| The demand of nursing home is increasing as the family structure changing. And the old inside request both sound environment and mental characteristic which influence elderly people’s mental health, sleeping quality, etc. Thus, research on sound environment of nursing home and elderly people’s sound preference is essential. This paper did research on various factors that affect elderly people’s sound comfort degree with questionnaire, analyzed sound field distribution, simulated sound environment for main space of nursing home and studied various influence on sound environment with different materials.The paper collected elderly people’s requirement in nursing house by deep interview and sound preference scale. And subjective evaluation parameters and basic information of the old were learned from questionnaire. Also, factors that affect sound comfort in the environment like nursing home were collected with Correlation Analysis.Besides, the old people’s preference on sound sources was studied with Factor Analysis.Collecting sound samples were collected in main activity zone of nursing home with acoustic instrument. And sound spectrum characteristic, reverberation time,Articulation Index and Speech Intelligibility in different rooms were obtained by analyzing data. Based on the collected objective data, Correlation Analysis was conducted for subjective and objective parameters.Model of main activity zone inside nursing home was studied by setting materials and sound sources as well as simulating the sound environment in nursing home. Also,how changing on ceiling material, ground material, indoor greening and spatial sound absorber affects sound environment parameters was analyzed.This paper aims at obtaining elderly people’s sound preference and sound environment simulation with approaches of questionnaire, measurement and simulation.The findings in research can offer advice and favor for nursing home architect design and sound design for elderly people in the future. |
