Study On The Relationship Between Auditory Comfort And Spatial Correlation

With the rapid development of aging and the change of family structure,the demand for old-age institutions is increasing year by year.However,for a long time,in the field of architectural design and research,most of them remain in the residential function and barrier-free facilities of the elderly,while the spatial research on the auditory perception of the elderly is rarely carried out from the perspective of the main body of architectural use.Hearing is an important guarantee for the communication between the elderly and the outside world.The comfort of hearing and behavior is of great significance to the construction of the elderly's mental health and the improvement of the quality of life.From the perspective of the hearing comfort of the users of the old-age institution,this paper takes the typical space of the old-age institution-the living space and the dining space as the object of study.The relationship between auditory comfort and spatial "hearing distance"in residential space and the relationship between subjective comfort and sound pressure level and population density in dining space were taken as the main contents of the study.By means of the combination of human factor technique and subjective questionnaire,and the combination of subjective measurement and subjective questionnaire with statistical software,the experimental study on the two spaces was carried out to determine the comfort of the hearing of the elderly in the typical space of the old-age institution.The relationship between typical space and auditory comfort.First of all,this article combs the old-age building space in the acoustics aspect and the human factor technology "perception" the space aspect already had the achievement,On this basis,it summarizes the deficiency and development trend of the old-age building in acoustics and human perception.Secondly,four old-age institutions in Liaoning province are investigated after screening,and the main sound sources,auditory comfort behavior and problems found in the research process are summarized.On this basis,the main factors that affect the hearing comfort of the elderly in the typical space of the old-age institution are extracted,and the relationship between the typical space and the hearing comfort is put forward.Finally,in order to solve the above-mentioned problems,this paper takes Kang Le Center of Qinchun Garden,Kaiyuan,Liaoning Province as the experimental site to carry out experimental research on living space and dining space respectively.With the help of ErgoLAB human factor technology platform and subjective questionnaire,the living space is designed and simulated from the relationship between auditory comfort and spatial scale of,watching TV,behavior and "talking,behavior.A series of experiments were carried out on the relationship between subjective comfort in sound field and sound pressure level and population density through objective acoustic measurement and subjective questionnaire evaluation of dining space.
