| 内容記述 | Abstract When we measure an underwater sound in summer at the coastal zone such as Seto Inland Sea, it is well observed that the peculiar crackling noise of “pachi pachi” as if in frying the “TEMPURA” was apparently intermingled with the ship noise less than 1 [kHz]. We call this TEMPURA noise. It is said that the tone pulse (duration time is about 1 [ms]) was occurred by accompanying with the spouting of the water by rapidly closing the one side scissors greatly developed of a snapping shrimp. In the field of underwater acoustics, TEMPURA noise has consistently been treated as a noise of an unnecessary one. Recently, there is a trend to utilize TEMPURA noise positively as a sound source of the circumference noise imaging sonar or to utilize the number of pulses as an index for marine environment and bottom material evaluation, etc. However, details of occurrence frequency or distribution of TEMPURA noise itself are unclear and an evaluation method of the number of pulses has not also been determined. In this study, a new evaluation method of the number of pulses (for example, pulses per unit time) is discussed. Because we devised a new technique to measure the number of pulses by using the image processing. In addition, by using the new technique, we report the TEMPURA noise measured at a pier of Japan Coast Guard Academy along with the marine environment data. |
