generally reduce low frequency vibration significantly, but it is very effective at higher frequencies (above c Hz).
If pumps, motors etc are bolted to steel plates, frames or tanks, then these behave as loudspeakers. The isolation prevents the transmission of the higher frequency vibration components, reducing the noise. David Thompson, in Railway Noise and Vibration, Wave-impeding blocks (‘WIB's) As the highest components of vibration are controlled by the softer and relatively shallow upper layer of soil that is commonly found, there is some potential in the idea.
Increasing damping or stiffness can both reduce resonant vibration and the resulting noise by preventing the vibration from travelling through the structure. Rubber mounts with damping properties are often used in engine compartments, enclosures, cab walls, and floor and ceiling systems; additionally, they are beneficial for use in appliances.
Within a vehicle many components contribute to the vibration levels experienced and to the overall emitted noise between 60 dB(A) and 70 dB(A) of a vehicle ().Having different dominant noise and vibration sources of the same order (e.g., within 4 dB(A)), the treatment of only one source will not affect the overall vibration levels and radiated noise.

Noise and Vibration Reduction Technology in New Generation Hybrid Vehicle Development The new gasoline hybrid car, “the Prius”, has achieved both two-liter class power performance and world top-class gas mileage with the new Toyota Hybrid System “THS II”.
VEHICLE GEARBOXNOISE AND VIBRATION. Welcome to our own blog, We have created this blog to post information, tips, tutorials videos to all the engineers worldwide, We hope you enjoy our blog as much as we enjoy offering them to you. This paper describes NV reduction technology for problems peculiar to the hybrid vehicle such as engine start/stop vibration, drone noise and vibration at low engine speed and motor/generator noise and vibration.
It also compares the overall NV performance of the hybrid vehicle with conventional gasoline engine vehicles.This book brings together coverage of the theory of railway noise and vibration with practical applications of noise control technology at source to solve noise and vibration problems from railways.
Each source of noise and vibration is described in a systematic way: rolling noise, curve squeal, bridge noise, aerodynamic noise, ground vibration.Other techniques to reduce product noise include vibration isolation, application of acoustic absorbent and acoustic enclosures.
Acoustical engineering can go beyond noise control to look at what is the best sound for a product,  for instance, manipulating the sound of door closures on automobiles.
