Human Systems IAC was asked to determine the existence of a measure designed specifically to assess auditory workload. Should no such measure be found, Human Systems IAC was then required to give recommendations for a research plan to develop such an auditory workload measure. Human Systems IAC performed an in-depth literature search and consulted several subject matter experts to determine the existence of an auditory workload measure. Based on the available information, Human Systems IAC concluded that no auditory workload metric was available. As a result, recommendations were made for a new metric. Utilizing suggestions from related literature, it was recommended that an existing test, the NASA Task Load Index TLX, be adapted to assess auditory workload. Suggestions were provided for this adaptation. Considerations for experimental design and selection of independent variables were also included in the methodology provided.
