환경문제로써 소음에 대한 민원이 증가하고 관심이 커지면서 소음에 의한 인체의 영향 연구의 필요성이 제기되고 있다. 이에 대한 국내의 연구가 미미하고 산업보건의 관점에서 다루어져 왔기 때문에 먼저 국외 기술조사를 바탕으로 연구의 동향을 파악한다. 환경요인으로써 인체 영향 소음을 정의하는 인자로 어노이언스(annoyance)가 많이 사용되고 있으며 소음레벨과 관련하여 다양한 정량화 모델이 제시되고 있다. 소음이 의한 인체의 손상에 대해서는 많은 가능성과 연관성이 제시되고 있지만 그 발생 메커니즘은 아직 구체적으로 밝혀지지는 않았다. 보고서들01 의하면 장기간의 소음 노출에 의해서 다양한 건강 손꼴이 나타나며 안락감의 파괴로부터 시작하여 만성적인 질환으로 발전한다고 추정한다.

Evaluation on the environmental noise is carried out by surveying subjective response of residents with physical measurement of noise during long period in field. Particularly field survey is used to make regulations from the analysis on how many people are annoyed for specific noise level, and laboratory test used to analyze the relationship between physical parameters of noise and subjective responses. In the laboratory controlling the variables is easy but the results could be biased because the condition in room would be different with field. Most of all noise exposure time is considered to be different with real situation, and this study aimed to evaluate the subjective response by exposure time of transportation noise, by applying three kinds of variable how much they give effects on the annoyance as the exposure time is operating condition, windows type and sound level. As a result there was somewhat difference between operating type and annoyance, which is caused by the sound characteristics operated in different condition. However the window type didn't give much effect to the annoyance as much as sound type. This means that the subjective response could give similar result by exposure time even for different window types. Most of all, the main factor affecting subjective response is considered to be the sound level and the exposure time.

There are many business in complex building, and recently noise claims have increased in those buildings. It is one of the most desirable methods reducing the noise level to establish the noise criteria considering the admittable noise level between the source and receiving room, which are to be derived from the subjective response in the real conditions. Because the degree of annoyance and loudness for the intruding noises in complex building could be changed with background noise level, it is suggested to be researched the relationship between the noise levels and subjective response. In this study, the subjective response for three different background levels in receiving business or rooms were investigated for the typical eight business noise source including aerobic music. The results can be summarized as follows. In conditions of low background noise level(40 dB(A)), there is a tendency of intentionally attention situation (listening) in a subjective test. The other hand in conditions of relatively high background noise level(50 dB(A)), there is a unconscious situation (heraing). As the degree of moderately heard or annoyed in SD rating scale means that the noise is easily recognized in neighboring shops, usually the limit of noise criteria were decided on this rating point, so it will be reasonable to be adopted the criteria rating scale as slight heard or annoyed degree (SD criteria 3).

Financial service chatbots are hindering user experience with conversational errors and machine-like responses. This study aims to examine the effect of self-disclosure and emotional expression of an anthropomorphic chatbot on user experience before conversation errors occur in financial services. In financial inquiries, scenarios were designed based on self-disclosure type (positive vs. negative) and emotional expression level(high confident vs. low confident), and online experiments were conducted. The result revealed that when anthropomorphic chatbot provided self-disclosure and emotional expression, the main effect has been shown on trust, annoyance, service recovery, and intention to continuous use. In addition, interaction effects were significant in trust and annoyance. In conclusion, this paper demonstrated that anthropomorphic chatbot's positive self-disclosure and confident emotional expression influenced trust and annoyance.

This study is a preliminary experiment to test on the effect of musical harmony on the suppression of the discomfort from tinnitus. The experiment was conducted on 25 adults with normal hearing. They listened to the three types (1. original music, 2. melody only, 3. harmony only) of Brandenburg concerto no. 3, G Major (J S Bach) and rated tinnitus annoyance scales. The results show that the tinnitus annoyance was significantly reduced when they listened to the tinnitus sound and any of the three types of the same musics compared to when listening to the tinnitus sound only (p < 0.019). Suppression of tinnitus was observed to be greater in the original music containing harmony and the harmony part only than in the music excluding the harmony part (the melody part only) (p < 0.012). The suppression effect was slightly better in the original music including the harmony part than in the harmony part only, but there was no statistical significance (p = 0.189). The experimental results suggest that the harmony in music plays an important role in suppressing tinnitus annoyance, compared to the melody. Validations with tinnitus patients are necessary to underpin the findings, which can enable us to embark further studies for making use of them for clinical applications.
