Traditional bird deterrent methods either have limited coverage or are easily adapted to by birds, significantly reducing their effectiveness. In contrast, Shenzhen Zhenqu Bird Technology's ZQN-DL-QS High-Power Intelligent Voice Bird Deterrent Device employs "sound" as its core weapon. Through scientifically designed powerful sound waves and specific audio effects, it continuously disrupts birds at the auditory level, achieving contactless, wide-area, and long-lasting bird deterrence, establishing an invisible acoustic barrier for power grid safety.

80-100 decibels of auditory deterrence
The auditory system of birds is far more sensitive than that of humans. Sounds at specific decibels and frequencies can directly stimulate their auditory nerves, triggering alertness and flight responses. The high-power intelligent voice bird repellent device for power grids capitalizes on this physiological trait by precisely controlling sound parameters to achieve scientific bird deterrence.
1. Decibel threshold: Triggers discomfort in birds
Research indicates that when sound intensity reaches 80-100 decibels, birds experience significant auditory discomfort. An 80-decibel warning signal prompts birds to become alert and slow their approach. At 100 decibels—equivalent to a tractor starting—birds exhibit pronounced auditory distr decibels, birds experience significant auditory discomfort. An 80-decibel warning signal triggers initial alertness, causing birds to slow their approach. At 100 decibels—approaching the noise level of a tractor starting—the auditory nerves of birds become markedly compressed. This triggers a perception of a hazardous environment, prompting them to abandon plans to linger or nest and flee rapidly.
ZQN-DL-QS employs high-power speakers to maintain sound intensity within the stable range of 80-100 decibels. This ensures effective bird deterrence while prioritizing ecological friendliness, preventing excessive harm to avian species.
2. Frequency Range: Precise coverage from 150Hz to 4kHz
Different bird species exhibit varying sensitivity ranges to sound frequencies. The high-power smart voice bird repellent device for power grids is set to emit frequencies between 150Hz and 4kHz, effectively covering the auditory sensitivity zones of most common birds found near power grids, such as magpies, crows, sparrows, and pigeons:
Low-frequency band (150Hz-500Hz): Designed for larger birds such as magpies and crows, whose low-frequency sounds travel long distances with strong penetration. This frequency range can deter them from approaching transmission towers at considerable distances.
Mid-to-high frequency range (500Hz-4kHz): For smaller birds such as sparrows and pigeons, mid-to-high frequency sounds more readily stimulate their auditory nerves. Even during group activities, these frequencies effectively disperse flocks and prevent nesting within substations.
This wide-frequency coverage design enables the device to handle diverse bird species around power grids without requiring parameter adjustments for individual birds, thereby reducing operational complexity for maintenance personnel.
