The Masters of Sound Absorption
Teams up with Grzegorz Sznyterman
We have been working for quite some time with Grzegorz Sznyterman (G.S), a company that specializes in all aspects of acoustical treatments for specific applications. We are now partnering with them in order to offer our customers acoustical simulations specific to their applications and needs.
G.S. specializes in acoustical consulting, design and specification for spaces and partitions (i.e., walls, ceilings, floors, doors, windows, etc.). They select from the full range of available acoustical products (i.e., fiberglass, wool, melamine foam, cellulose spray, etc.) to design their systems and then complement them with a wide variety of finish products, such as NEW/ACOUSTIC or NEW/TEXTIL, etc. The final product provides the precise acoustical absorption or reflection required by the client. All work is executed in compliance with the standards and legal requirements of the country in which the work is conducted.
They take pride in their many successful installations for residential buildings, shopping centers, offices, multifunctional auditoriums, and opera / concert halls, to name just a few types of these applications.
G.S. is very flexible and like new challenges, which is why they custom-design various solutions to meet the client’s needs, working with them from inception to final product, all while deepening their knowledge and awareness of acoustics. They cater to:
• architects working on new projects that require acoustical performance
• interior designers preparing interesting and unconventional rooms for a demanding client
• anyone who is affected by excessive noise in his or her apartment or workplace
• professionals who need to measure the acoustical performance in a space for proper soundproofing
G.S. has created a brand called “Architectural Sound” to make any space more comfortable and inviting. They know perfectly well that each one of us subjectively perceives sounds coming from the world around us. Architectural Sound is composed of a group of experts who specialize in the field of interior acoustics, architecture and interior design, stage systems, and concert performance acoustics. For many years, they have been cooperating with a team of scientists from the Laboratory of Technical Acoustics at AGH University of Science and Technology in Kraków, raising their standards and qualifications, exploring new solutions, and meeting various challenges together.
The modern world is surrounded by noise at every turn: at home, at work, at school, at the pool and in the fitness club – even in waiting rooms. Excess noise adversely affects our health, worsens our well-being, does not allow us to focus, and is very often the cause of decreased employee productivity. It makes conversing in restaurants difficult and loud concerts deafening. We all have had experiences like these, but we can change them!
For our proposed acoustical simulation with our NEW/ACOUSTIC or NEW/TEXTIL products, we offer:
• technical consulting for architects and acoustic designers in the field of room and wall soundproofing, as well as a selection of acoustic solutions that can be simulated with specialized software that allows you to “listen” to the designed interior
• acoustic measurements before and after completion of the work, analysis of results, measurements of acoustic insulation of building partitions from airborne and impact noise, measurements of noise and acoustic parameters of interiors – including special (unusual) rooms, measurements of speech intelligibility, tuning of electroacoustic systems, and measurement and tuning of audio systems in control rooms
• interior design projects with the implementation of acoustic solutions and visualization, providing a selection of acoustic ceiling and decorative wall panels, also with individual shapes and graphics, lights, etc.
• delivery and assembly of systems for interior acoustic adaptation along with proprietary solutions of regulated room acoustics for multi-functional spaces (community centers, theaters, home cinemas, etc.)
Their team of experts has developed and is constantly developing acoustic solutions with NEWMAT’s NEW/ACOUSTIC to reduce noise and improve acoustic comfort in homes, apartments, offices, restaurants, public buildings, museums, and open spaces, etc. If you have a need for an acoustical solution, then we are here to help you.

It would be great if the data sheets were easier to find what you need in an efficient time frame. These could be divided into simple labeled categories instead of full length descriptions. Categories such as « Sound Transmission Loss », « Cavity Applications », « Drywall Applications » and so on. This would allow for quicker searches and save from having to scroll the entire page reading lengthy titles to find what you are looking for. Thanks! Also the pictures on the side show an image but when you click on them, that image is not displayed. How can we view that image at a larger scale?

Hi Mr. Brandon Shearin,
My name is Philippe and I’m just the web designer for NEWMAT WORLD… I have to agree with you and I find it very discouraging to go through this page (Acoustical Data) myself.
I would love to make it simpler for you and Acousticians, Architects, Engineers and Owners alike… I wanted to thank you for your input as it gives me some direction as far as how the data should be presented.
Obviously, I’m not an acoustician, the data is quite extensive, and it may take some time, but I wish to follow your suggestions.
By the way, the pictures on the side do open a larger image if you click on them… well.. at least on my side, and I use the most popular browsers. However, the intent for theses pictures to be, is to try to give some kind of reassurance of the content of the PDF which can be viewed by clicking on the View / Download PDF button, which then, open the file in a new tab… You can then download it if you wish.
I will look again into your suggestions and try to improve it for you in the future.
Best Regards,
Philippe
