The decline of the hearing level is a common problem faced by most old people, which not only affects normal communication and daily activities but also affects the mental health of the elderly. Aim: To explores the correlation between hearing comfort and conversation distance of elderly people , this study selects a nursing home in northeastern China to observe and interview the daily activities of the elderly in the living space, record the daily behaviors under auditory dependence, and evaluate the hearing level of the elderly, which is divided into two categories: good listening and weak listening. Method: This paper takes conversational behavior as an example and explores it by human factors experiment. The experiment randomly selected two groups of the elderly with good and weak hearing level as experimental subjects, each group consisting of 30 people. Relying on ErgoLAB platform, the experiment recorded the galvanic skin signal (EDA) and photoelectric volume pulse (PPG) of elderly people's conversational behaviors at different distances.ErgoLAB and SPSS software was used for data processing and analysis. Conclusion: Combined with the subjective questionnaire survey, it is concluded that the most comfortable hearing distance of the two groups of elderly people under the conversation behavior is 1.2 meters.
