Perfecting shopping mall PA systems
The Gate is a mixed-use scheme in the business district of Doha, the capital city of Qatar. It comprises two towers of residential and commercial office space above a luxury shopping mall. The 150,000-m2 development includes underground carparking, a gym and a health centre. Cole Jarman, an RSK company, completed a full acoustic design brief covering traffic noise intrusion, sound insulation and mechanical services noise affecting the offices and retail areas.
Acoustic modelling of the shopping mall was undertaken to determine the intelligibility of the PA system. Based on the information gathered, recommendations were then made on the proposed internal finish and layout of the PA system to ensure suitable ambient noise conditions, suitable reverberation times and acceptable intelligibility.
