In this paper, we discuss the acoustic noise generated when driving an IH cooker with a power supply that including high-frequency noise. Because, the acoustic noise generated from the IH cooker is on the order of kHz, which causes health damage to users. Examples include headache, nausea, dizziness, and discomfort. In this study, we clarify the data that contributes to the formulation of guidelines on acoustic noise specific to IH cookers. We conducted an acoustic noise measurement focusing on the amplitude and frequency components of the noise contained in the power supply. The measurement results were compared with the environmental standards announced by the Ministry of the Environment. As a result, we have clarified the conditions for generating acoustic noise that exceeds environmental standards.
