Sound Curtains
Sound Curtains offer maximum sound control and noise reduction using a combination
of sound absorption and noise barrier material. Clients refer to our product as sound curtains, noise
curtains, sound blankets, or hanging quilt blanket. Our sound curtains are modular, velcro sealed, noise
control curtains that are effective, rugged, and industrial grade in construction.

Acoustic blankets are used in many industrial, commercial and OEM noise control applications. The
system can accommodate ventilation and access while maintaining high noise control. Curtains are
easy to install and can be moved for use in another location to accommodate machine or equipment relocation.
Sound curtains can provide a permanent, yet flexible, solution to your unique noise control situation.
Our staff can help engineer the right system for your sound reduction goals.

Typical Sound Curtain Applications
-
Compressor noise control
-
Hydraulic pump enclosures
-
Outdoor sound blanket applications
-
PD blower sound curtain partitions
-
Outdoor fence construction
-
Many industrial noise control HVAC projects
Years ago, industrial engineers labeled the product as a lead blanket. Lead has been replaced
by a safer environmental noise reduction mass loaded vinyl. eNoise Control can offer many enclosure or sound
wall options for your sound proof application. Please call or email us today for design and price quote.

The National Institutes of Health describes noise-induced hearing loss as the
result of one-time exposure to a damaging loud noise, or as the result of ongoing
exposure to a loud environment. In most cases, on-site workers have ear protection,
but those around them do not. Noise pollution can affect downtown offices,
commercial spaces undergoing construction and sound studios.
How Sound Curtains Work
Sound curtains form a flexible barrier between sources of noise and living or working
spaces. They work on two principles: absorption and redirection. Sound waves move
through air much in the same way that ripples move through water. Like ripples in
water, sound waves become disrupted when they encounter a barrier. The shape of that
barrier affects how waves behave. The quilting on our vinyl-coated sound curtains forms
multiple curved surfaces that redirect sound waves. As they bounce off the vinyl
surfaces, sound waves lose their coherence and are rendered harmless.
Fiberglass quilting bonded to a vinyl barrier forms a second layer of protection from
noise. Like insulation in a permanent wall, the batting within sound curtains absorbs
sound waves and creates a quieter environment. A thick layer of padding reduces noise
pollution with minimal bulk. While redirected sound waves lose their coherence, absorption
reduces the overall level of sound. Choose a preferred thickness based on the degree of
noise pollution.
Flexibility
Sound curtains differ from permanent noise-reduction installations in their flexibility.
While they can present a permanent solution for noise reduction, soundproofing curtains
also travel where they're needed and store out of the way when not in use. For office
buildings and commercial spaces that are undergoing renovations in stages, movable
soundproofing isolates the worksite no matter where the workers are located. They also
can create a temporary sonic barrier around an enclosed space for meetings or break rooms
on construction sites.
Unlike permanent walls, modular soundproofing curtains do not disrupt air-flow or limit
access to soundproofed zones. Velcro closures make moving through the auditory barrier
simple for equipment and personnel. An installation of sound curtains that surrounds
noisy equipment can retract when that equipment is not in use, providing additional
work space and allowing air to circulate freely.

Options
Our sound curtains are available in solid form and with windows to admit light into
the work space. Like the vinyl coating on the acoustical curtains themselves, the
clear windows can withstand indoor or outdoor use. The window material is 1 pound
per square foot flexible vinyl barrier. Because sound curtains rely on redirection
as well as absorption, windows do not significantly reduce the efficacy of the
soundproofing materials.
A range of colors enables you to select acoustical curtains that will blend in with
their surroundings. Gray, white, black or tan curtains look unobtrusive enough for
commercial applications such as coverings for mall storefronts while construction is
underway. Black soundproofing has theatrical applications to keep backstage areas
and lighting booths silent, while white soundproofing ensures that outside workplaces
remain as cool as possible for the workers inside.
Available ventilation
baffles keep curtained spaces acoustically isolated while retaining their airflow.
Equipment that requires airflow can continue to operate safely, while workers remain
comfortable. Choose passive ventilation panels to ensure regular airflow or use
forced-air ventilation systems to keep electronic components and high-temperature
machinery cool.
Sound curtain material also is available in 4-foot-wide rolls as well as in pre-formed
panels. Roll edges may be bound or unbound to allow complete customization of the work
space.
