Overview
The Long Range Acoustic Device (LRAD) is a high-powered acoustic system functioning as an amplified bullhorn capable of emitting ear-piercing noise for crowd dispersal and long-range communication.
Operational History
Marines in Iraq were already using LRAD systems at the time of Project Sheriff's development. The device had proven operational utility in urban combat environments.
Controversy
Critics raised concerns that the ear-piercing acoustic output could cause permanent hearing damage or deafness. Despite these concerns, Col. Wade Hall noted that "the office has no alternative if it is not picked" for Project Sheriff integration, indicating LRAD was considered essential to the system's capabilities.
