News & Accomplishments
- The outdoor sound group continues to be closely integrated with the infrasound group. Organizationally, the group consists of three scientists who primarily develop software to support outdoor sound simulation and in addition, support other research and development efforts within the laboratory.
- The primary effort of the outdoor sound group continues to focus on the development of the acoustic module for the U.S. Army’s Hostile Fire Detection System (HFDS) simulation environment. This environment is a large scale computer simulation of the physical “world” experienced by helicopters and tracked vehicles. The Army’s goal is to be able to simulate the performance of potential sensor systems prior to acquisition. One part of this is the acoustic environment created by the vehicle; the other part is sound created by weapons. The motivation for acoustic simulation is that acoustic sensors can be used to detect the ballistic shock wave created by supersonic projectiles that pass near a vehicle and the blast wave produced by the firing of a weapon; thus providing a means for detection and locating hostile ground fire.
- Other efforts have involved or currently involve supporting UM Electrical Engineering in development of technology for assisting stuttering patients, and the development of helicopter noise control, prediction and propagation software for the U.S. Navy.
