<p>An embodiment of the present invention provides an apparatus and a method for controlling a noise of financial equipment, which are suitable for outputting an output value stabilized by controlling noises which are differently produced from financial equipment. The apparatus comprises: a first magnetic resistance sensor provided in a region through which media passes and configured to perform at least one between an operation of measuring a magnetic component value of the media and an operation of measuring a value when there is no magnetic component; a second magnetic resistance sensor provided in a region through which media does not pass and configured to measure a noise of the financial equipment; and a frequency filtering means connected to the second magnetic resistance sensor to adjust a resistance value so as to control the noise of the financial equipment.</p> |
