Due to the currently increased desire for improving the living environment of the residents in apartment buildings, some problems related to the noises from the indoor facilities & equipment have been raised and thus the requirements for improving the functions of such facilities & equipment and for reducing the noises from such ones are increasing. However, in case of the facilities & equipment, it is in the situation that such facilities & equipment are designed and established while the unique characteristics of the sound source and their effects on a unit house are not considered. Therefore, to predict the noisy situations in advance based on the noise characteristics of facilities & equipment and the types of rooms is a very important matter for reducing the noises from such facilities & equipment. In this study, the noise of the equipment, in order to understand the effect on the room, and using acoustic simulation. Flat-shaped, area, we tried to try to predict the noise reduction amount in the room due to the changes in the internal organs material. Kitchen hood noise through the field measurement of the apartment has to understand the impact on the living, We have applied the frequency another sound source characteristic value and terms and conditions to simulate. In kitchen hoods noise installed partition wall effects on the living room during the kitchen and living room, in the simulation after changing the sound absorbing material, to compare the results before and after change. We were compared with each other before and after partition-specific installation in the same plane. It was found that a considerable noise reduction effect from the plane after installing the partition wall. |
