Abstract
Based on a peak level of a waveform in a predetermined period after the input of the waveform started and a value indicative of the degree of change in the waveform in the predetermined period, a judging device determines whether the waveform is caused by a strike. Thus, the peak level and a value indicative of the degree of change in the waveform are considered to determine whether the waveform is caused by a strike. A waveform with a small peak level caused by a weak strike is not erroneously detected as noise, while accurate detection of strikes can be obtained.
