The 'Floating Clouds' are not the only element that helps to provide the characteristic sound quality to the Aula Magna.
Within the auditorium most of the elements and materials are designed in favor of acoustics and durability.
The seats exemplify this.
They are made from the wool of either Chilean or Australian sheep (sources contradict) and were woven in England with a stitched furrow, have leather arms, and have seat cushions that automatically retract and are perforated on the bottom.
This design gives the seats the quality of counteracting sound variations, both when empty and fully occupied.

Another element is that all the doors in the room are acoustically designed and double-layered (internal and external); on the parterre level the internal doors are made of perforated metal and filled with an insulator, while the external ones are made of wood, creating a vacuum between them that prevents both the exit of sound from the hall and excludes external noise.
On the balcony level, the doors function in the same way, though both the internal and external doors are made of wood.
There is also a folded wooden canopy positioned eight meters above the stage to further soften sound.

The original design of the hall included aisle carpets made of cashmere wool, which also helped the acoustics.
However, during renovations in the 1990s, the carpets were replaced with ones made from synthetic material.
