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 perspectives; 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
This research looks into parameters for reducing errors of judgment intoxication by comparing speech characteristics before and after drinking using speech analysis. In this study a drinking is tested to speech signal under overloading condition, there are many of some errors in unstable conditions. Therefore, it should be determined by using judgment algorithm that is not affected by overloading. So we have searched valid frames using energy of speech before and after drinking were extracted and drinking possibility was identified by using deviation from the distance of frames. In terms of speech frame energy its value changes greatly in overloaded but energy ratio largely stays the same in normal. Therefore, after applying overloaded signals to proposed method, we get this similar result with a normal input signal was obtained
