Materials used in acoustic transducer membranes need very specific qualities that in any real system require many tradeoffs to be made. Graphene and graphene related materials are a newly discovered class of materials with some exceptional properties that has the potential to make significant contributions to the performance of many acoustical transduction systems. The properties of graphene relevant to transducer applications are discussed and two graphene based films, an aluminum coated Graphene Oxide film and an aluminum coated reduced Graphene Oxide film, are tested in a ribbon microphone application. Physical and acoustical measurements of the films indicate that with minor improvements, ribbon transducers could significantly benefit from graphene-based materials.
