Biamp Solves Sound Problems at Georgia Southern University Stadium

Community LVH-900 beamforming speakers have been installed Biamp to override inherited settings, thanks to its ability to electronically direct sound and control coverage patterns without moving the physical array.

In preparation for a new American football season, the Georgia Southern University needed to solve a critical problem in their stadium: the existing sound system could not overcome the roar of the crowd. Announcements and live broadcast audio were often lost in the noise, and when more was demanded of the old system, was distorted a lot.

The Biamp team, led by principal engineer Charlie Hughes, stepped in with a smarter, more adaptable solution. They were selected altavoces beamforming Community LVH-900 to override inherited settings, for its ability to electronically direct sound and control coverage patterns without moving the physical array.

Thanks to VenuePolar and FIRmaker software, inside Ease Focus 3, No physical changes were necessary to the Biamp Community LVH-900 beamforming speakers., brand that distributes AVIT Vision, to improve audio in the stadium.

When Hughes and Biamp's team arrived on the scene, the speaker arrays were already installed and wired, so there was no possibility of physically reorienting them. Initial testing revealed uneven coverage and a significant reflection issue from the press box and sports hall. Given the importance of time and the impossibility of making changes to the hardware, Hughes turned to software-based optimization.

“The ability to electronically modify the vertical coverage pattern to overcome unforeseen challenges has saved us tens of thousands of dollars and weeks of time”, explains Charlie Hughes, chief engineer.

Via VenuePolar and FIRmaker within Ease Focus 3, The team adjusted the beamforming filters to redirect the output away from reflective surfaces and redistribute the sound pressure level (SPL) throughout the stadium.

The reflection of the pavilion, which initially caused significant intelligibility problems, was reduced by up to 9 dB. When this adjustment negatively affected the SPL in the most remote areas, The team reviewed the filters again and reached a compromise that reduced the reflection levels in 6 dB while maintaining powerful coverage with only a loss of 3-4 dB SPL in the farthest seats.

The final settings of on-site equalization allowed the sound to be further refined. Despite initial concerns about the balance between bass and mids, a few minor tweaks resulted in a rich and intelligible audio experience. No physical changes were necessary., Not even the subsequent visit of Hurricane Helen could move the fixed matrices.

According to Hughes, The project demonstrated the power and flexibility of the LVH-900 series. “The ability to electronically modify the pattern of vertical coverage to overcome unforeseen challenges saved us tens of thousands of dollars and weeks of time. All, from the integrator to the university staff, “They were delighted with the result”.
