Silence in the Dark is a melodious, resonating song. All objects vibrate at a particular frequency. When she projects and hits an object with the same frequency, the vibration begins to resonate throughout the object, strengthening until the object shatters like glass. The target can literally be anything, such as an opponent's vital spot such as their arm ligaments to prevent them from moving. By matching the hearts resonance frequency, user could even cause a heart attack.
