Final answer:

To quiet a room air conditioner vibration, you can modify the shape of the unit, install multiple physical pendulums, or use tuned-mass dampers to reduce the vibrations and create a quieter environment.

Explanation:

Quieting a room air conditioner vibration revolves around reducing the unit's oscillations. One way to achieve this is through modifying the shape of the air conditioning unit. This can be done by adjusting or repositioning certain external components that may be causing the vibrations.

Another method is by using multiple physical pendulums or counterweights. These are installed within the air conditioner and work by swinging in the opposite direction of the air conditioner's motion, thus offsetting vibrations and making the unit quieter.

You can also consider using tuned-mass dampers. These are devices designed to reduce, or 'damp,' the amplitude of mechanical vibrations. When fixed to the air conditioner, they absorb the energy causing the vibrations and convert it to heat, hence, reducing the vibration noise.
