PURPOSE: A noise reduction device is provided to decrease deterioration of a stereo sound by reducing the degree of stereo signal separation in a high frequency wave band when receiving an FM stereo broadcast. CONSTITUTION: A noise reduction device according to the present invention comprises a matrix circuit (100) for outputting an L signal and an R signal upon receipt of the same, a first level adjusting circuit (200) for adjusting the level of the L signal outputted from the matrix circuit (100), a second level adjusting circuit (300) for adjusting the level of the R signal outputted from the matrix circuit (100); an electronic volume section (500) for inputting the level-adjusted L and R signals through each capacitor (400) used for combination. |
