Abstract: An arrangement of material layers designed and utilized as a filter to mechanical waves entering a sensor. To isolate the sensor, the filter can be designed to attenuate specified frequencies that could propagate from the environment and into the sensor. Provided there is a difference in the mechanical impedance between the environment and the sensor case, then a filter can be designed to amplify a specified range of frequencies, enhancing the coupling of the sensor to its environment. The filters work by altering the transmission and reflection of incident waves. Dissipative mechanisms are not required. Test data is included that demonstrates the effectiveness of layered isolation mounts developed to block inputs that would excite the resonance frequency an accelerometer's seismic mass.
