Public address systems in building complexes have to inform members of the public about escape directions in case of emergency. Such public buildings include airports, railway stations, shopping centers and concert halls. However, if such announcements are misunderstood due to poor system quality, tragic consequences may result. Therefore, it is essential to design, install and properly verify the speech intelligibility of such sound reinforcement systems. In addition, common public announcement systems may have legal or contractual requirements regarding the level of speech intelligibility, such as in medical, industrial or commercial environments.
