A beam damper for damping acoustic noise generated by an actuator of a disc drive. The first step of the process is the step of providing a circuit design in the form of a hardware definition language. First and second compressible membranes are configured to electrically connect corresponding first and second conductive plates to a surgical field when subjected to a compression bias. Additionally, an additional processing step is applied to the data to account for the non-linear nature of cross talk filtering.
