Metalwork room with a 3.8 second reverberation (echo) that's noisy by any standards Sound Absorption Panels were fixed to available wall space and suspended from stay wires, which were chemically achored to adjacent walls.Resulting in a reverb reduction from 3.8 to under 1 second.
We had the good fortune to meet the Metalwork teacher prior to the Installation, giving us a real sense of how Difficult it was for him to teach in this classroom. This class could NOT be used for Theory, the teacher would have to find a vacant class for this purpose. Hearing Fire Alarms was also a problem.
