    摘要: According to one embodiment, a sound corrector includes a signal outputter, a response signal, a frequency specifier, a coefficient specifier, a filter, and an outputter. The signal outputter outputs a measurement signal to measure acoustical properties of an object to be measured. The response signal receiver receives a response signal from the object in response to the measurement signal. The frequency specifier specifies a resonant frequency at a resonance peak from the response signal. The coefficient specifier specifies a correction coefficient of a correction filter for reducing the resonant frequency based on the specified resonant frequency. The filter performs filtering on a signal to be output to the object using the correction filter with the correction coefficient. The outputter outputs the signal having undergone the filtering to the object.

The first housing is dividable into a first casing accommodating the DOC converter and a second casing accommodating the DPF, the two casings separably fastened by bolts. The inlet port of the first casing housing is bent inwardly in the width direction and detachably fastened to an exhaust pipe, the distal end of which opens outwardly in the width direction, through bolts. The second casing and housing are fixed to the frame through two brackets.
