Abstract

This paper introduces a study for the noise reduction of a range hood for household. Generally, range hoods have a built-in sirocco fan from which harsh noises are generated. Though the harsh noises have low noise level, these kinds of noises make most of the users nervous. For the purpose of noise reduction, in this study, a perforated plate system is installed in the fan housing of range hood. From the experimental results, it is confirmed that the noise level emitted from the range hood was decreased more than 10dB(A) in all 1/3 octave bands due to the effect of noise reduction by perforated plate systems.
