Project Experience: Noise Model Study for Launch Vehicles

The Challenge

The John. A Volpe National Transportation Systems Center (Volpe Center) is supporting the Federal Aviation Administration (FAA) Office of the Associate Administrator Commercial Space Transportation (AST) to assess the appropriate model for monitoring noise levels for launch vehicles.

The Strategy

To assist the Volpe Center, HMMH has researched existing noise and sonic boom models and their applicability to the computation of environmental impacts for the commercial space industry.  The study catalogs and evaluates existing noise and sonic boom models, investigates the necessity of a new model, describes the process of creating a new model if required, and determines if the recommended existing or new model can be integrated into the FAA’s Integrated Noise Model (INM).  In April of 2009, HMMH submitted a final report on its findings to AST which will assist AST in updating the guidance provided to commercial space permit applicants.
