Interactive real-time auralization of airborne sound insulation in buildings

Sound insulation auralization can be used as valuable tool to study the perceptual aspects of sound transmission in built environments for assessment noise effects on people. It may help further develop guidelines building constructions. One advanced goal real-time is appropriately reproduce condition human perception and cognitive performance dynamic interactive situations. These depend kind signal (i.e. speech, music, traffic noise, etc.) context. This paper introduces a model. The filters are constructed virtual buildings with respect complex propagation indoor outdoor sources. approach considers source room field direct diffuse components along directivity position. transfer functions subdivided into patches from receiver room, which also covers composite elements, thus providing more detail actual Furthermore, receiving acoustics includes reverberation based its mean free path, absorption binaural between radiating walls elements listener. exact model agrees reasonably well ISO standard theory) under settings. shown that significantly influences transmitted energies via depending position source. proposed method validated general scheme details specific situations especially cases where simplified fails. capable Virtual Reality (VR) systems, opens new opportunities psychoacoustics research human.
