A Study on the Effect of Environment Sound on Human Thermal Sensation

In recent years, there have been several devastations caused by the global climate change. Global climate change is considered as relating to the global warming and is becoming a serious problem. Global warming is related to the increase of carbon dioxide. The increase of the carbon dioxide is caused by the energy consumption increase. In addition, air conditioning dominates the large ratio of the energy consumption. Furthermore, according to the huge earthquake happened on March 11, 2011 in Japan, the country's energy policy is facing a turning point, which is to establish less harmful and less energy based society than ever. For that reason, to decrease the energy consumption, how to reduce the energy consumption by the air-conditioning is an important issue. There have been several research relating to the topic. However, those researches did not study on the effect of the environment sound on the human thermal sensation. For that reason, the purpose of this research is to clarify the effect of environment sound on human thermal sensation. As the result of this study, the environment sounds, such as "Rain" "Stream" "Water Bamboo" showed the effect to lower the human thermal sensation.
