ASTANA, Kazakhstan — Turkish integration company Asimetrik installed RCF’s TT+ Touring and Theatre series speakers within the 60,000-square-meter, 10,000-capacity Astana Hz. Sultan Mosque, one of the largest mosques in central Asia. The 90-foot diameter, 140-foot tall main hall has one main and eight smaller cupolas.
All floors are covered with woven carpets, resulting in a fair amount of absorption on the higher end. But most surfaces except for the floors are covered with marble and tile. While beautiful to look at, the reverberant surfaces challenge intelligibility within the big space. The halls are extremely reverberant, especially on the lower end.
To deal with those issues, Asimetrik modeled the structure using EASE 4.3 and used an exhaustive design process.
The goal was to provide a way to keep intelligibility and sound pressure levels as high as possible, taking into consideration that, when you have 10,000 people within a reverberant room, even the simple act of breathing creates significant noise. The RCF TT+ Touring and Theatre series speakers helped minimize the reverberation issues, and the powerful amps within the compact cabinets helped ensure that the setup would work within the mosque’s 120,000 cubic meters of space.
To minimize the visual impact on the aesthetic design of the interior space, the gear was customized to visually blend in with the surrounding marble and tile wall surfaces.
