The goal of noise reduction in large auditoriums is to add sound absorption materials to reduce reverberation (echo) within the room.

Typically auditoriums and theaters have hard reflective walls and floors such as concrete block and there is a need for sound reduction. Adding sound control products such as acoustical wall panels will reduce ambient noise during events.

These sound absorption materials should be planned into the design of the auditorium, however they can be added as a retrofit application as the need for sound reduction within the facility is addressed.
