Holoplot Facilitates Audio Coverage at Africa's Largest Mosque

Hidden in the structure of Misr Masjid, recently built in Cairo (Egypt), the X1 Matrix Array system Holoplot provides optimal audio coverage in this 10.000 m2.

Recently built and considered one of the largest mosques in the world, Misr Masjid It has a space of 10.000 m2 to welcome 12.000 Faithful. In this sense, Deliver a clear and intelligible message to your congregation, without compromising on interior architectural design, Mainly marble, It has been a challenge to deploy the audio system.

With a totally concealed installation, the German multinational Holoplot It has managed to provide audio coverage throughout the mosque with its system X1 Matrix Array, Deployed only with Nine Speaker Array Positions, compared to other conventional sound systems that may require more than thirty positions to achieve sufficient and intelligibility within a space with those dimensions.

Each of these assemblies has been mounted at a height of up to 23 meters above the ground, hidden at a significant distance from the listener, Behind painted fabric or metal, That is invisible to the faithful.

Holoplot X1 Matrix Array handles an existing reverb time of 6 Seconds - caused by both marble interior, including pillars, as well as by the central dome of the mosque, to 60 meters high-, that allows energy to be diverted away from reflective surfaces and avoids deploying large amounts of acoustic treatment.

Emad El-Saghir, by Holoplot, explains that "this great mosque is an example of X1's technological capability. We introduced several completely new system concepts, that can't be achieved with any other technology. X1 arrays of matrices use advanced optimization algorithms to generate a uniform coverage in narrowly defined areas, with minimal spillage in quieter areas or reverberant surfaces".

As a result,, "Voice transmission and direct-to-reverberant ratio increased to record values. A solution based on steerable linear arrays would have required the implementation of many more arrays to achieve something comparable.", says Emad El-Saghir.

For its part, Emad Shenouda, Integrator Project Manager Audio Technology, He adds that "together with Holoplot we created a fully integrated system that satisfies all stakeholders. The project was full of challenges, Starting with the size of the mosque, the acoustics of the room, and, Of course, delivery times".

The X1 Matrix Array's ability to control sound not only vertically but also horizontally is another advantage pointed out by Shenouda, "as it achieves incredible intelligibility, impossible in a marble-clad space with a huge dome in the center. Holoplot's system exceeded our expectations, both in the sound quality and in the concealment of the equipment, that blends seamlessly with the interior".
