R-STC Silencers Applications
Price R-STC silencers are designed for
medium-low velocity applications. This
medium-low velocity configuration provides
the highest insertion loss levels across the
full range of frequencies. With a sloped tail
arrangement providing static regain for
improved pressure drop, these silencers are
best suited for application with velocities
1000 fpm or less. |

R-STC |
Price R-STC Silencers have been designed
to provide noise reduction performance
meeting STC 40, 45, 50 and 55 ratings, and
as required, include a high transmission
loss casing with double wall construction
to maintain the acoustic integrity of the
unit. An STC rating is a single number value
indicating the sound isolation properties of
a wall. A specific STC Rating is commonly
specified for the wall construction between
adjacent acoustically sensitive rooms, such
as police interrogation rooms and sensitive
military applications. The STC rating of the
R-STC silencers has been determined based
on insertion loss performance obtained
from ASTM E477 and rated according to ASTM 413.
