AB  - Augmented Reality Audio is the technology in which virtual sound content is presented along with real sounds in a way that real and virtual sounds are indistinguishable. The final aim is to create an immersive experience for the listener. In order to achieve this effect over hearables, there are two critical steps: first, the real sounds must be perceived same as open ear reference. This often needs some additional processing since hearables modify the real sound spectrum, depending on their form factor and construction. Second, the rendered virtual sound must be perceptually indistinguishable from real sounds. This paper focuses on the first step of the process, with the final goal of perceptually reproducing real sounds same as open ear reference known as acoustic transparency. The techniques for achieving acoustic transparency have been referred to as hear-through processing. The paper describes the major components of hear-through technique, along with challenges and possible solutions from past studies. The relevant perceptual test paradigms which have been used for evaluation of hear-through in past studies for hearables are also listed.
