomotor four-choice serial ... |

|
 | Voice and visual interior communication (IC) requirements for new-construction aircraft carriers were developed from an extensive study conducted aboard deployed CVA's operating in the SIXTH and SEVENTH Fleets. The functional requirements which were derived provide balance between integration and separation of IC services required to support CVA operations. Nine IC services and associated terminal types were identified and defined to accomplish the above. In the process, the number of current ... |

|
| Experimental wire-free voice and visual communication systems were installed on three SERVPAC Combat Stores Ships. Follow-up studies were made on the human engineering, maintainability, and reliability features of the systems. On the basis of measurements and user comments, criteria were developed for commerical transceivers and CCTV to supplement standard fixed-wire IC during CONREP/VERTREP operations. The report summarizes four years of investigation and experimental trials with references to a series of ... |

|
| Traffic counts of dial-telephone usage were made on two CVA's operating in the Sixth Fleet, SARATOGA and JOHN F. KENNEDY, and two in the Seventh Fleet, RANGER and CONSTELLATION. The number of calls was analyzed by day, by 2-hour periods, by ship evolution, and by distribution of telephones among switchboards. The aircraft-maintenance switchboard was found to be inadequate in at least two respects: poor maintenance record and insufficient capacity. (Author) ... |
