Directional Sound Wave Bird Repellent Devices Upgrade Airport Bird Control Safety

2026-03-27

As winter gives way to spring, migratory birds that have flown south for the winter begin their journey back north, and bird control at airports enters a crucial stage for the year. Bird control at airports is not only a core defense line for ensuring the safety of take-offs and landings but also an important issue for maintaining ecological harmony. How to strike a balance between safeguarding aviation safety and protecting birds has become a key issue for airports.


At Kunming Changshui International Airport, the bird control team remains on the front line, with the "main battlefield" being the area around the taxiway. To strengthen the air safety defense line, the airport has established a comprehensive and round-the-clock prevention and control system based on bird control needs. Through a series of professional equipment and management measures, it has woven a tight net to prevent bird intrusions, ensuring the safety of every take-off and landing.

In response to the complex scenarios and core demands of bird control at airports, Guangxi Hai Zhuo Technology has precisely targeted its efforts, customizing a professional airport bird repellent solution to provide efficient and reliable technological support for airport bird control. Among them, the HIZ-SP-NDX directional sound wave bird repellent device, as the core equipment of the solution, has become a "hardcore weapon" for airport bird control with its professional design and advanced technology.


The bird repellent device consists of four core modules: a strong sound wave generation system, a fixed device, an intelligent control system, and a power supply system. These modules work together to achieve a comprehensive upgrade in bird repellent functions. The intelligent control system is its "smart brain", composed of a control system module, a power amplifier module, a bird repellent signal playback system, and an operation platform. It is equipped with a wireless control module, breaking the operational limitations of traditional bird repellent devices.


Relying on the wireless control module, the HIZ-SP-NDX directional sound wave bird repellent device supports remote control of designated equipment operation. Maintenance personnel can flexibly complete operations such as volume adjustment, play/pause, and command termination on the control terminal without having to be in close proximity to the device, significantly enhancing the convenience and safety of bird repellent operations. At the same time, a standardized signal playback system and precise power control ensure that the bird repellent sound waves are transmitted directionally and precisely cover the target area, achieving efficient bird repellent results while avoiding interference with the surrounding environment and non-target birds, fully balancing aviation safety and ecological protection.


Let's take a look at the product advantages of the sound wave bird repellent device:

1. Dual Repellent, Efficient and Safe

It adopts high-intensity sound wave technology, with the dual functions of dispersing both people and birds, effectively addressing complex scene requirements and ensuring regional safety and order.

2. Long-Distance Broadcasting, Sound Travels Miles

(1) It has the ability to broadcast over long distances, with clear and loud sound and strong penetration, with an effective range of 2000-5000 meters;

(2) It is particularly suitable for vast areas such as the wild, sea, beaches, mountains, large industrial and mining areas, and hydropower stations, meeting the needs of remote warning, alerting, or broadcasting.

3. Precise Coverage, Strong Deterrence

(1) The warning distance reaches 500 meters, effectively dispersing birds and creating a safety barrier;

(2) The sound wave transmission range is up to 2000-5000 meters, ensuring wide coverage and no blind spots in protection.

4. Intelligent Sound Source, Scene Adaptation

It is equipped with multiple pre-set sound sources (sirens, alarms, professional bird repellent sounds, etc.), which can be switched with one button, flexibly adapting to different repellent scenarios and improving efficiency and targeting.

5. Military-Grade Quality, Durable and Long-Lasting

(1) It features a high-strength aluminum alloy shell, resistant to corrosion and impact, with easy installation and maintenance;

(2) It is designed to military standards, supporting long-term operation in a wide temperature range, and is not afraid of harsh environments, ensuring stability and reliability.

6. High-Efficiency Conversion, Performance Assurance

The power amplifier working power supply and speaker protection circuit work together to build a wide dynamic range, ensuring maximum efficiency in electro-acoustic conversion, with stable and long-lasting sound output and lower energy consumption.
