A study on low frequency noise of dehumidifier using acoustic characteristics

Abstract

The purpose of this research is to analyze sound characteristics of low frequency noise of dehumidifier and moreover, utilize it as a method to remove and reduce low frequency noise. Common noises made from dehumidifiers can be seen into two perspective; fan noise and low frequency noise. Especially, low frequency noise of dehumidifier tends to be louder than home electronic devices which have similar characteristics. Also, depending on the height of the machine, characteristics of noise may vary due to its structural feature. Therefore, this research studies those causes and research on fundamental parameters for identifying what makes low frequency noise and how to reduce it.
