In order to measure biomagnetic fields such as magnetoencephalogram (MEG), magnetically shielded room (MSR) with multi layers of μ-metal is usually used to reduce environmental magnetic field noise. However, such heavy-shielded room is not suitable for magnetocardiogram (MCG) measurement system from the requirements of low cost, lightweight, and small space.<br> We have studied an environmental noise reduction scheme for MCG application. Our noise reduction system consists of a prefabricated MSR of single μ-metal layer, a noise detection coil, and compensation coils. The following results were obtained for the suppression of environmental noise: 30 dB at 0.5-10 Hz and 30-50 dB at 10-100 Hz.<br> In this paper, the compensation set-ups are described and experimental results are presented and discussed.
