Resonator caps have been used for several decades to refine the high frequency response of microphones. These caps create a resonant cavity in front of the diaphragm to extend and shape the high frequency response. This work studies the experimental use of a variable-geometry resonator cap. This cap allows the user to select a desired high frequency response in real time, using only acoustic methods. Data collected in an anechoic chamber shows clear changes to microphone on-axis high frequency response with just small changes to the geometry of the resonator cap. This concept could be applied to allow user-adjustable high frequency response in a microphone, or it could be used as a lab tool to help acousticians quickly find the desired resonator dimensions.
