We investigated whether the rainfall intensity could be estimated with rainfall sound hitting on an umbrella. The rainfall intensity measured by Laser Precipitation Monitor (LPM) was regressed with sound pressures of various wave lengths.The rainfall intensity was evaluated with the accuracy of 0.28 mm/h in RMSE basis for rainfall events of 14mm/h maximum rainfall intensity irrerespective of umbrella materials and position of sound recorders as long as the regression equation were made to that umbrella-and-recorder system specifically.
