CE Week Bonnie Schnitta A Sound Matter During the CEA LineShows, SoundSense used the dB Focus Tube to confirm the seal of the walls that were installed to separate demo rooms acoustically. They can make your rooms sound better, too. By Bonnie Schnitta, PhD, President, SoundSense LLC Acoustic Separation: Part 1 SoundSense is a full-service acous-tical consulting and engineering company that also offers a com-plete line of acoustic products, experienced installation crews and construction consulting. SoundSense’s main goal is to pro-vide a better quality of life through improved acoustics. SoundSense’s hands-on approach led to the realization that easily locating acoustic leak-age points in walls, floors and/ or ceiling partitions—in order to optimize the performance of these partitions—was of vital impor-tance. From this need, SoundSense developed the first mechanism that would focus sound energy into potential weak links in partitions, such as air gaps typically located around penetrations or at partition intersections. SoundSense devel-oped a portable acoustical testing device, the dB Focus Tube, which is a small mechanism that can eas-ily be transported to and from a job site. SoundSense engineers develop unique solutions with high-quality results. The engineers are responsi-ble for field testing and inspecting the installation of these solutions. The dB Focus Tube enables our engineers and certified installers to test installations quickly and effec-tively. The dB Focus Tube received a patent in March 2011, leading to SoundSense expanding its offices into the Empire State Building in New York City, as well as Los Angeles and Orange County in California. SoundSense utilized the dB Focus Tube to identify areas of acoustic leakage points in the partitions of the CEA LineShows demo room of D-BOX and others. The leakage points were treated by 32 installing SoundSense NoiseOut 2, a proprietary acoustic bar-rier. Specifically manufactured to improve low-frequency transmis-sion loss, the NoiseOut 2 was able to increase the FSTC performance At the CEA LineShows, Lumitex, a fabric in the SoundSense Paradise Nanocloth line, was used to acousti-cally correct the room. Lumitex is a new generation of microfiber cloth that is lightweight and soft, yet incredibly strong. The microfilament structure provides optimal sound absorption for a range of frequencies while providing light reflectance properties for LED lighting designers and manufacturers. of the demo room wall partitions by an average of 10 points. SoundSense’s field testing proved that the mechanism can be utilized by an acoustic engineer or certified installer to locate even the smallest of leakage points in a par-tition which, when sealed, could increase the FSTC performance of the partition by typically 10 points. Additionally, when an engineer is trying to determine the main paths of flanking, the SoundSense dB Focus Tube proves to be an ideal solution. The installer can use the Focus Tube to confirm the opti-mum efficacy of the acoustic treat-ment of PVC piping or duct work acoustic wraps. For example, when wrapping a pipe or duct with a lagging that has a minimum STC of 32, the instal-lation can be tested by placing this tube into one end of the duct or pipe. If the wrap is complete, the sound from the Focus Tube will be barely audible. If the wrap is incomplete, then the sound will be audible. A sound-level meter can then be used much like a Geiger counter to locate the inefficiencies in the wrap. For The CEA LineShows, the dB Focus Tube was used to con-firm the seal of the walls that were installed to acoustically separate one room from another. During 2010, SoundSense final-ized the development of the dB Focus Tube, working to produce a prototype that is production-ready. This past year, SoundSense has been able to—as a result of the dB Focus Tube—ensure better installations, resulting in increased efficiency and efficacy of the end product. The dB Focus Tube allows our engineers to move quickly and to collect the data efficiently to help direct installers and pinpoint prob-lem areas, saving time and energy, thus permitting more time to thor-oughly inspect jobs and ensure the highest quality of work for our clientele. The acoustic application alone has improved our efficiency with time by roughly 20 percent. We have only begun using the Focus Tube in the area of thermal effi-ciency, but preliminary tests have shown it improved efficiency by roughly 10 percent to 30 percent. An initial application demonstrated that windows, which in the past typically required full replacement, can now be upgraded at a signifi-cant cost reduction. Part II: Acoustic Environment Every enclosed space exhibits rever-beration. Reverberation is sound bouncing around the room after the primary sound has stopped. Excessive reverberation reduces the intelligibility of speech, making conversation difficult. Amplified sound from an audio system in a space that is highly reverberant can cause the lack of definition and spatial qualities of the sound. Additionally, a high reverberation time will increase the sound level within a room, making the overall atmosphere unpleasant. SoundSense corrects reverbera-tion by mathematically locating and applying acoustic materials, such as absorbers, reflectors or dif-fusers, at specific locations on or within the boundaries of the room. SoundSense’s proprietary com-puter program optimizes the acoustic environment, creating the Paradise Effect™. SoundSense corrected the reverberation and addressed standing waves of the demo room by mathemati-cally locating and applying various acoustic materials. NoiseOut Acoustic Speaker Back is an innovative, high-performance acoustic enclosure made especially for recessed speakers. It comes as a single unit, com-pletely constructed and ready for installation. It can be used in retrofit and new construction applications. Besides providing a high STC enclosure, this product improves the performance of the enclosed speaker. CustomRetailer • July 2012
