20130163779 | SOUND OUTPUT DEVICE - A sound output device for masking an operation sound generated by equipment, having: an operation determining unit that determines an operation mode to be executed by the equipment; and a sound output unit that outputs a masking sound on the basis of the operation mode determined by the operation determining unit, the masking sound changing at least in sound pressure level over time. | 06-27-2013 |
20130223870 | IMAGE FORMING APPARATUS - An image forming apparatus, having: a supply unit that forwards a sheet material; a rotor that feeds the sheet material; a memory unit that has stored therein a masking sound for noise; a derivation unit that derives a current position of the sheet material being fed; a determination unit that determines, on the basis of the current position derived by the derivation unit, whether or not the sheet material being fed has reached a second specified location at a predetermined distance upstream from the first specified location; a decision unit that decides output timing and/or output duration for the masking sound in the memory unit upon an affirmative determination by the determination unit; and a sound output unit that outputs the masking sound in the memory unit in accordance with the output timing and/or the output duration. | 08-29-2013 |
