Acoustic quieting

Acoustic quieting is the process of making machinery quieter by damping vibrations to prevent them from reaching an observer.

One of the major reasons for the development of acoustic quieting techniques was for making submarines difficult to detect by sonar.

This military goal of the mid- and late-twentieth century allowed the technology to be adapted to many industries and products, such as computers (e.g. hard drive technology), automobiles (e.g. motor mounts), and even sporting goods (e.g. golf clubs[1]).

Each aspect of acoustics can be taken alone or in concert so that the result is that the reception of noise by the observer is minimized.

Acoustic quieting might consider: By analyzing the entire sequence of events, from the source to the observer, an acoustic engineer can provide many ways to quieten the machine.
