【摘要】：随着设计理论的不断细化和发展,声学成为用户体验研究中重要的一环,被广泛应用于建筑、产品和游戏设计等领域。声音体验的好坏不仅影响人的心情,还会对工作效率、睡眠质量产生潜移默化的作用。我国地域广阔,各地气候不一,空调产品越来越普及,很多人习惯在冬暖夏凉的空调房里工作、学习和休息。由于技术原因,空调工作时会不可避免地发出声音,这类声音会如何对人的感受产生影响,怎样设计空调的声音能让人感觉更加舒适成了空调产品用户体验中一个有待研究的问题。本文首先对不同年龄段用户的声音舒适度评价影响因素进行了研究。使用声学检测仪器对室内空调声源和声场的分布进行采集,并通过声学仿真软件模拟出不同空间的声学参数模型,进而研究各种声学客观参数对室内空调声音舒适度的影响。在空调声音舒适度主观影响因素的研究中,先对空调声音舒适度的需求进行了调研,基于需求点设计了空调声音舒适度评价量表,采用问卷调查的方式收集了用户对空调舒适度的主观评价信息,并与用户的基本情况和生理信息进行相关性分析,得到室内空调声音舒适度的影响因素。对空调声音舒适度客观影响因素的研究采用了声学参数采集仪器,收集了用户在工作和休息空间下空调的声音样本,分析获得了空调在不同空间下的声音频谱特征、响度、尖锐度、混响时间、语言清晰度及语言可懂度这些声学参数,对收集到的主客观因素进行相关性分析。使用ODEON声学仿真软件,设定模型参数和空调声源参数,模拟了工作和休息空间中的空调声学空间,分析了空间吸声体对声学空间参数的作用,以及房间装饰材料对室内空调声音舒适度的影响。本文通过主观问卷调查、客观实验测量和软件模拟仿真的方法,获得了用户对室内空调声音舒适度评价的一般规律,以及对声音舒适度的主客观影响因素。本文的研究成果将会对空调的声音设计带来一定参考价值,同时为不同空间场景下的声音体验研究提供一些思路。
[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.
