Sound was vibration that was audible to the ear.

Some lifeforms were highly sensitive to loud noise. These included the Sensorites, (TV: The Sensorites [+]Loading...["The Sensorites (TV story)"], PROSE: The Monsters from Earth [+]Loading...["The Monsters from Earth (short story)"]) the Voord, (PROSE: The Fishmen of Kandalinga [+]Loading...["The Fishmen of Kandalinga (short story)"]) the Ethereals in their cloud form (PROSE: The Cloud Exiles [+]Loading...["The Cloud Exiles (short story)"]) and the Verdants. (COMIC: Mission for Duh [+]Loading...["Mission for Duh (comic story)"])

The sound of static power pulses was associated with the Daleks. (COMIC: The Only Good Dalek [+]Loading...["The Only Good Dalek (comic story)"])

During the Dummy Massacre, (PROSE: Dummy Massacre [+]Loading...["Dummy Massacre (short story)"]) when the London Eye was activated by the Nestene Consciousness (TV: Rose [+]Loading...["Rose (TV story)"], PROSE: Operation Mannequin [+]Loading...["Operation Mannequin (short story)"]) at least one person on the Eye found themselves unable to see due to the brightness and unable to talk because of the noise. (PROSE: Dummy Massacre [+]Loading...["Dummy Massacre (short story)"])

A sonic screwdriver could project sound to lock or unlock doors. (TVThe Mutants [+]Loading...["The Mutants (TV story)"], Aliens of London [+]Loading...["Aliens of London (TV story)"])

Sound waves could reflect off of metal objects. Sonar systems used this property to determine the distance to an object. (PROSE: Doctor Who and the Sea-Devils [+]Loading...["Doctor Who and the Sea-Devils (novelisation)"])
