Abstract: Noise is an inherent issue and is one of the major environmental hazards in urban cities. It originates from varied number of sources, including traffic, industrial and social activities. With the advancement of urban cities like Singapore, more buildings are built within close proximity to one another as land space depletes. Thus, this has led to traffic noise to be considered as a major concern for urban cities, as more buildings are constructed close to roads and be increasingly affected by the noise generated from the traffic. The adverse effects caused by noise pollution can be seen in the wellbeing of exposed human populations, as issues like annoyance and sleep disturbances, or even greater health issues like cardiovascular disease and hypertension can be induced by noise. Hence, there is a need to assess the acoustical performance of buildings and their ability in reducing the transmission of noise, to ensure the optimum oral comfort for the residents. The aim of this paper is to study the sound performance of the building by investigating on the variations of sound level with respect to the storey level, the sound attenuation in both indoor and outdoor environments of the building unit and to understand the relationship of the opening size of balcony doors and windows with sound level. Site measurements were conducted at the construction site of The Venue Residences and Shoppe and the data collected were analysed and processed in Microsoft Excel. From the generation of tables and graphs from the data collected, it was found that the sound pressure level increases with storey height whether in an indoor or outdoor environment. There were also significant sound level differences depending on the opening size of the balcony door or window, where higher sound level differences were observed on higher levels. Also, at low frequencies, higher sound pressure levels were measured and lower sound pressure levels are recorded at high frequencies. The effect of the acoustic barriers and ceilings were found to be positive, achieving substantial amounts of sound attenuation. However, there were limitations in this study which may have affected the accuracy of this study. Site and time constraints were the biggest limitations in conducting a more comprehensive study on the acoustic performance of the building and facades. Therefore, further experiments that eliminates these constraints should be carried out to conduct a more fair and accurate study.
