Abstract

In the past and even now, local governments have often relied on traditional sound control approach to resolve noise problems by lowering sound pressure level. However, this approach may not always be practical and cost effective. Alternative approaches have been explored by properly utilizing neighborhood sceneries or additional sound sources in neighborhood planning and building design to reduce the annoyance induced by road traffic noises. Past evidence suggested that greenery and water space were able to moderate noise annoyance, and water sound could be added to improve the acceptance of neighborhood sound environment. However, few studies investigated how the proportions of different types of environment features would affect sound perceptions. This study aims to reveal the effects of different proportions of environment features on the perception of combined water sounds and road traffic noises. A series of controlled experiments had been performed with a group of human participants in a laboratory setting mimicking a living room setting in Hong Kong. The relationships among neighborhood sceneries, water sound and noise annoyance were also revealed. The results of the study can help formulate a set of building design planning guidelines for effectively utilizing neighborhood sceneries and additional sound sources for providing better acoustic environment and promoting good well-being for modern city dwellers within limited community resources.
