    A Sound Solution in Correctional Facilities (2017)
http://www.corrections.com/news/article/45670-a-sound-solution-in-correctional-...
  
            "Currently, most prisons deploy some type of surveillance and access control system. One technology that many detention centers have not fully tapped into is audio. For wardens looking to enhance a current security solution at a cost-effective price, deploying audio monitoring through microphones and sound sensors is the answer."
