Abstract:
In Europe, the concept of quite facade (with traffic noise levels below 45 dB or
50 dB) has already been gotten a certain consensus, and been conveyed to the
legislation in some countries, but has not yet been discussed in China. On
account
of more closed housing blocks (courtyards) in Europe, it is might easy to obtain
quite facade. Whereas, It is may be difficult to achieve in China because of
parallel layout for multi-story row house (chiefly relate to the sunshine
duration
requirement). To make the question clearly, several residential areas in Dalian,
north of China, were selected to investigate the influence of building layout on
rear facade noise. According to the position relationship of residents and
roads,
three morphologies are investigated: paralleling, vertical, inclined. Each
morphology will be studied through the noise measurements in the field. In
addition, reduction of noise annoyance gained form quiet facade need further
research.
