Teledyne API requested that a solution be provided to reduce reverberation in the main lobby of their manufacturing facility. The lobby construction consisted of hard reflective surfaces, such as tile, glass and gypsum board.

Measurements were taken in the lobby showed excessive reverberation time with frequency bands exceeding 2 seconds (optimal 0.8). Based on the measurements the amount and type of absorption material was determined to bring the reverberation time down to acceptable levels. The results were detailed in a report and presented to the client.
