Despite this, it can be solved by raising the stage, elevating it above the seats and allowing the sound source to project directly to all the occupants.
Figure 4.1.3: Elevated source arrangement reduces SIL loss. The seats within the Connexion@Nexus Auditorium are in the most effective configuration that defines the relationship between the speaker on stage and the audience. As such if they are raked (raised), they can increase the chance of allowing the occupants in the furthest-most seats to hear clearly. This is possible due to the effectiveness of the sound waves reaching the ears of the occupants when uninterrupted by any objects blocking or absorbing it.

Arrangement of Seats The seats within the auditorium are arranged in a fan shaped configuration, to ensure a maximum number of seats are fitted, and to obtain an optimum view of the stage area from every seat. Most importantly, it helps achieve the most effective acoustic quality because sound waves travel in a spherical order. In addition to this theory, it is also important to note the angle of which the seating arrangements are fanned-out. It is tested that by including a 140-degree sound projection angle from the centre of the sound source on the stage. Should all seats fall within the angle of the sound projection area, the seating arrangement is well configured and deemed effective.
