Singapore Changi Airport has ordered another Long Range Acoustic Devices (LRAD) system from protective communications developer Genasys. The LRAD is a “bioacoustics deterrent,” according to San Diego-based Genasys, and Changi has employed the system since 2021 to prevent bird strikes with aircraft during takeoff and landing.

Genasys has already deployed LRAD systems at other Asia-Pacific (APAC) airports and is “working several pipeline opportunities to protect jets, passengers, and wildlife in the APAC and European regions,” according to David Schnell, v-p global hardware sales at Genasys. The annual cost of bird strike aircraft incidents is estimated at $1.2 billion.
