Abstract

A measurement device according to this embodiment includes a peak detection unit that detects positive and negative peaks included in a sound pickup signal, a sign determination unit that determines a positive or negative sign based on amplitudes at the negative and positive peaks detected by the peak detection unit, a peak group separation unit that separates a peak sequence composed of the peaks with the determined sign into a plurality of peak groups, a maximum amplitude detection unit that detects a maximum amplitude in each of the plurality of peak groups, a signal cutout unit that cuts out the sound pickup signal at cutout timing based on the maximum amplitude and generates a plurality of cutout signals, and a signal adding unit that adds the plurality of cutout signals.
