Case Study: Revolutionizing Sound at Sydney Central Railway Station

Background
Sydney Central, a heritage-listed railway station and one of Australia's most significant transport interchanges, serves over 250,000 commuters daily. Clear, intelligible travel announcements are critical to ensuring passenger safety and satisfaction in such a high-traffic environment. To meet this demand, EDC Acoustics was tasked with delivering a state-of-the-art audio solution capable of minimizing environmental noise spill and cross-platform interference while maintaining exceptional sound quality.

Challenges

• Noise Pollution: Reducing sound spill and preventing cross-platform acoustical interference.
• Mounting Positions: The need for compact, discreet speaker placement in a historically significant structure.
• High Intelligibility: Ensuring announcements are clear and intelligible in a busy, noisy environment.

Solutions
EDC Acoustics implemented a system featuring SC30, SC60, and SC90 speakers to address these challenges. Key solutions included:

• Horizontal Mounting: Enabled precise sound placement, reducing noise spill and cross-platform interference.
• Enhanced Audio Quality: Provided a natural tone superior to conventional distributed speaker systems.
• Fewer Speakers Required: Reduced installation complexity and costs by using fewer, more effective speakers.
• Advanced Monitoring and Connectivity: Integrated Dante and network daisy-chaining simplified installation and expansion. Remote monitoring capabilities ensured reliability by detecting transducer or amplifier failures with pinpoint accuracy.

Outcome

• Noise Pollution Resolved: Significant reduction in environmental noise spill and cross-platform interference.
• Increased Intelligibility: Clear, precise announcements throughout the station.
• Cost Efficiency: Fewer speakers reduced installation disruption and long-term maintenance costs.
• Scalable Solution: The system has been successfully installed in over 100 stations, setting a benchmark for transport audio systems.

Equipment

• SC30
• SC60
• SC90

Key Features

• Accurate Coverage: Beam-shaping technology ensures even sound dispersion, delivering announcements with absolute clarity to every corner of the station.
• High Intelligibility: In life-critical situations, EDC technology guarantees 100% audio coverage for essential announcements.
• Noise Pollution Reduction: Sound is delivered precisely where needed, minimizing spill to unintended areas.
• Versatility: Built for both internal and external use, the award-winning S-Series speakers perform reliably in any environment.
