Amplitude
The quantity or amount of energy produced by a vibrating component (G force). An extreme vibration
has a high amplitude. A mild vibration has a low amplitude.
Backlash
Gear teeth clearance.
Boom
Low frequency or low pitched noise often accompanied by a vibration. Also refer to Drumming.
Bound Up

Brakes Applied
When the service brakes are applied with enough force to hold the vehicle against movement with the
transmission in gear.
Buffet/Buffeting
Strong noise fluctuations (less than 1000 Hz) caused by gusting winds. An example would be wind
gusts against the side glass.

sound. Also describes a high frequency (200-800 Hz) vibration. Vibration feels similar to an electric
