Background & Demands

In the face of disasters such as earthquakes, mining accidents, and explosions that leave people trapped, traditional search and rescue methods are inefficient and high-risk. To quickly and accurately locate survivors within the "golden rescue window," life detection devices have emerged.

I. Disaster Emergency Response

• 1. Earthquake Disasters
• Scenario Description: Earthquakes cause large-scale building collapses, forming complex rubble structures, with many people buried beneath the debris.
• Application Value: Rescue personnel use audio life detection systems. Through their highly sensitive sensors (microphone arrays), they can capture sounds made by buried individuals, such as calls for help, moans, or tapping on pipes or walls. Even under several meters of rubble, they can accurately locate survivors, buying valuable time for rescue within the "golden 72 hours.

• 2. Mining Accidents & Tunnel Collapses
• Scenario Description: Mine cave-ins, tunnel construction accidents, etc., lead to people being trapped in deep, dark, and structurally unstable underground spaces.
• Application Value: The environment contains complex background noise (e.g., dripping water, loose rocks). Audio life detection systems can filter out background noise, specifically identify and amplify rhythmic tapping or shouting from trapped miners, guiding rescue teams to dig in the correct direction.
• 3. Explosion Attacks & Building Explosions
• Scenario Description: Gas explosions, bomb attacks, etc., cause partial or total building collapse, creating chaotic scenes.
• Application Value: Quickly search the rubble for potential survivors, especially those who are injured and unable to call out loudly but are still conscious and can make faint tapping sounds.

II. Accident Disaster Sites

• 1. Traffic Accidents
• Scenario Description: Train derailments, large buses overturning and being buried, or vehicles falling into valleys and being obscured by vegetation.
• Application Value: Within wreckage that is difficult to quickly dismantle or clear, confirm the survival status and specific location of survivors by detecting their sounds, enabling precise rescue operations.

III. Security & Law Enforcement Operations

• 1. Hostage Situations & Counter-Terrorism Operations
• Scenario Description: SWAT teams have surrounded a building containing suspects and need to ascertain the location, number, and status of people inside, where a direct assault could pose significant risks.

• Application Value: Law enforcement officers can covertly place the detection system against walls, windows, or ventilation ducts to monitor conversations, footsteps, or breathing sounds inside. This helps determine the real-time locations and emotional states (e.g., nervous pacing) of hostages and captors, providing critical intelligence for planning raids.
• 2. Border Patrol & Drug Interdiction
• Scenario Description: Suspected stowaways or drug traffickers hidden in containers, truck compartments, or secret rooms.
• Application Value: Without alerting the suspects, use the detection system to monitor whether there are human breathing sounds, coughing, or subtle movements inside, serving as a basis for further inspection actions.

IV. Special Search & Rescue

• 1. Search for Missing Persons in Wilderness
• Scenario Description: People get lost in dense forests, canyons, or complex mountainous terrain where visibility is low, making traditional searches inefficient.
• Application Value: Search teams can deploy detection systems in suspected areas to listen for possible response sounds from the missing person. Its directional capability can help narrow the search area, especially at night or in conditions with poor visibility.

• 2. (Limited Scenarios) Avalanche Rescue
• Scenario Description: Skiers buried by avalanches.
• Application Value: Although avalanche beacons are more mainstream technology, in some cases, if the buried person is conscious and can make sounds, an audio life detection system can serve as an auxiliary tool, used in conjunction with probes and other equipment.

Core Advantages：

• High Sensitivity: Capable of detecting extremely faint life signals.

• Accurate Direction Finding: Helps rescue personnel determine the direction and approximate depth of the sound source.

• Non-Contact Detection: Allows for locating survivors without direct contact, ensuring the safety of both parties.
