At the fishing port pier in Lingshui New Village, Hainan, a wonderful scene is unfolding: fishermen can clearly hear the dispatch and command broadcast, while the residential area and sea just a few steps away remain peaceful as usual. Behind this is an innovative acoustic technology - the transformation brought about by the directional listening PhD outdoor strong directional sound system.

Unlike the traditional "indiscriminate diffusion" transmission method of audio, the core advantage of directional listening for outdoor speakers is that it can firmly lock sound waves in a specific area like a "sound searchlight". At the Xincun Fishing Port Terminal, staff only need to operate equipment to accurately transmit safety regulations, tidal information, fishing trade tips, and other content to target areas such as tourist boarding areas, trading areas, and fishing boat docking areas. Fishermen and tourists in these areas can hear clearly, while the passages and surrounding residential areas just a few steps away are almost undisturbed, truly achieving "those who should hear can hear clearly, and those who should not be disturbed are not disturbed".

Technical advantages:

1. Accurate sound transmission and peaceful environment: Through directional sound technology, the broadcast sound is concentrated and transmitted only in the required areas, achieving zoning control of sound and minimizing its impact on the surrounding environment.

2. Strong anti-interference ability and high message clarity: The fishing port environment is complex, and traditional broadcasting is susceptible to interference from wind, rain, and machine sounds. Directional sound technology can effectively penetrate environmental noise, making information transmission clearer.

3. Strong installation flexibility and adaptability to various environments: According to the characteristics of the fishing dock, various installation methods such as wall mounted, suspended ceiling, or bracket mounted can be ***ed to meet the needs of the complex environment of the fishing port.

4. Energy saving and environmentally friendly, with low maintenance costs: Due to the fact that sound only propagates to specific areas, energy loss is small, making it more energy-efficient. The outdoor protection design of the system also reduces maintenance requirements.

The application of directional listening Doctor outdoor strong directional sound system in Lingshui New Village Fishing Port Terminal is not only a practice of technological innovation, but also a reflection of humanized design. It reduces noise pollution, improves communication efficiency, makes dock work more orderly, and makes the surrounding environment more peaceful.
