In the pit, the walls are specially designed to provide the best possible acoustics, ensuring that the sound of the orchestra flows through the entire venue without overwhelming the performance on stage. Many orchestra pits are also designed to have reasonably low decibel levels, allowing musicians to work without fears of damaging their hearing. Typically, a small platform in the pit accommodates the conductor, so that he or she can be seen by all of the musicians, who may sit in chairs or on bleachers, depending on the design of the pit.
