The Global Leader in Long Range Acoustic Hailing Devices

Fact Sheet

LRAD Corporation is using long-range communication to safely hail and warn, inform and direct, prevent misunderstandings, determine intent, establish large safety zones, resolve uncertain situations and save lives on both sides of its proprietary Long Range Acoustic Device® (LRAD®).

Most conventional loudspeakers disperse sound in all directions. LRAD’s proprietary audio technology focuses sound in a 15° – 30° beam in front of its Long Range Acoustic Devices, while significantly reducing audio levels behind the devices and in surrounding areas. LRAD broadcasts are safely optimized to the primary human hearing range of 1 – 5 kHz and can be clearly heard and understood from close range to over 5,500 meters.

LRAD systems broadcast live or recorded voice messages with exceptional clarity in any operational scenario. LRAD’s optimized driver and waveguide technology ensures every voice and warning siren broadcast cuts through crowd, engine, and background noise, and is clearly heard and understood, even inside buildings and vehicles.

In public security and defense applications, LRAD fills the critical gap between the limited range and poor intelligibility of bullhorns and vehicle P.A. systems, and kinetic measures including tear gas projectiles, rubber bullets, pepper balls, Tasers, and flash bang grenades. LRAD is not a weaponLRAD is a highly intelligible long-range communication system and the safer alternative to kinetic force.

LRAD’s omnidirectional ONE VOICE™ systems combine warning sirens and highly intelligible voice broadcasts to provide advanced mass notification and public address solutions. Traditional warning systems sound sirens, but are severely voice-challenged. LRAD mass notification systems safely communicate to crowds during large, outdoor events and to affected populations throughout emergency situations. LRAD systems are self-contained or easily integrated with existing communications infrastructure.

LRAD warning sirens are similar to police and fire sirens and are very effective in gaining attention to the voice messages that follow. Contrary to erroneous reports, LRAD is incapable of generating very low frequencies and does not cause nausea or disorientation.

LRAD systems are safe, rugged, reliable, easy to operate and can be temporarily or permanently mounted.

LRAD Corporation maintains a strict policy of selling LRAD systems only to qualified government agencies and commercial security entities. Operators are trained in the device’s operation and use before deployment.

By maintaining a smooth frequency response with an intensity variation of less than 5dB, LRAD has eliminated the shortcomings of competitor systems by preventing audio fading and producing clear, unambiguous communication across all broadcast frequencies.

Each LRAD model is the loudest, most intelligible product in its size and weight category. Additionally, LRAD features a portable capability in a rugged, lightweight waterproof casing, as well as wireless capability and the option to operate the device remotely across an IP-accessible network. LRAD provides communication solutions to meet any operational requirement.

How LRAD is deployed in public, law enforcement and defense applications:

Step 1 – Operator broadcasts directions/instructions in a loud, clear voice

Step 2 – If direction is not taken, operator then broadcasts a more authoritative message

Step 3 – If directions/instructions are not taken, operator employs the LRAD warning tone.

Step 4 – After employing the above steps, if individuals or crowds persist in unlawful actions, operators are assured they provided clearly heard and understood commands to cease and desist before initiating EOF.

LRAD Advantages:

LRAD systems clearly, effectively and safely communicate over distance, create large standoff zones, prevent misunderstandings, determine intent, alleviate uncertain situations, prevent injuries, and save lives on both sides of the Long Range Acoustic Device.
