Abstract: This paper discusses high frequency acoustic noise generated by an
IH cooker. Mechanism of the high frequency acoustic noise generation is
clarified by experimental study. Recently, influence of the electromagnetic
wave on the human body is worried. They symptoms some users of home electronic
appliances feel are headache and nausea. There is a report that other users who
are using IH cooking heater also feel these symptoms. We have discovered that
the high frequency acoustic noise, which is generated from an IH cooker,
indicates strong-level sound pressure. High frequency strong acoustic noise
must not be ignored, because its danger on our health is reported
scientifically and medical standpoints. Then, it becomes necessary to examine
the suppressing method of high frequency acoustic noise. In this paper,
generating mechanism of the high frequency (20 kHz ∼) acoustic noise is
clarified by the experiments.
Keywords: IH cooker, high frequency acoustic noise, vibration
