Field experiments were conducted at the Hiratsuka coast in Kanagawa prefecture from September 8^th to November 7^th, 2022, to estimate wave height using wave sound observed by a sound level meter and an IC recorder. The wave sound levels were observed at 55 m landside from the average shoreline position and 11.7 m above the average sea level. Every 10-minute observation (sound level meter, IC recorder, wind speed, wind direction, and air pressure data) was used in the analysis. Wave height can be estimated using the IC recorder as accurately as using the sound level meter (R² = 0.51), although a slight estimation delay occurs when the observed wave height is high, i.e., approaching a typhoon. However, the observations by the IC recorder included wind noise. Thus, sound pressure corrected based on the windscreen effect made it more accurate to estimate wave height by the IC recorder (R² = 0.53). Even if the way to reduce wind noise is very simple, the wave height was also sufficiently estimated (R² = 0.54).
