Your NRC is how much? An examination of PET product acoustics.
From November 2020, in this webinar targeted to architects, Jason Ehrlich reviewed room acoustics basics like NRC and Reverberation Time.
Then dissected a recent laboratory test report from the kleen lineup and discover how terms like Sabins might offer a better way to consider
suspended acoustical products. Lastly he did a quick acoustic comparison between the new PET products and other products that are specially
tuned to meet specific acoustic needs.
kleen Line of Products
From October 2020, Ben Hickey, National Sales Manager, introduced the kleen line of products. kleen features recycled PET, offering
ultra-low VOC emissions and bleach cleanability. The material is formaldehyde free and 100% recyclable. kleen balances acoustical design with an emphasis on
environmental wellness. kleen includes seven different cloud and baffle products, two wall coverings, and two dividers. With close to forty colors
to choose from, custom shapes and sizes, as well as cutout patterns available on many products, the design possibilities are endless. This presentation
will provide an overview of the products, as well as a short discussion on PET in general, including acoustics.
Duct Silencers – Types, Performance and Proper Application
From September 2020, Airborne noise generated from HVAC equipment is a concern in commercial and industrial buildings. Duct system components allow the sound to
transfer from AHU/RTU’s along both supply and return air paths to critical occupied spaces. The most common, cost effective method to control
this noise to acceptable levels is to design proper duct silencers within the air paths. In this 30min webinar, Kristen Neath discussed duct silencers,
their use, proper application and performance characteristics in this 30 minute overview.
Home Theater Acoustics
From July 2020, Jason Ehrlich, Strategic Marketing Administrator, delivers a brief introduction of Home Theater acoustics. Home Theaters are a challenging
environment to tune due to the broad frequency of sound not found in other environments. Jason looks at some of our "music rated" absorbers,
explore a list of materials typical of a theater, and look at a professional package where room treatment has been laid out specific to the
selected audio equipment.
Vibration Isolation for Mechanical Systems
From August 2020, in this 20 minute webinar, Lee Chiddention gives an introduction to mechanical system vibration isolation. This brief presentation focused
on Vibration isolation Selection, ASHRAE isolation types, briefly covered in-curb acoustical treatments, and concluded with how Kinetics can assist
with delegated design and certification.
Concrete Noise Control Construction: Spring hangers for Isolated Ceilings
From May and June 2020, in this 20 minute prerecorded webinar, Jason Ehrlich discusses the features of various spring hangers used in concrete construction. He looks at an
interesting series of acoustical tests that were fun using a 6" concrete slab and the same hanger. Finally he tours a new product page and
reviews new tools that are available to designers.
Air-Cooled Chiller Composite Noise Control Solution
From June and July 2020, Noise emanating from air-cooled chillers into critical areas: screw compressors (bottom sides of unit) generate mid/hi frequency
noise; up-blast fans (top of unit) generate low/mid frequency noise. A common approach is to control noise from only one of these noise sources.
Kinetics offers engineered solutions to control noise emanating from both sound sources, taking into account proper equipment operation, maintenance access
and aesthetically pleasing appearance. Listen to this 20-min, prerecorded webinar, by John Sofra to learn more.
In-plant/Facilities | Engineering Controls Solution
From April 2020, in this 20 minute webinar, John Sofra presents a Kinetics engineered control solution for manufacturing process workplace sound reduction.
The solution examined required noise reductions of 105 dBA to 85 dBA at 19'-0" from a tongue and groove machine, and 101 dBA to 85
dBA at 5'-0" from a sander machine.
Noise Rated Ceiling Tiles
From April 2020, in this 20 minute webinar, Jason Ehrlich discusses Noise Rated Ceiling Tiles. Walls are often blamed for noise problems when the
real culprit might be the ceiling. He details the current product offerings for noise-rated acoustical ceiling tiles while giving an
overview of related acoustic terms.
