| Outline of Final Research Achievements |
The relationship between sound of rainfall and conventional many rainfall information was analyzed. 1) Observation: terminal velocity of raindrop, wind, rainfall intensity, drop size distribution, and sound information were measured. Additionally, the sensors were set in a driving car, and the effects of noise sound was observed. 2) Understanding of sound of rainfall and conventional many rainfall information: the mean diameter of raindrops are strongly related with the sound intensity of rainfall. This kind of information can be utilized for disaster prevention. The results of this study can imagine the creation on science of rainfall sound.
