Study On The Indoor Sound-environment Of Hospital Architecture In Xi'an

As the progress of our society, accelerated progress of urbanization and continuous expanding of architectural technology's research content, people are increasingly concerned with spiritual life. By that reason, indoor sound study is becoming popular, and the sound design is also expanding from theatrical building like theatre, music hall, and indoor stadium towards school building, residential housing and the most life-concerning hospital building. The noise pollution in the interior of hospital building, especially the clinical area, negatively impacts not only the physical and mental health of patients, but also work quality of medical personnel. Continuous progress of urbanization and rapid development of healthcare will inevitably make the noise pollution issue more obvious. In order to understand the impact level of noise pollution to patients and medical personnel, this paper, based on the analysis to structure characteristics of hospital building's indoor sound,studied the current noise pollution status of hospital building's indoor sound environment, through on-site measurement, questionnaire survey and analytical method of fuzzy mathematics.In this paper, the writer firstly consulted related document literatures. Based on these domestic and foreign studies, through on-site measurement to 3 general Grade A ClassⅢhospitals in Xi'an (Xi'an Children's Hospital,2nd Affiliated Hospital of Xi'an Jiaotong University&Xijing Hospital), this paper analyzed and studied all the factors and characteristics of the indoor environments. On this basis, the writer made a questionnaire and did a survey in those hospitals, let the respondents evaluate the hospitals' indoor sound environments in accordance with their feelings, and finally did statistics and analysis to the responses.For data analysis, this paper uses Comprehensive Evaluation Method of fuzzy mathematics to determine the respondents'general evaluation results to those hospitals' indoor acoustic environments. As the fact that many phenomena are caused by various factors in the objective world, so using the method of fuzzy mathematics can compute the percentage of respondents'subjective survey responses into a specific value to represent the sound ondition of those hospitals.Finally, after integrating the study results, this paper developed some methods and suggestions of planning & site-selection, architecture design and interior decoration of hospital building to improve their indoor sound environments. With this thesis, the writer hopes to contribute to better medical environment and the sustainable development of green hospital building design in our country.
