At Lingshui Xin Village Pier, three functionally distinct floating bridges operate around the clock. Owned by different tourism companies, these floating bridges serve as vital gateways for receiving tourists and showcasing services. However, during long-term promotional activities where each bridge broadcasts advertisements, the overlapping sound interference not only compromises the clarity of information for visitors but also creates a chaotic acoustic environment across the pier. This issue remains a persistent challenge for both the port management company and the tourism enterprises.

To fundamentally address this issue, the port management company has introduced Doctor of Directional Listening's highly directional speakers, bringing an acoustic revolution to Xin Village Pier. This innovative product leverages precise sound field control capabilities to concentrate sound energy within specific zones—as clearly illustrated in the sound field diagram below, each floating bridge's advertisements are confined to its own service area without spillover into adjacent zones, effectively preventing audio interference between different bridges.

Today at Lingshui Xin Village Pier, visitors can clearly hear the tourism service introductions from their own floating bridge, enabling more efficient communication of promotional information by various tourism companies. The port management company has successfully implemented orderly control over the pier's acoustic environment, enhancing overall operational quality. Qingwen Technology's directional speakers provide an innovative technical solution to scenario-specific acoustic challenges, injecting new vitality into the optimization of public sound environments.
