Summary:
Annoyance caused by environmental noise intruding the private dwelling and perception of the sonic environment in public spaces have in common that they critically depend on the sounds that are being noticed. During everyday activities, the probability of noticing a sound in the complex sonic environment is proportional to how much this sound stands out, how salient it is. Based on a thorough review of human auditory processing, scene analysis, and attention, a computational model has been proposed that allows to identify salient sounds in a complex environment. The tonotopic model possesses a unique capability to trace amplitude modulations and phase modulations, which are features that the human auditory system is highly sensitive for. The model is validated by exploring its response to sound environments with known annoying characteristics such as short rise times and impulses and results are contrasted against loudness.
