Abstract: The purpose of this research is to find how to control temperature of water by using sound. This research suggests to apply sound to controlling water temperature based on the result of scientifically verifying that features of water sound vary depending on temperature. For analyzing features of water sound this study examined sound of water falling by sound analysis tool. Such different features of sound of water falling depending on temperature can be utilized in various fields temperature management for water purifier, sauna, swimming pool and hot spring as well as temperature control in fish farm or natural ecosystem. In terms of research method, water temperature is set on 100°C and reduced by every 10°C to scientifically analyze features of water falling sound. As a result, it was identified that sound is highly susceptible to temperature changes. Therefore, this research tries to make a proposal on application of water temperature control system by water to different fields.
