The noise reduction technique using various sound barriers has been proved to be very effective in many highway construction projects. For example, in the planning phase of new road constructions, The Environmental Protection Department (EPD) of Hong Kong would work with other departments using different methods, including the buffer distance between the buildings and roads, sound barriers, and low-noise road surfaces, to improve the noise problems. However, the high cost of establishing and maintaining those setups makes the work tough for many counties in Taiwan, for they have very tight budget. Besides the budget, setting up sound barriers in crowded places is not feasible. In addition, the barriers may change drastically the appearance of a town or a city. With the increasing economical and business activities in a city, the increasing traffic noise has therefore become a crucial issue in the daily working and living environment. Most residential apartments in southern Taiwan are low-floor buildings, and their balconies are more or less functional in traffic noise reduction. Based on the theoretical model of noise transmission, this study analyzes the noise reduction patterns for different type balconies and also calculates the associated acoustic levels for the purpose of future balcony design.
