In this paper, we discuss the acoustic noise generated while driving an IH cooker with a power supply that includes high-frequency noise. This is because the acoustic noise generated from the IH cooker is of the order of kHz, which causes health issues amongst the users, e.g., headache, nausea, dizziness, and discomfort. In this study, we clarify the data that contribute to the formulation of the guidelines on acoustic noise specifically in 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, Japan. As a result, we clarified the conditions for generating acoustic noise that exceeds environmental standards.
