This study aimed to explore the types, levels and frequencies of musical activities shared by neurotypical siblings and their siblings with developmental disabilities, and their influences on perceived sibling relationships. An online survey comprising 92 items was conducted with neurotypical children aged 9 to 12 who have siblings with developmental disabilities under the age of 18. Descriptive statistics were used to analyze responses, and one-way ANOVA was conducted to examine differences in perceptions of sibling relationships and disability acceptance depending on the intensity and types of shared musical experiences. The results indicated that when neurotypical children shared musical experiences with their siblings with disabilities, their perceived closeness to their siblings and acceptance of the disability were significantly higher (p < .001). Furthermore, perceptions varied depending on the level of shared musical experiences. When interactions occurred during musical activities between siblings, neurotypical children perceived significantly higher levels of closeness towards their siblings, regardless of the specific balance or level of communication. Conversely, disability acceptance was significantly lower both when there was no interaction during the musical activities and when neurotypical children solely led the activities. This study provides significant insights into shared music experiences at home between siblings with disabilities and the influences of these experiences on perceived sibling relationships.

In this study noise source in a ward at four general hospitals in Seoul area has been investigated and analysed. The degree of reaction against noise by 171 randomly has also been examined. The results of the study have shown that the source of noise is the speakers of wired broadcasting or from visiting guests in two hospitals located in residential area. The patients at the two other hospitals located at commercial site have been suffered more from traffic noise. However, because of their separated living at hospital from their ordinary houselife, sixty one percent of the inpatients have wished a music sound of around 60 dB (A). After having considered the results of the investigation and wishes of the inpatients, following suggestions have been made: 1. Reduce the number of guests or their length of stay. 2. Wired broadcasting system should be substitued by wireless one, or if it's unavoidable, it should be used in office rooms only. 3. Since the stops and starts of vehicles induce much noise, Seoul City Government be requested to prepare an appropriate administrative measure for the vehicles around hospital area and it should prevent the establishment of new hospitals along high way site. 4. By using earphone, inpatients can choose a wireless channel according to each individual's taste. This through the masking effect, would cover up the noise source. 5. Rooms along the streets should be utilized as offices, otherwise double windows should be set up for inpatient's wards.
