This 15 month effort included tasks to develop a software tool to aid in the collection of consistent anthropometric measurements from digitized ear canal shapes. The new Earshape Analysis Tool was used to process approximately 9000 digital earshape files (4500 left/right pairs). Output from the tool was tabulated to produce a deliverable dataset of all anatomical dimensions and summary statistics. The resultant dataset is expected to be useful for predicting the fit rate of a variety of insert hearing protector products.
