The design of interior acoustics, how your room sounds, is often thought of as equal parts science, art and real world practical experience.  Think about some of the most revered recording studios, often designed not by acousticians, but by people with a feeling for what was needed, and maybe a little luck.   Then, consider examples of massive concert hall projects with the best math behind the acoustics, turning out poorly.  Successful acoustical design comes from knowing how and when to blend each of these skills.  A great sounding room is the foundation of a great mix, recording, production or event.
