In this work, the Public Address and General Alarm (PAGA) system of a fire station building in Doha, Qatar was evaluated to ensure full coverage of speakers and maintain speech intelligibility in all premises of the building. For that, an indoor noise modelling study followed by mitigation measures was performed using SounPLAN 9.0. Two main parameters were in focus: total noise (LAeq) for the speakers' coverage and the Speech Transmission Index (STI), for the speech intelligibility. Generally, STI ratings over 0.45 are sufficient (reaching at least "fair" level) and LAeq with minimum 15 dB higher than the background noise satisfies the audibility. The complexity in this work appeared when the clarity of the sound could not be achieved in all areas without installing extra speakers, taking into account that the maximum allowed noise in terms of HSE Occupational Noise Level (85 dB(A)) was not to be exceeded on any of the premises. Several mitigation measures were examined, and the most applicable option was recommended taking into consideration workers' health, availability of speakers in the market, and cost efficiency. The solution for this case study with the most significant challenges is presented in this work.
