I can send you a picture if you want....just E-Mail me.MOBILE ACOUSTIC SOURCE (MOAS)
"MOAS is located at the Blossom Point Research Facility, MD. It is a system with environmental capabilities that exist in no other system in the world. The MOAS is a pneumatic loudspeaker system that allows scientists to verify acoustic models with atmospheric effects. The system is a true exponential horn, 56-ft long, with full fidelity from 10 to 500-Hz. It will generate sound sufficient for testing acoustic propagation of sources up to 15-km away. Other features include the following: (1) it is transportable, mounted on an expandable flatbed trailer, (2) it can develop 20,000 acoustic watts of power, or over 150-db, and (3) it may be remotely controlled with fail-safe software to ensure safe operation. The MOAS can reproduce realistic signals simulating any sound at various ranges and under controlled conditions, and it can broadcast single tones, multiple tones, or tape playbacks."
