Nowadays, a large portion of the elder population suffers from hearing loss, negatively impacting the life quality. Therefore, hearing-impaired older adults are often fitted with hearing aids (HAs). However, many complain of insufficient hearing support, especially in complex listening environments. One cause can be found in the standard audiometric tests used to assess HAs performance, which do not account for the actual conditions in which the listening mechanism is activated in real life, as the complexity of the acoustical scenarios and the influence of other senses like the visual component. Thus, to perform ecological listening tests, i.e., tests involving everyday-life conditions, recently, Virtual Reality (VR) systems have been used to reproduce listening tests inside virtual sound environments, representing most frequently attended environments (FAEs) with multiple varying noise sources (e.g.
