High-Sensitivity Acoustic Detector for Rubble
1. Search and rescue in earthquake and building collapse rubble; captures vibration signals from survivors' knocking, shouting, etc.
2. Automatically filters environmental noise such as wind, machinery, and vehicles; accurately distinguishes human distress signals.
3. Coordinated detection by 4-channel sensors; combined with bar charts to intuitively determine the location of trapped personnel for precise positioning.
4. Supports two-way intercom; allows communication with trapped personnel under rubble and recording of on-site sounds.
5. Suitable for complex rescue scenarios such as rubble, snow, and loose ground; probes support wireless long-distance deployment.
6. Long battery life; equipped with a stand for continuous search and rescue operations in field and disaster sites.

Mainly used for earthquake rubble rescue to listen to underground sounds, capable of identifying any human-generated sound in rubble, such as shouting, slapping, scratching, and knocking; can filter surrounding background noise to help rescuers locate survivors seeking help
1. Integrates vibration signal listening with voice communication; enables precise positioning of trapped persons; high probe sensitivity.
2. ▲10-inch touchscreen host with built-in electronic manual.
3. Supports shouting, recording, and playback functions; recording duration ≥1 minute
4. ▲Features bar chart display function, converting listened vibration signals into bar charts and clearly distinguishing signal sources
5. ▲Number of audio-vibration sensors: 4 channels, capable of detecting audio-vibration signals from human hand-to-ground knocking within a 20-meter range; wireless transmission distance between probe and host ≥50 meters
6. Each audio-vibration sensor is equipped with 1 magnetic suction cup and 1 metal probe, suitable for harsh environments in collapsed buildings, loose ground, and snow-covered areas.
7. ▲Audio-vibration sensor frequency detection range: 0Hz-5000Hz.
8. Automatic adjustment of high-frequency and low-frequency filters: automatically filters out non-target noises such as demolition tools, vehicles, wind, and high-voltage cables.
9. Voice intercom probe: Built-in microphone and speaker, enabling two-way communication with trapped persons; audio pickup range ≥180㎡.
