Abstract: The purpose of this report is to identify human use issues associated with using the Brain Acoustic Monitor. This report is the second of three reports examining human factors issues associated with technologies investigated for their potential to assist with identifying individuals who may have incurred a traumatic brain injury. The Brain Acoustic Monitor passively senses acoustic signals generated from the blood flow through an individual's brain and a reference point, such as the radial artery. If physiological alterations in blood flow due to damage to the cerebrovascular system occur, the corresponding acoustic changes should differ from those heard at the reference point, such as the radial artery. This assessment focuses on the training, setup, and operation of the equipment, identifying potential areas to consider for both users and developers of the equipment.
