According to one embodiment, a monitoring apparatus includes an acquisition unit, an analysis unit, a calculation unit, a storage, a determination unit. The acquisition unit acquires an environmental sound. The analysis unit performs frequency analysis to extract characteristic frequency components. The calculation unit calculates first values of metrics. The storage stores contour data generated by second values of the metrics. The determination unit determines whether or not there is a first measurement point in which a first value and a second value match, if there is no first measurement point or the change is not less than the threshold value, determines that the machines is abnormal.

Monitoring apparatus and method

A sheet conveying apparatus includes a conveying mechanism and a control unit. The conveying mechanism is configured to pick up and convey a sheet every first time interval T and includes a sound source which produces a plurality of element sounds attendant on conveying the sheet. The control unit is configured to control the conveying mechanism so that the element sounds are caused at times determined based on a second time interval. The second time interval is acquired by dividing the first time interval T by a division number n which is an integer of two or more.
