The Auditory Hazard Analysis Algorithm for Humans (AHAAH) calculates the risk to human hearing of impulse noises, such as gunfire or airbag deployment. It achieves this by modeling the effects of the sound pressure wave from the free field, through the middle ear, and into the inner ear. The output of the algorithm is the number of auditory risk units (ARUs) associated with exposure to the given impulse sound. ARUs ...
A patient's visual function has been routinely assessed by a visual acuity measurement, usually by means of a Snellen chart. More recently, visual acuity measurements have been extended to measure the progress of disease or the efficacy of therapeutic interventions. Thus, accurate and reproducible visual acuity measurements are needed. However, the intrinsic variability in line-by-line scoring is high because only 50%-80% of the letters in a line need be correctly ...
The brain rarely processes events of the physical world using signals from a single sensory modality. While the visual and auditory modalities are considered frequently in communication research, the tactile modality is considered the least as a possible mode of communication. In addition, previous studies of tactile sensitivity and solutions in utilizing the tactile modality have been focused on torso and limb locations. However, there are currently no tactile sensitivity ...
