summary This paper describes research results into the identification of heavy construction equipment, i.e., off-road trucks and scrapers, using acoustical measurements. Characterization of the load status, i.e., loaded or empty, is also described. Field sound measurements were gathered using an ordinary videocassette recorder. The sound signal was processed using a Fourier Transformation algorithm. Features of the acoustical signature were measured, and differences between trucks and scrapers were noted. Probabilities were established to define the likelihood that a signal was produced by a particular type of equipment. Characteristics of the load status were also defined. The research demonstrates the feasibility of identifying equipment type and load status using a passive acoustic sensor.
