SECTION 09800
ACOUSTICAL TREATMENT
NOTE ** This section is based on Eckoustic(R) Functional
Panels (EFPs) as manufactured by:
NOTE ** Eckel Industries, Inc.
NOTE ** Acoustic Division
NOTE ** 155 Fawcett Street
NOTE ** Cambridge, MA 02138-1111
NOTE ** Tel: (617) 491-3221
NOTE ** Fax: (617) 547-2171
NOTE **
NOTE ** Eckoustic Functional Panels are high performance
sound-absorbing panels that can be spot located on
walls or ceilings to achieve effective noise
control. Because they are independent panels, EFPs
can be put into place without disturbing existing
lighting or HVAC diffusers. Attractive, fire
resistant, durable, and easily cleaned, they are
ideal for correcting noise problems in gymnasiums,
swimming pools, auditoriums and theaters, and
similar facilities. They also are appropriate for
industrial noise control use in water and waste
water treatment facilities and power plants as well
as manufacturing facilities.
