Abstract
In thls paper we discuss the benefits to be gained from the use of one of building
forms, namely balconies, expressed in terms of reduction the sound pressure
level, in A-weighted scale, into the tall building fa~ade closed to roadway. The
results obtained from a 3 dimension numerical model using pyramid tracing
model developed by A. Farina. The geometry of the balcony with different
widths and an inclined ceiling with different inclined angles is tested. The results
indicate that the sound pressure level reduction, in A-weighted scale, obtained
from changing balcony depth varies from 4 dB (A) to 11 dB (A), and increases
with the increasing of floor level. While the inclined ceiling form is more
effective in the higher levels, where the sound pressure level, in A-weighted
scale, can be reduced by 6 dB (A). The inc
