Desire is to reduce cabin noise resulting from fuselage vibration generated by engine rotor unbalance disturbances; simplified analytical model is used in combination with experimental impedance data to investigate effectiveness of several schemes applied to engine/airframe interface; airframe vibration absorbers are found to be most effective; qualitative correlation is achieved with results of installation of absorbers on Douglas DC-9 aircraft; more comprehensive analytical model is generated to account for three-dimensional effects; data acquisition for this model is discussed.
