The Sonic Booster fills most of the space in the Master Control Console's pedestal and is connected to the base of the time rotor's pedestal with high amperage cables. The Booster is controlled by the Tremulator Switches. The two Temulator Switches control the transmission of sonic vibrations to the area outside the TARDIS. They can be used to cancel dangerous vibrations, such as local earthquakes, tidal waves, and hurricanes. In an emergency the Sonic Booster can be modified into a omnidirectional sonic weapon.
The sonic booster might also be used to aid in a Gallifreyan's regeneration in a process similar to Lazarus's Genetic Manipulation Device, which used resonances from hypersonic waves to destabilize the user's cells for regeneration.
