Sonic modulator

The Sonic modulator was a Human-built sonic device probably reverse-engineered and based on the Doctor's sonic screwdriver.

More bulky than the sonic screwdriver, it could cause physical harm by emitting sonic waves and cause pain. Toshiko Sato, an employee of the Lodmoor Research Facility, stole plans for the device (or perhaps plans of the actual sonic screwdriver) and by order of a mysterious woman named Milton, made a working device from the plan's in exchange for the life of her kidnapped mother. However, as Jack Harkness stated, the plans wouldn't have actually worked except that, with her technical genius, Tosh re-figured the design so that it would work. Before her capture by UNIT, Milton tested the sonic modulator on Tosh's mother. (TW: Fragments)


 * Other functions of the modulator, if any, remain unknown.#

Other Variants
During the episode "Enemy Of the Bane" Mrs Wormwood employed a smaller and far less crude variant of the device concealed within one of her rings. the device bore the same name and was effective as a powerful weapon against both bane and human alike. However the power life was short and ran down quickly. In the episode "The Lost Boy" Nathan Goss employed a crude manually powered sonic modulator device which could knock a human unconciouss and earmuffs had to be worn as protection against the high frequency soundwaves. Whether this was built specially by him from Earth technology or was an actual piece of Slitheen technology is as yet unknown.
