SOURCE, PATH & RECIEVER Three components must be present for
noise to exist: Source Path Receiver TRANSPORTATION &
ENVIRONMENTAL NOISE MITIGATION
9 2013 Armtec Ltd. Confidential & Proprietary NOISE BASICS
Why Absorption? - TNM Software provides for sound absorption in
modeling, potentially reducing wall heights - Increased mitigation
performance at little extra cost - Parallel Noise Wall Applications
- Eliminate multiple reflections - Eliminate reflections to
associated receivers Why Double-Sided Absorption? - Community noise
generated on the residential side of the noise barrier is absorbed,
not reflected back to adjacent receivers. - Service
roads/arterials/ramps etclocated on receiver side of barrier -
Increased acoustical performance at no additional cost
10 2013 Armtec Ltd. Confidential & Proprietary NOISE BASICS
Source: Source is the defined location where sound/noise is
produced. Receiver: A Receiver is the defined location where
sound/noise is heard/impacted NOISE REDUCTION COEFFICIENT (NRC): An
arithmetic average of an acoustic material to the nearest multiple
of .05 of four sound absorption coefficients at frequencies of 250
Hz, 500 Hz, 1000 Hz, and 2000 Hz. An NRC of 0 = perfect reflection
and an NRC of 1 = perfect absorption. NRC is based on human speech
frequencies therefore providing a simple scale of how well a
surface material will absorb the human voice. MASS: The weight of a
given material in a given volume. Generally the heavier or denser a
material is, the more sound it will stop and the higher the
Transmission Loss (TL) will be. STC should be min. 30, with minimum
density of 4Lbs/sq ft. NOISE MITIGATION: Noise mitigation is a set
of strategies to reduce noise pollution. Solutions can include
walls, barriers, earth berms, zoning setbacks, zoning buffers,
etc
11 2013 Armtec Ltd. Confidential & Proprietary NOISE BASICS
Noise Reduction Goal The amount of noise reduction that is desired.
This value should be defined by a respective owner/DOT/State
Highway Agency and should typically be in the range of 5-10 dB(A).
Noise barriers must provide at least a 5-dB(A) reduction in highway
traffic noise levels in order to provide noticeable and effective
attenuation. A noise barrier should be designed to achieve the
greatest reduction possible, but in no instance less than 5 dB(A).
Properly-designed noise barriers should attain an IL approaching 10
dB(A), which is equivalent to a perceived halving in loudness for
the first row of homes directly behind the barrier. For those
residents not directly behind the barrier, a noise reduction of 3
to 5 dB(A) can typically be provided, which is just slightly
perceptible to the human ear.
12 2013 Armtec Ltd. Confidential & Proprietary NOISE BASICS
How Does a Noise Barrier Work? Noise barriers reduce the sound
which enters a community from a busy highway by either absorbing
the sound, transmitting it, reflecting it back across the highway,
or forcing it to take a longer path over and around the barrier. A
noise barrier must be tall enough and long enough to block the view
of a highway from the area that is to be protected, the "receiver."
Noise barriers provide very little benefit for homes on a hillside
overlooking a highway or for buildings which rise above the
barrier.
