Article 1 - “The effects of audio-visual factors on perceptions of environmental noise barrier performance”
Article 2 - “Audio-visual interaction and perceptual assessment of water features used over road traffic noise”

This article aims to investigate the intersensory perceptions of noise barrier performance in terms of the spectral characteristics of noise reduction combine with visual impression of five barrier types and to examine the audio-visual interaction and perception of water features used over road traffic noise including their semantic aural properties, as well as their categorization and evocation properties. This research conduct three different types of experiment which are audio-only experiment, visual-only experiment and audio-visual experiment. The result of the experiment revealed that noise reduction, particularly low frequency components, had a dominant effect on the perception of the noise-attenuating performance of barriers.
