Abstract
The work machine includes a path leading into a housing from an opening. The path is provided to control an airflow generated by motion of a machine. The work machine includes a microphone. The microphone is configured to collect sound in the housing, including operating noise generated in the housing by the motion of the machine. The work machine further includes a structure that defines a receiving space for the microphone along the path through which the operating noise propagates outside the housing. The structure includes an open structure that connects the receiving space with the path and faces downstream in the path. The structure surrounds the receiving space upstream of the open structure in the path.
