Most current hearing research laboratories and hearing aid evaluation setups are not sufficient to simulate real-life situations and to evaluate future generations of hearing aids that might include gaze information and brain signals. Thus, new methodologies and technologies might need to be implemented in hearing laboratories and clinics in order to generate audiovisual realistic testing environments. The aim of this work is to provide a comprehensive review of the current available approaches and future directions to create audiovisual realistic immersive simulations for hearing research. Additionally, we present the technologies and use cases of our laboratory, as well as the pros and cons of such technologies: From creating 3D virtual simulations with computer graphics and virtual acoustic simulations, to 360º videos and Ambisonic recordings.
