This paper discusses the high frequency acoustic noise generated by an IH cooking heater. Moreover, the generating mechanism of the high frequency acoustic noise is clarified by experimental study. Recently, influence of the electromagnetic wave on the human body is worried. The symptoms; user of home electronics appliances feels; are headache and nausea. There is a report that some users who are using IH cooking heater also feel these symptoms. We have discovered that the high frequency acoustic noise of high sound pressure level being generated by an IH cooking heater. The high frequency acoustic noise adversely affects our health. Then, it is necessary to examine the suppressing method of high frequency acoustic noise. The high frequency acoustic noise and the generating mechanism were clarified by the experiment.
