    Abstract: Generally disclosed herein are transducers that can convert sound energy into electrical signals, such as to detect if a pressure wave includes a specific frequency. Methods of using the transducers and systems that include the transducers are disclosed herein as well. A transducer can include a first probe plate, a second probe plate, a ground plate situated between the first and second probe plates, a first electret film adjacent to a first side of the ground plate and situated between the first and second probe plates, and a second electret film adjacent to a second side of the ground plate and situated between the first and second probe plates, the second side opposite the first side.
