In everyday life, the acoustic signal that reaches our ears is a combination of multiple sound sources. Despite this complexity, normal hearing listeners are able to separate the acoustic mixture and focus on individual sound sources. This process of segregation includes both bottom-up and top-down processes in the auditory system. In his PhD project, Simon Krogholt Christiansen investigated these bottom-up processes using both behavioural experiments and computer modelling.
