Study On Sound Quality Experience Design Of Range Hood For Audio-visual Interaction

Nowadays,noise became the problem that cannot ignore,the kitchen regards the very important space in the family as,its use frequency is far prep above other bedroom.As economic development and the change of people’s way of life,the kitchen gradually becomes intelligent and integrated life service system.People interact with kitchen electricity in the kitchen through visual,auditory and other sensory channels.Among them,auditory interaction is an important part of user experience,the range hood noise is the main source of non-voice sound signal,its sound quality is easy to cause users to varying degrees of annoyance,disgust and other negative emotions,so as to reduce the user’s auditory experience.Although the range hood on market at present has greatly improved the quality of sound,but how to promote experience better is the pursuit goal of people all the time.This paper will comprehensively analyze the auditory properties of sound in kitchen electric appliances,especially the range hood sound,to understand users’ feelings and demands for audiovisual interaction,so that sound can play an important role in product design.Combined with the multi-modal natural interaction design research project of the intelligent kitchen integrated system,this study focuses on the analysis and evaluation of noise quality in the kitchen.Taking the noise of range hood as the research object,through analyzing its sound quality,using the masking effect of the sound in psychoacoustics,the subjective and objective evaluation of the sound is carried out from the perspective of human sensibility,and a new audio-visual experience way is proposed to meet the needs of users for the sound design of range hood.The main research contents are as follows:Firstly,the research and summary of the acoustic quality evaluation of audiovisual interaction are carried out,the user experience and evaluation of acoustic quality are analyzed,and the research process of acoustic experience is proposed to lay a foundation for subsequent research.In the experimental stage,the noise sensitivity demand and related factors of range hood are explored from both subjective and objective aspects.The masking effect of psychoacoustics was introduced into the audio-visual interaction design of range hood,and the method of reducing noise annoyance was proposed.Selecting natural acoustic noise masking oil absorption as sound auditory experimental samples,using SD scale method,paired comparison,facial expression analysis method with the combination of subjective and objective analysis method,through the experimental analysis of different samples of the user’s subjective annoyance and emotions activate arrangement,to gain the natural sound kind of masking oil absorption of noise quality optimal sample,And based on this conclusion combined with the consistency of audiovisual integration in the design of the application to verify the results,improve the product audiovisual system,so as to enhance the user’s sense of experience,to achieve the purpose of reducing annoyance.Based on the improvement of sound quality experience of range hood,through the analysis of noise problems,this paper studies how to make use of the characteristics of integration and consistency of audio-visual dual-channel emotional information in product interaction design to help users reduce their annoyance and promote good use experience.It makes the audio-visual interaction design natural and vivid,closer to users and better sound quality,and provides reference methods and innovative ideas for the interaction design of range hood.Future lampblack machine design people will consider noise size and quality more,the hope can fall in comfortable audio-visual environment,get comprehensive sensory experience,alleviate the anxiety on mood and uneasiness.
