A household-name company built a new regional call & data center in southeast Florida. As required by FERC, the Customer installed a large bank of emergency power gensets which were routinely run and tested.
Although the these natural gas powered generators were contained inside a CUP building, their exterior exhausts emitted noise levels in the 90 dBA range. The local noise ordinances required maximum noise levels 65dBA at the property line.
Their objectives were four-fold:
1. Install a combination of air compressor noise reduction products engineered for the extreme wind loads of SE Florida.
2. Install a combination of sound-absorptive products to meet the noise ordinance mandates.
3. Install a combination of compressor noise reduction products with the high acoustic performance necessary to mitigate the target frequencies emanating from their gensets.
4. Install a combination of sound-absorptive products that would be visually pleasing to the local community.
Under the guidance of their Acoustical Engineer, the Customer decided to use a combination of Sound Fighter® Systems’ (SFS) SonaGuard® sound-absorptive noise barrier system and RetroSorb® sound absorbing panels.
In summary, the maximum noise measured at the property line was 89 dBA. The post-treatment noise reduction is just over 33 dBA, resulting in a predicted noise level of 56 dBA.
In addition to the value-engineered, extreme wind-load acoustical barriers provided by Sound Fighter® Systems, their team was also instrumental in the use of helical steel piers instead of traditional concrete piers, due to very poor soil conditions at the site.
