Verco/Vulcraft Group - DoveTail Acoustical Values and Reports

Table 1: Noise Reduction Coefficients of Acoustical DoveTail Deck
Summarizes the sound absorption coefficients for acoustical DoveTail decks at a number of frequencies. It can be found on page 3 of the DoveTail Catalog. The noise reduction coefficient (NRC) historically reported is the average of the coefficients at 250, 500, 1000, and 2000 Hz expressed to the nearest integral multiple of 0.05. The sound absorption average (SAA) is the average of the sound absorption coefficients for the twelve one-third octave bands from 200 through 2500 Hz inclusive, rounded to the nearest 0.01. Testing was performed in accordance with ASTM C423-09a and ASTM E-795-05.

Table 1A: Sound Transmission Class (STC) & Impact Isolation Class (IIC) of Acoustical DoveTail Deck Assemblies
Summarizes the STC and IIC for DoveTail composite deck. STC is the assembly's ability to block sound from traveling through the floor system as a whole i.e. to stop airborne noise for transferring from place to place and the IIC is the assembly's ability to absorb impact sound i.e. footsteps on the floor. The DoveTail composite deck is part of the system shown and requires all parts to be present to use the values in the table. Testing was performed in accordance with ASTM E90 and E492. Evaluation criteria included ASTM E90-09, ASTM E413-16, ASTM E492-09, ASTM E989-06 and ASTM E2235-04.
