Research On Sound Comfort Of Family Air Conditioners

The voice of the air conditioning work comfort level has become the important index of the air conditioning design experience,now people pay more and more attention to the voice of the living space and comfortable degree,not only affects the mental health of people,also affects the quality of people’s sleep physiological health,therefore,the voice of the research on indoor air conditioning comfort level is very important.This article mainly uses the questionnaire survey research methods,analysis the influence of different age paragraph the person to comfort evaluation factors.Air conditioning sound comfortable degree of subjective analysis,this article applies the method of investigation and research for the user demand for the comfort of air conditioning sound,according to the requirements on design of the air conditioning sound comfort evaluation questionnaire,with the method of questionnaire survey collected about user voice comfort subjective evaluation parameters for air conditioning and the basic characteristics of the user and physiological indicators.Using SPSS software for correlation analysis,the influence factors of comfort and comfort of indoor air conditioning were obtained.The objective analysis of the comfort assessment is by using acoustic parameters to collect the instruments,and collect the sound samples of the work and rest room air conditioning.Through data processing,to the voice of the air conditioner under different spatial spectrum characteristics,the degree of loudness,sharp and reverberation time and language clarity and intelligibility of these acoustic parameters,USES correlation analysis method to analyze the collection of the correlation between objective data and subjective evaluation.Using ODEON acoustic simulation software,the model parameters and the sound source parameters of the air-conditioner are set up,and the acoustic spatial model of the sound acoustic space is constructed.Through the analysis of ODEON software,the influence of the setting on acoustic space parameters was analyzed by the simulation analysis of the sound comfort and the room decoration material and the space absorbing sound.By subjective evaluation and objective in this paper the method of experimental measurement and simulation,obtained the objective law and the influence of indoor air conditioning sound evaluating sound comfort of subjective and objective factors.In this paper,the research results will provide future sound comfort indoor air conditioning design and suitable for different scenarios space air conditioning sound design offer some advice and help.
