S0UND MIRR0RS
Also known as: Acoustic Mirrors, Concrete Dishes, or Listening Ears use their curved surface to concentrate sound waves by capturing the noise and focus it onto a microphone and our new software. The mirrors themselves are not of a new construction however the technology is now much more advanced. Although they are still in the phase of experiment we have much evidence that this particular technology is useful in tracing harmful sounds incoming from various directions.
