Objective Metric Based Assessments for Efficient Evaluation of Auditory Situation Awareness Characteristics of Tactical Communications and Protective Systems (TCAPS) and Augmented Hearing Protective Devices (HPDs)
Abstract
The Virginia Tech Auditory Systems Laboratory (ASL) research effort for the DoD Hearing Center of Excellence was aimed at the development of an efficient, in- laboratory implementable test battery for auditory situation awareness (ASA) that objectively quantified the ASA performance afforded by various Tactical Communications and Protection Systems (hereafter, TCAPS) and augmented/advanced Hearing Protection Devices (hereafter, HPDs) used by the U.S. military. Specifically, each of the fundamental ASA task elements of Detection, Recognition/Identification, Localization, and COMmunications, hereafter termed "DRILCOM" ASA elements, is measured in the psychophysical test battery that was the primary deliverable from the research. The individual ASA elements scores from the test battery were kept separate so that performance on each element of ASA could be ascertained, and via statistical analysis, the individual elements sets of scores were applied to determine the DRILCOM test batterys effectiveness in measuring ASA afforded by each TCAPS or augmented HPD. The intent was that the test battery would ultimately be deployable in a military audiology clinical or other similar laboratory setting, and applicable to a wide variety of TCAPS as well as passive and augmented HPDs.
