DIDS INTELLIGIBILITY STUDY: EFFECTS OF ATMOSPHERIC NOISE,
Abstract
The report gives the results of laboratory experiments with an eight-man listening panel to determine the minimum signal-to-noise ratio required for reception of intelligible voice warning messages embedded in the atmospheric noise environment of the United States. These results were applied to the performance model of the DIDS Distribution Subsystem using a new analytical interpretation (developed for the study) of the statistical noise parameters specified by the International Radio Consultative Committee. The results fill a gap in existing DIDS feasibility estimates and allow more precise definition of the effectiveness requirements. (Author)
