Have you ever imaged theatre or auditorium filled with noises and raucous sounds? Just image it, we will hardly hear the movie dialogues in the movie or enjoy the performance in that huge crowd in that kind of environment. But thanks to the Physics, we have a great solution to eliminate or reduce the impact of the noise in such an environment. And that is Acoustical Engineering or Acoustical Solutions. It is an Architecture marvel which has been used since the Roman period for noise reduction and control.
