室內(nèi)空調(diào)聲音舒適度研究
[Abstract]:With the development of design theory, acoustics has become an important part of user experience research, and has been widely used in architecture, product and game design. Sound experience not only affects people's mood, but also exerts a subtle effect on work efficiency and sleep quality. Our country has a wide area, different climate, air conditioning products more and more popular, many people used to work, study and rest in the cool air conditioning room in winter and summer. For technical reasons, it is inevitable that air conditioners will make sounds when they work, and how such sounds can have an impact on people's feelings. How to design the sound of air conditioning to make people feel more comfortable has become a problem to be studied in the user experience of air conditioning products. In this paper, the factors influencing the sound comfort evaluation of users of different age groups were studied. The acoustic measurement instrument is used to collect the sound source and sound field of indoor air conditioning, and the acoustic parameter models of different space are simulated by acoustic simulation software, and the influence of various acoustic objective parameters on the sound comfort of indoor air conditioning is studied. In the research of subjective influencing factors of air conditioning sound comfort, the demand of air conditioning sound comfort is investigated firstly, and the air conditioning sound comfort evaluation scale is designed based on the demand point. The subjective evaluation information of air conditioning comfort degree was collected by questionnaire, and the correlation analysis was carried out with the basic situation and physiological information of users, and the influencing factors of indoor air conditioning sound comfort degree were obtained. The objective influencing factors of air conditioning sound comfort were studied by means of acoustic parameter acquisition instrument. The sound samples of air conditioning in work and rest space were collected, and the sound spectrum characteristics and loudness of air conditioning in different space were analyzed and obtained. Acoustical parameters such as sharpness reverberation time articulation and intelligibility are analyzed. Using ODEON acoustic simulation software, the model parameters and the air conditioning sound source parameters are set, and the air conditioning acoustic space in the working and resting space is simulated, and the effect of the space sound absorber on the acoustic space parameters is analyzed. And the effect of room decoration material on the sound comfort of indoor air conditioning. By means of subjective questionnaire survey, objective measurement and software simulation, the general rules of users' evaluation of indoor air conditioning sound comfort and the subjective and objective factors affecting the sound comfort degree are obtained in this paper. The research results of this paper will bring some reference value to the sound design of air conditioning and provide some ideas for the study of sound experience in different space scenes.
