Press Release Summary = Sturgis Iron and Metal retained Acoustical Solutions to
assist in a continuous effort to "coexist" with the surrounding residential
community in Elkhart, Indiana. After the installation of the Mega-Shredder at the
Sturgis facility, Acoustical Solutions was brought in to perform additional sound
mitigation, including the design of a sound wall enclosure.



Press Release Body = Since the installation of the Mega-Shredder, the Sturgis
facility continues to attempt to improve environmental conditions for its
residential neighbors. Because sound has been one of the primary concerns with the
Mega-Shredder, Acoustical Solutions has been retained to provide additional noise
mitigation at the Elkhart facility. Acoustical Solutions has performed a site survey
of the shredder to obtain the information necessary to engineer a Sound Barrier
Enclosure that will effectively block and absorb noise created by the machinery.

Acoustical Solutions assembled a team of Acoustical, Civil and Structural Engineers
capable of taking on the project requirements and demands necessary to mitigate the
noise created by the shredder and occasional explosion of "LP-Tanks" (propane). The
shredder is capable of reducing cars to small shrapnel in a matter of seconds. The
LP tanks are sometimes overlooked in the trunk of cars sold to Sturgis for
recycling. When sent through the shredder unknowingly, the tanks cause a dangerous
unexpected release of energy. The type of release that occurs is commonly called a
Bleve (Boiling Liquid Expanding Vapor Explosion). The Bleve is a dangerous release
of energy, and if not controlled properly, the noise and vibrations caused by these
explosions irritate neighboring residents.

Acoustical Solutions is designing a Sound Barrier Wall that will block and absorb
the noise produced by the daily operation of the shredder. The engineering team will
also design a Blast Shield and Fragment Retention System to handle the accidental LP
tank releases of energy. The daily operation of the shredder cannot be obstructed by
the design and addition of the Sound Barrier Enclosure, Blast Shield or Fragment
Retention System. Acoustical Solutions will be on the project site May 23rd to begin
designs that will incorporate seamlessly into the Mega-shredder structure.

The Mega-Shredder is the world's largest automobile shredder. It is driven by an
8,000 HP AC Motor and is capable of processing as much as 400 tons of steel per
hour. The History Channel as part of its "Modern Marvel" series will feature the 130
Heavy Shredder. The televised premier is May 23, 2007.
