TBS and Genasys at the Forefront of Acoustic Safety and Security Technologies

TBS Ltd., in partnership with Genasys Inc. (USA), successfully conducted a live demonstration of advanced acoustic communication and deterrent systems – the LRAD 450XL-RT and LRAD 950NXT – at Plovdiv Airport on 13 November 2025. The event presented the exceptional capabilities of the systems in supporting modern approaches to safety, security, and crisis communication across critical infrastructure and aviation environments.

The demonstration was attended by representatives from the Bulgarian Air Force, including the 3rd Air Base – Graf Ignatievo, the 24th Air Base – Krumovo, and the Air Force Command, as well as by the directors of the Airport Operations Centers (AOC) of Burgas and Varna Airports, and representatives of Plovdiv Airport’s Security and Safety Departments, who were the hosts of the event.

The participants were introduced to the broad range of applications of the LRAD systems – from security enforcement, access control, and crowd management, to emergency communication and wildlife risk mitigation in airport environments. The demonstration highlighted the systems’ ability to deliver clearly intelligible voice messages and deterrent tones over long distances, ensuring reliable communication in complex operational scenarios and adverse conditions.

Developed by Genasys Inc., a global leader in protective communications, the LRAD technology is deployed at numerous strategic facilities worldwide as part of integrated safety and security systems for early warning, evacuation management, and incident response. The showcased models – LRAD 450XL-RT and LRAD 950NXT – combine precision acoustic performance with remote control capabilities and seamless integration with sensors, video surveillance, and monitoring platforms.

Plovdiv Airport, as host of the demonstration, reaffirmed its proactive approach toward implementing innovative technologies that enhance safety, operational efficiency, and emergency preparedness. The event underscored the importance of cooperation between technology providers, infrastructure operators, and public authorities in building a secure and resilient aviation ecosystem.
