The new Djamaâ el Djazaïr mosque was built around six kilometers east of Algiers' historic city centre. With a gross floor area of almost 400,000 m², it is the third largest mosque in the world after Mecca and Medina. The Great Mosque of Algiers has a prayer hall for up to 37,000 people and an approx. 265 meter high minaret. In addition to the prayer hall and minaret, the entire complex includes other facilities such as a museum with a research center for Islam, a cultural and congress center with a library, a Koran school, apartments and infrastructure buildings.

Particular attention was paid to the exceptionally large prayer hall with its 45-meter-high dome. The appropriate combination of room acoustics measures and innovative sound reinforcement solutions ensures a high level of speech intelligibility in this oversized room. Room and electro-acoustic simulations were used to determine the loudspeaker positions and optimize them from a design point of view. A modern sound reinforcement concept for the publicly accessible minaret ensures that the muezzin's call can still be heard at a distance of over 2 km. In addition to achieving excellent room acoustics in the hall of the culture and congress center, the sound insulation of the mobile partition walls was designed in such a way that two events can take place at the same time without disturbing each other.
