Our acoustical work involves recommendations for the 300-seat Auditorium, Forum, Conference Room for 40 people, 12 Classrooms, 2 Seminar Rooms, Cadet honor/ sanction room, and Mechanical rooms. For the Forum, a large glass space that reflects sound in many directions, we constructed a 3D model using the actual room dimensions, surface materials, noise sources, and listener positions in order to assist in the selection of steerable speech reinforcement speakers. This speaker technology directs sound to specific locations, while avoiding extraneous projection of sound to the overall room volume.
The model was also used to help the project team get a better understanding of how different materials and geometries will impact the acoustical environment. Acoustical modeling also offers the ability to prepare “auralizations”, which are audible simulations of the sound in the room. The results can be played over headphones, which provide the most realistic sound, to actually listen to the space before it is built. Iterations with different finishes, speaker locations, etc. increased the information available to the project team for design directions.
