Experimental Investigation of the Relationship Between Noise Level and Thermal Power Inside the Boiler Plant – Study Case

The acoustic comfort of a building or house is typically given little or no attention during project planning and design. This study is aimed at quantifying noise pollution from a building technical room. To attain the research specified result, simultaneous measurements were recorded for the gas flow and noise level in the boiler room. The noise levels were recorded for different operation statuses of the boilers (different thermal loads). It was observed that noise level depends on the thermal load: the increase of thermal load is directly proportional to the noise level inside the plant room). Further, the measured values of the noise level were compared with literature predicted values and the maximum limit values from the Romanian norm. These research findings are useful for mechanical design engineers and architects in order to assure the noise protection and fulfill the residents’ expectations.
