ABSTRACT: It has been noted, in case of the apartments in collective form, the drainage
noise from cleaning of toilet causes many problems in the basement and adjacent rooms,
mainly hampering the pleasant housing environment. The problems are increasingly raised by
civil complaints with the public offices. Therefore, if the drainage noise generates when
wash out of toilet bowl is grasped how the characteristics change according to the sorts of
drainpipe, it is considered that the establishment of an effective sound insulation countermeasure
could be possible when a civil petition against the drainage noise of apartment house is
submitted hereafter. On such viewpoint, this study measured and analyzed the characteristics
of drainage noise per the type of drainage pipe, according to KS A ISO 1996-1～3, with the
horizontal branch pipe and riser pipes in the drainage noise experiment chamber which has
the characteristics of the anechoic room. In the result, the pipe type with excellent noise
reduction function. The result of this study is considered to become available as fundamental
data, to take actions on reduction of drainage noise of the ceiling piping method.
Key words: Drainage noise(배수소음), Sound pressure level(음압레벨), Frequency
