The brief
250,000
passengers a day
Problem
- Noise pollution into surrounding streets and adjacent platforms
- Cross-platform acoustic interference
- Restricted mounting positions on heritage fabric
- High intelligibility required in specific zones only
Solution
SC columns mounted horizontally, so each beam is shaped along the platform and held off the opposite one. Fewer cabinets than a conventional distributed system, with a more natural tone; built-in Dante and network daisy-chaining simplified installation and expansion, and transducer- and amplifier-level monitoring replaced assumption-based impedance line checks.
Outcome
- Noise pollution issues resolved
- Intelligibility increased
- Equipment count reduced
- Now installed in more than 100 stations
