Study on Differences between Individualized and Non-Individualized Hear-Through Equalization for Natural Augmented Listening

Document Thumbnail

Hear-through (HT) equalization (EQ) is imperative to achieve acoustical transparency for Augmented Reality headphones. Our previous study has shown that closed back headphones can be used with directional hear-through filters derived using adaptive algorithms to emulate reference case of open ear listening. The objective results and perceptual studies showed close match of ideal equalized signal with this reference signal. However, previous study only evaluated the performance of HT filters based on dummy head measurements, where it was assumed that individualized measurements are required for ideal hear-through. The effect of non-individualized HT filters was not clear and remained to be investigated. The aim of this study is to evaluate the differences in using individualized and non-individualized HT filters. It is hypothesized that a major difference exists because of the individual pinnae cues. The objective and subjective results suggest that there are perceptually distinguishable differences in timbre and high errors in localization for non-individualized HT EQ as compared to individualized HT EQ.
