Yes, indeed, things are changing with the rising cost of fuel, energy and raw materials. However, IAC believes strongly in the business model for turnkey noise control solutions in both new and existing applications here in the Americas. With greater volume, comes greater opportunity in making the world a quieter place. Keep up the good work and enjoy the stories. Best Wishes. Kenneth DeLasho
Located in the heart of Manhattan overlooking the Empire State Building the JBI Library contains the largest collection of Jewish interest books (very broadly defined) for the blind and visually impaired in the world and is the only resource of its kind and its programs benefit over 35,000 people worldwide.
There were a number of challenges and ‘firsts’ with this contract. This was the first application where IAC has utilized the full height fabric panels, floor-to-ceiling, instead of the conventional enhancement arrangement featuring the chair rail and perforated steel liner panels. To further complicate this unique fabric panel design, the institute required surface mounted microphones and other associated equipment. To incorporate this into the full fabric panel design, IAC provided a solid steel hat section and the appropriate custom fabric panel cutouts that allowed the proper structural mounting of the equipment to the metal panel shell.
The JBI Library provides the visually impaired, blind, physically handicapped and reading disabled of all backgrounds and ages with books, magazines and cultural programs in Audio (in seven languages), in Large Print and in Braille. It offers a collection ranging from mystery novels to cookbooks to timely topics such as the production of biological weapons. It also offers a broad spectrum of fiction, biography, history, Holocaust studies, short stories, psychology and self-help, memoirs, humor and more. An Affiliated Library of the Library of Congress, all of its services and materials are provided free of charge. Special thanks to the IAC Architectural Team/People Environments and IAC technical representatives Mr. Bob Schmitt and Mr. Steve Dutton of QuietStar Industries for a job well done!

IAC NORDIC REFURBISHES ANECHOIC CHAMBER FOR VOLVO, SWEDEN
Prior to the refurb, the facility had essentially free field acoustical properties, due to a deep layer of mineral wool on the ceiling and walls. Sound data was obtained by using a pre-defined, standardised cluster of microphones. Now, IAC’s patented metal-clad Metadyne® wedges line the chamber providing a bright, pleasant environment. They are easy to clean should oil spills occur and maintain their acoustical performance as well as their appearance for 20 years or more. This test cell provides an acoustical environment that is certified to ISO 3745 with a 100 Hz cut off frequency.

IAC AMERICA’S LABORATORY TESTS ‘FOR FUN AND PROFIT’
For many years IAC America’s Aero-Acoustic Laboratory has been -and still is - used to develop the many products we are familiar with. We have recently been promoting the use of our aero-acoustic laboratory to test products ‘for fun and profit’.
Supporting a renovation at a music centre in the city, a local acoustical consultant asked us to measure the absorption characteristics of the existing theater seats as well as those of the new seats that were to be used for the renovation. IAC America’s Laboratory Testing Service not only allows us opportunities to cultivate good relationships with acoustic consultants but it also helps us to keep our ears to the ground regarding the events and developments in the acoustical world.

IAC’s European manufacturing capabilities have been exceeded due to an upsurge in demand from the power market, worldwide, principally from GE which is rapidly expanding its diesel and gas turbine operations on 5 continents. Fifty-percent owned by IAC, and fifty percent by IAC’s previous Hong-Kong based company, IAC China Holdings will operate from a new factory in Dongguan in Guangdong Province, in South China. Dongguan is one of the world's fastest growing cities with 6.5 million inhabitants. It is the home to over 15,000 international companies. IAC’s workforce at the new factory is set to more than double from 110 to over 250 and the old factory will be complemented by a new 48,500 sq ftfacility. Olivier Darrieus, General Manager of IAC Boet Stopson in Europe, is Chairman of the new company, assisted by Fred Zhang – a Chinese national – as General Manager and Vic Fang as Sales and Engineering Director. Brian Quarendon, IAC Group President said: “This new development is hugely exciting enabling us to maintain our lead supplier position with GE globally and to court additional business in Asia and the Pacific Rim. The new factory will be fitted with the latest machine tooling and our training programmes will result in a workforce second-to-none. We anticipate considerable growth in global business as a result of this new company formation.”
The VDE, Association for Electrical, Electronic & Information Technologies, was founded in 1893 and has evolved into one of the largest technical and scientific associations in Europe. They currently have over 34,000 members, including a broad spectrum of engineers, scientists, technicians and some 5,000 students.
The Chamber has a cut-off frequency of less than 80 Hz. It was built using a double wall panel construction yielding an ambient noise level of below 12 dB(A).
Volker Horchens is General Manager of IAC Germany: “VDE chose IAC because of our good support in the planning phase and the technical solution we proposed. We were delighted when following the testing and approval of the chamber by the PTB - the Physikalisch Technische Bundesanstalt - they described it as "one of the best Anechoic Chambers in Europe”.” The photographs were taken at the Grand Opening of the facility and show the various testing capabilities. IAC is a world-leader in the design and build of anechoic test chambers.

BMW NORTH AMERICA HQ GETS IAC ROOF-TOP BARRIER
When BMW announced the expansion of their North American Headquarters, renowned Architects HOK were tasked with creating a home for the North American Research and Engineering Center and Technical Services Group. This would include state-of-the-art technology with a careful eye on ensuring the facility would be environmentally and aesthetically compatible with bucolic Woodcliff Lake, NJ. A key criterion was acoustical compatibility with the community – rural in nature yet surrounded by many lovely homesteads. The design team also recognized that the Research and Development facility would require support from many large and noisy pieces of equipment – almost all to be located on the building roofs.
Another feature – the IAC system was already designed to withstand wind loads specified in the International Building Code with a post spacing of 16’ – which also matched the vertical lines of the buildings facades.
Task in hand - Bob Schmitt of QuietStar Industries, the IAC Technical Sales Representative for the greater New York area, immediately enlisted the expertise of IAC R&D, Engineering, and Manufacturing to develop the concepts and details that would satisfy HOK’s objectives. Designs were vetted – prototypes built – and the team concluded that the Noishield Barrier product line could indeed satisfy all of HOK’s objectives. As a result of this up-front effort IAC was well prepared to offer the project General Contractor a best value proposal for the supply and installation of three custom Noishield® FS/S Barriers on the rooftop of the R&D and Technical Services Buildings. And, as a result, BMW is now conducting full operations in a state-of-the–art research facility with all of the attendant noise producing machinery having been effectively attenuated by IAC Noishield Barriers to community standards. Our thanks to the Architectural team/Acoustic Treatments at IAC America and the IAC technical sales representative Mr. Bob Schmitt of QuietStar Industries in New Jersey for a job well done!

I am pleased to report that IAC has completed the first half of 2008 with great success. I attribute this to the people of IAC, our Representatives and Customers and encourage everyone to focus on our accomplishments.
IAC was contracted by the BR Fries Construction Company to design, fabricate and install six AccuTone2 Series translation booths for their recording studio. Three of the six were NIC-53 type booths with a 1”-thick interior fabric panel enhancement package while the other three were NIC-60 type booths with a 4” thick interior fabric panel enhancement package. All six booths were also outfitted with over-sized acoustic viewing windows to provide the translators with a much more open feel within the space. 
Integrating these unique features presented several challenges to our engineering and design team, including an elevator too small to carry a typical panel! In the end, including a few trips up the stairs by our dedicated installation technicians, all hurdles were successfully overcome.
The main requirements were to install a new engine dynamometer for today’s higher performing engines; improve the test cell acoustics; and not least the creation of a modern functional environment - aesthetically-pleasing as well as practical. 
“The ability to measure low sound levels at the engine was part of the requirement,” says Philip White, IAC Nordic’s Business Manager, “So we had to reduce noise from the dynamometer machinery and controls in the adjoining room. We installed a soundproof partition wall with a specially-designed wall wedge with silenced shaft penetration. Inside the test chamber, a dynamometer shaft cover with anechoic properties was installed in order to maintain free-field properties near the engine and measurement microphones.”
Architects and acoustical engineers often need to know the sound absorption properties of materials used in theaters to determine acoustical quality of the performance space. Items such as carpet, curtains and chairs significantly affect the parameters such as reverberation time, diffusivity and first reflection time. 
The new Semi Anechoic Chamber (SAS) is part of the VDE’s new EMC and acoustic test centre. It is one of the best known testing and certifying institutions in Europe.
IAC supplied the whole turnkey project. This included the vibration insulation of the inner shell which is mounted on springs. The floor is a concrete plate which also forms the base for the inner shell while the outer shell rests on the building’s foundation. The overall size of the chamber is 51ft x 44ft x 25ft high with the interior lined with IAC’s patented metal-coated Metadyne wedges. 
More than 4,000 participants attended the event which was jointly organized by the Acoustical Society of America, the European Acoustics Association and the Société Française d’Acoustique.
IAC’s new distribution agreement with Welan Technologies in Pune, has taken us straight to pole position as lead supplier of Anechoic Chambers to the Indian automotive industry.
Welan Technologies approached IAC following our design input for a leading test house last year. IAC assisted the lead consultant to NATRIP – the Indian government department – in the development of seven centres of automotive excellence across India. 
Nitin Welanker BSc MSc PGDMM MDFT is CEO of Welan Technologies. He has over 24 years’ experience in the automotive sector, and formerly representing B&K the name in noise control instrumentation. He said: “I first contacted IAC in late 2007 recognising that IAC technology is simply the best in the world today. With my extensive knowledge of market and personal contacts at senior levels throughout the industry, and IAC’s excellent products, I look forward to a long and mutually-rewarding relationship in the years to come. India is almost a virgin market for the chamber business and together with IAC we would like to fully exploit it.”
BMW’s North America Corporate Headquarters is to receive an IAC Roof-Top Barrier system to protect the local community against noise from air conditioning units. 
HOK opted for the exceptional sound absorption and sound transmission loss capabilities of the IAC Noishield Barrier product. Construction details that included a non-welded assembly with a full 5” thick layer of sound absorption material, a powder coat finish, and horizontal reveals providing full length panel drainage on 24” vertical centers, would ensure the system be maintenance-free for well over 20 years.
However, HOK wanted to take the project to a higher aesthetic level and challenged IAC to improve the existing system. Specifically we had to find a way to fully conceal the flanges of the structural support system – in essence, to create the visual of a continuous, post-free wall nearly 300 ft long that closely aligned with all other vertical elements of the building façade.
