][2.3.6
Acoustical Steel Deck
**************************************************************************
NOTE: A noise reduction coefficient of 0.70 is a
commonly used coefficient. The coefficient can also
be obtained from manufacturer's literature.
However, specific design requirements must be
considered and the appropriate value inserted. The
manufacturer's standard acoustical steel deck shall
be provided where indicated.
**************************************************************************
Provide a Noise Reduction Coefficient (NRC) rating of not less than [0.70]
[_____], when tested in accordance with ASTM C 423, Standard Mounting No.
6. Sound absorbing materials shall be either [glass fiber in roll or
premolded form for acoustical steel deck (noncellular)] [and] [or] [glass
fiber rigid strip for acoustical steel deck (cellular)] in accordance with
manufacturer's standards. The Contractor shall comply with EPA
SECTION 05310
