The vibration of the crankshaft is transferred to the interior sound as a structure-borne sound. Therefore, the rumbling sound is caused by the resonances of the structures on the way of transfer path from the engine to car body.
The correct solution to mitigate all structure-borne sound requires a minimum buildup of 2.5 inches.
Part of gear mesh excitation vibration is transmitted through the air into the helicopter cabin as sound, and the other part is transmitted through the support structure between the main gearbox and the fuselage, thereby entering into the airframe and finally radiating structure-borne sound into the cabin [4].
It features a 2 mm vulcanized surface fusion bonded to a 5 mm recycled rubber backing to reduce structure-borne sound. Galaxy rx is available in 12 earthtone colors.
SEA was also applied to predict structure-borne sound. The air handler in the prior section (Figure 5) was again considered.
The structure-borne sound is still a challenging problem in engineering especially in buildings where machineries such as fans, compressors, hydraulic equipment, electrical motors, heating pumps, washing machines, and air conditioning system can produce a considerable amount of vibration [1].
Without some kind of cushion on concrete surfaces, the sounds of pounding feet and moving furniture can travel freely between floors, resulting in unacceptably high levels of thumping, thudding and pitter-patter of what acoustical engineers call structure-borne sound.

There are two types of sound that may have leaked from the sender's room: structure-borne sound (caused, for example, by senders stamping their feet on the floor or striking their hands against the arms of the chair) and airborne sound (caused, for example, by senders giving off vocal cues of delight or encouragement).
In order to enhance the safety of Russian nuclear power plants, the Energy Production Department (KWU) at Siemens AG, Germany, has supplied ten complete structure-borne sound, vibration and acoustic leakage monitoring systems.
