When understanding and recalling spoken language, various complex processes take place in the brain. Certain circumstances can either impede or facilitate speech comprehension, e.g. visual stimuli such as lip movements or gestures. Although the field of cognitive psychology has already intensively studied short-term memory performance or listening effort in such situations, it mostly uses simple scenarios without plausible visual and auditory material. It is therefore possible that the performance of participants in such studies differs from reality. This work investigates…

Zhu: Examining the influence of visual stimuli on auditory selective attention in a virtual classroom

Auditory selective attention (ASA) is a common phenomenon which describes the ability to intentionally focus on a specific source of sound while ignoring other irrelevant sounds. Since in real life there are usually visual distractors in addition to auditory distractors, the effect of visual stimuli on ASA is also worth investigating. The purpose of this study was to explore a new paradigm to investigate the influence of visual stimuli on ASA. In addition, the experiment was carried out in a…

Chang: Sound transmission through ventilation openings in building facades

In tropical countries, air conditioning systems are widely used to improve indoor climate. In many cases, natural ventilation can also provide thermal comfort for users with less energy consumption and better air quality as long as the pollution outdoors is not too high. However, openings in the facades for natural ventilation decrease the sound insulation. Consequently, it is important to evaluate different facade designs in order to minimize the sound transmission through possible ventilation openings (VO).  This work is aimed…
