Acoustic methods of invasive species detection in agriculture shipments

Stevens Institute of Technology in cooperation with the DHS Science and Technology Directorate and the U.S. Customs and Border Protection has been investigating engineering solutions to augment the current inspection process at ports of entry in an effort to minimize the threat posed by invasive species. This paper presents the initial results of acoustic sensors application detection of rodents and small insects in grains with the goal of improving the accuracy and effectiveness of current manual inspection methods.
