Abstract
1.Origin of the study
Due to high urbanization and rapid development of dwelling buildings in Taiwan, noise pollution becomes a general problem. This kind of noise is called indoor noise, it is composed of the noise from outdoor, neighborhood and equipments in buildings. Since the quantity of resident and equipments in buildings, therefore the noise from equipment and pipe used in water supply and drainage becomes the primary noise source in the indoor environment.
The noise of the equipment and pipe used in water supply and drainage is occurred by aging or error design system. If the consideration of noise and vibration isolation of the equipment and pipe does not be made, the indoor noise will be transmitted through air and structure and then it will affect the quality of the indoor sound environment. The investigation of the noise from equipment and pipe and the proposal of the improvement are recommended to raise the life quality in Taiwan.
2.Methods and procedure of the study
This study focused on the improvement in noise control from equipments and pipes used in water supply and drainage in dwellings. Measurements of noise from particular equipment used in water supply and drainage installations will be made in various dwellings. According to the analysis resolution of questionnaire on the indoor noise condition, and the result of measurements to find out the problem as well as the influence of flow rate and transmission path of the water on the noise distribution. This study will precede diagnosis and estimation of the noise measurement of equipment’s and pipes used in water supply and drainage in various dwellings and analyze the related data to obtain
the improvement. Proposal of the improvement that is based on this study can be applied to architecture design to create the better living environment.
3.Important findings
(1)This study referred the standard of Japan and European Union on equipment and pipe of water supply and drainage. We discussed about the measurement method, instrument setting and index calculation and established the standard of procedure of field measurements of noise of equipment and pipe of water supply and drainage.
(2)The results showed that the pipes outside the structure of congregate house was lower than the pipes inside the structure of row house on satisfaction and that related with the age of the houses.according the reaserch the noise value of the pipes outside the structure was higher than inside on PVC and it transmitted to above and under storeys by the connect ion of the pipes.we found the pipes of the water closet that obtained highest noise values in this study and provided the insulation method of the the water.
(3)This study found the questions and properties of the noise of the equipment and pipe of water supply and drainage in dwelling and referred the suggestion by presentation of the experts to provide the improvement methods of the equipment and pipe of water supply and drainage.
4.Suggestions
This study suggests studing the application feasibility of Chinese National Standards from ISO 16032(JIS A 1429) that conforms the trend of internationalization：For immediate strategies

Explanation: Chinese National Standards of acoustics included the measurement of material absorption, insulation of building and building element and sound power level but not provided the field measurement of equipment and pipe of water supply
and drainage. However, we suggest studing the application feasibility of Chinese National Standards from ISO 16032(JIS A 1429) that conforms the trend of internationalization.
This study suggests that the related organization can refer the methods and techniques of equipment and pipe of water supply and drainage：For immediate strategies
