A Study on the Evaluation and Characteristics of Architectural Facility-equipment Noise in Building

On account of the technological development, intelligent building is on increasing where the artificial regulation on indoor environment is possible, thence the concern about those facilities such as water-supply facility, water-heater and drainage facility has becomes higher. However, due to diversification and complicated system of the facility-equipments, the noise gen- erating from such facility equipment is gradually becoming a problem, and since especially equip- ment noises arising at the machine room frequently infringe into the resident's pleasant living envi- ronment with the complex types of an air-borne sound and a structure-borne sound, it is becoming the civil complaint. On such viewpoint, this Study ever observed the characteristics of noise gen- erating from various facility-equipments in the building, and intended to evaluate the facility-noises by use of the valuation index such as PSIL, N, NC, NR. As result of, the facilities noise which happens in the machine room makes normal conversation very difficult due to high sound pressure level. Based on such data, this study is willing to present it as an essential material for establish- ment an efficient measure against the facility-noises arising at machine room hereafter.
