Abstract: The problem of noise pollution and energy waste of a boiler room in a residential area of Dalian city is studied in this paper. The causes which induce excessive noise and energy waste are investigated by analyzing sound source and propagation path of the noise. Then a method, that can reduce both internal and external noises of the boiler room and can save energy, is proposed. A good effect in engineering application is obtained.

Key words: acoustics, boiler room, noise reduction, energy saving
