Evaluation of noise barriers for soundscape perception through laboratory experiments

Joo Young Hong , Hyung Suk Jang , Jin Yong Jeon

In the present study, soundscape qualities have been investigated for the different types of urban noise barriers. Field measurements were performed: the sound pressure levels in front and back of the barriers were measured and the pictures were taken. Accordingly, laboratory experiments were conducted to evaluate the soundscape quality when each noise barrier existed. The experiments consisted of three parts; 1) audio-only condition, 2) visual-only condition, and 3) audio-visual condition. As a result, the soundscape design elements for designing urban noise barriers were derived from the subjective preferences both in aesthetical and spectral characteristics of the noise barriers.
