Abstract
A method to identify and classify a document (5) by weight or thickness based on the sound the document makes while moving through a document transport (30). Using an audio transducer (20), the sound of the document is captured and compared to previously saved and stored characteristics of various weighted documents and then classified when matched to a specific set of characteristics.
