Comet CAPE™ is a graphical user interface application that guides and expedites the process of acoustic performance evaluation and optimization of noise control treatments in passenger vehicles.  CAPE is used to predict sound pressure levels in the passenger compartment for various noise control treatment (NCT) configurations.  The user can quickly and easily predict the effects of NCT changes such as changes to NCT material properties, thickness of NCT layers, order of NCT layers, etc.  CAPE allows the user to start with an existing template SEA model that incorporates SEA modeling best practices and expertise.  The user selects from a library of template models.  CAPE then guides the user through the process of modifying the template model such that it represents a specific design candidate.  CAPE also contains a database of NCT material property data.
