Instead, suspending an acoustic ceiling below the slab improves the floor-ceiling STC rating by 6-7 points. People experience buildings not just with their eyesight, but with all their senses including the sense of hearing. STONE WOOL ACOUSTIC CEILINGS Acoustic ceilings are one of the few building products and systems that contribute to compliance with multiple performance categories including sound absorption, sound isolation and background noise levels. ACOUSTIC CEILING DESIGN In terms of sound isolation, meeting the minimum STC 50 requirement for floor-ceiling assemblies (i.e., floor to floor vertical sound transmission) is impractical with a concrete structural slab alone.

For over 50 years, the Milser Mühle in Bielefeld has relied on Aerzen rotary lobe blowers for air conveyance. The mill operates around the clock and requires a reliable supply of conveying air to meet delivery deadlines. The current Delta Blower 'Generation 5' units are durable, energy-efficient, and produce oil-free conveying air. They are quieter and have improved sound insulation. The mill also uses special ATEX components for applications in various industries. [Extracted from the article]

The bricks are offered in two formats: 3½" x 2¼" x 75/8" and 3" x 2¾" x 75/8". glengery.com ACRE Zero-waste startup Modern Mill produces this 100% tree-free shiplap siding using upcycled rice hulls. In addition to resisting cracks, splinters, and rot, the wood alternative provides better thermal and sound insulation when compared with real timber. PRODUCTS Venistone Inspired by Venetian breccia, a natural sedimentary rock composed of large fragments, Ceramica Sant'Agostino has developed this porcelain lookalike in six modern neutral colorways with a natural or glossy finish.

Using sound masking as a design platform With mounting recognition of the need to support focus at work as well as to promote wellness, many organizations are looking to improve speech privacy, noise control, and acoustic comfort for building occupants. Indeed, all acoustic design considers this factor - for example, when determining Sound Transmission Class (STC), Articulation Index (AI) or signal-to-noise ratio (SNR). AIA COURSE #K2112M Our company has been dedicated to the design and manufacture of sound masking technologies for more than 40 years. [Extracted from the article]

The article discusses the importance of controlling all aspects of sound in buildings. Topics covered include the need to consider all aspects of sound to achieve a good acoustical design, the need to take a holistic approach to acoustical design, and the various sources of unwanted or interfering sound in building spaces called noise.

Focuses on truck soundproofing. Basic material groups for truck soundproofing; Information on the materials; Benefit of multilayer soundproofing; Ways to improve the environment for drivers.

The article offers practical tips on how to choose proper selection and placement of insulating materials. It has been mentioned that quiet operation effectively gives products a higher perceived value. However, sound insulation can also add weight and assembly cost. With this, a deeper understanding of noise reduction principles can keep the cost-benefit analysis.

Temple-Inland has introduced Silent Guard TS, a mold-resistant version of its existing Silent Guard shaftliner panels. Designed for elevator shafts, stairwells, and area separation walls, Silent Guard maintains the same sound-control and fire-resistance of the traditional product. The TemShield protection system is manufactured in both the core and the surface of the panel and is recognized on the job by a new magenta face paper.

The article discusses various affordable procedures in providing soundproof tracking home studio. It mentions the use of ABF1 Composite foam and SQ125 StratiQuilt Double-Faced Barrier Blanket from Acoustics First Corp. in sealing off windows to lessen the passing of sound. It also cites the purpose of installing solid-core door in the tracking room to block the sounds from inside the room.

The article focuses on the engineering design applications of molded polyurethane foam. It asserts that molded polyurethane foam is not only used to package components, but also for thermal management, acoustical insulation, vibration isolation, and shock mitigation. It also claims that molded polyurethane foam inserts lessen the number of parts in an assembly.

An introduction is presented in which the editor discusses various reports within the issue on topics including production and direction of sound recordings, soundproofing, and sound studios.
