    The concept of soundscape aims to provide a more holistic understanding of the acoustic environment by taking several aspects into account, such as human perception, the acoustic environment and the context of the space. The soundscape concept is primarily concerned with the human experience and is considered more effective to access the acoustic quality of urban areas than traditional sound measurement. Soundscape analysis was used in this study to determine the relationship between various activities occurring in urban areas and their associated sound sources. This relationship can be used as design guidance for urban soundscape. The interaction was analyzed using the soundscape expectation approach, which is based on people’s memories of urban areas. The participants of this study were requested to compose an ideal acoustic environment according to their expectation for doing four activities: reading, relaxing, talking with friends, and playing with children. According to the data of the participants’ composition there is no significant difference in the overall sound levels between various activities. As a result, the appropriate acoustic environment cannot be determined solely based on the overall sound level. Individuals have varying expectations of sound sources when engaging in various activities

    Gamelan music differs from Western classical music in two fundamental ways - in the characteristics of the music itself and in the spaces that the music is played. There has been no previous research to determine the preference associated with both these aspects., and yet gamelan music are being played more and more in Western style concert halls and the impact of this on the subjective perception of the music is unknown. With this in mind, the objectives of the research were to determine: the preferred sound field design for Javanese gamelan performance hall, including: the preferred listening level, the preferred Initial Time Delay Gap, the preferred Subsequent Reverberation Time, and the preferred Interaural Crosscorrelation (lACC); and the preferred configurations of surface diffusion over the frequency range of interest for the Javanese gamelan music concert hall. Computer modelling and simulation method using ODEON and subjective preference testing using the output of the modelling will be used to obtain the end result.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    HOSPITAL SOUNDSCAPE: ACOUSTICS EVALUATION IN NEONATAL INTENSIVE CARE UNIT (NICU) ROOM OF A NATIONAL HOSPITAL IN JAKARTA, INDONESIA

    Acoustics comfort in a room is one of the most important building physics aspect that should be observed. in public spaces like hospital, especially in an intensive care unit such as NICU. Researches on the acoustic conditions of NICU in Indonesia are still limited. The acoustical study conducted in this research is using objective, subjective, and simulation methods based on soundscape concept with the concern on the nurse’s perception. This research was conducted at a national hospital in Jakarta. According to National Standardization Agency of Indonesia (SNI) and World Health Organization (WHO), the suitable sound pressure level (SPL) for noise in patient’s room is 35 dBA. From the study, it was found that the equivalent SPL value exceeded the standard. Soundscape in NICU can be improve with the addition of curtain on the incubator’s side, installation of glass partition, and ceiling absorber in the nurse station area. The result of simulation showed that the SPL in the room decreased with average value 8.9 dBA for sound source alarm ventilator and 8.2 dBA for sound source medical officer conversations. And the speech transmission index (STI) increased from “bad” to “good” range became “fair” to “excellent” range
