LRAD Corp. sends six Long Range Acoustic Devices to Colorado National Guard for flood relief efforts

Colorado National
Guard responds to
floods in Boulder

LRAD Corp. has announced that it has sent six Long Range Acoustic Device systems to the Colorado National Guard for land- and air-based communication to broadcast critical information and instructions to those affected by the catastrophic flooding in northern Colorado.

According to the company, the LRAD systems were first used for disaster relief in the aftermath of Hurricane Katrina to communicate to survivors stranded on the tops of cars and houses by flooding, and for mass notification around the Superdome.

In 2010, the U.S. military utilized several LRAD systems in Haiti to assist with emergency communications with earthquake survivors. Portable LRAD 100X systems were used to communicate in multiple languages to survivors gathered around aid stations, and helicopter-mounted LRAD 500X systems were used to broadcast the locations of aid stations and supplies across severely damaged areas.

In 2011, Japanese disaster relief authorities used LRAD 100X and LRAD 500X systems for mass communication and to coordinate search and rescue operations after the devastating earthquake and tsunami. In 2011 and 2012, Thailand’s department of disaster response deployed LRAD systems to support flood relief efforts.

The company indicates that additional systems are in the process of being installed for emergency warning and mass notification (EWMN) and integrated into tsunami and earthquake warning networks. Additional installations are being planned.

The company points out that in natural disasters, existing infrastructure is often disrupted or compromised, power and communications frequently fail and personal contact can become difficult. Rural areas may also become isolated and urban areas impassible and dangerous. In these situations, communicating evacuation orders, conducting search and rescue operations and providing lifesaving information can become highly problematic.

The systems provided by LRAD provide National Guard personnel and civilian authorities a highly effective, long range communication capability to clearly broadcast critical information, multi-lingual instructions and warnings into disaster-affected areas over distances of 200 yards to over 2 miles in any type of environment and terrain. Ground-based and helicopter-mounted LRAD systems are used to warn of pending disasters, communicate to disaster-isolated neighborhoods and towns, conduct search and rescue orders over large areas, direct survivors to aid stations, warn of contaminated water supplies and other critical information.
